SIMODRIVE main spindle drives combine the advantages of induction motors - rugged and low-maintenance - with state-of-the-art microprocessor technology. Using the TRANSVEKTOR closed-loop control developed by Siemens, it has become possible to control asynchronous induction motors with a control quality comparable to that of DC drives. Digital technology allows extremely short startup times by presetting the main spindle drive, as well as a comprehensive measuring and diagnostics system. With these characteristics, SIMODRIVE AC main spindle drives fulfill all requirements demanded of a drive concept for machine tools in modern production facsities: e fast startup e High degree of operator friendliness and simple diagnostics High operational reliability Very low maintenance e Simple reproducibility of set values, e.g. during servicing e large speed range at constant power e Reduces number of mechanical gear stages Fig. 1.7 1PH6 AC motors and SIMODRIVE 650 transistor PWM converter Siemens AG 1990 All Rights Reserved 6ZB5 420-0AH02-0BA0 1-1 AC main spindle drives Description } re *1 AC main spindle drives 1.1 Application Important AC motor characteristics: Rugged and low maintenance four-pole squirrel-cage induction motors Short torque rise time Short speed rise time Low moment of inertia Full motor torque, even continuously available at standstill Good smooth running characteristics even at the lowest speeds Shaft bearings suitable for machine tool applications No speed-dependent power limiting as a result of commutation Constant power range 1:4 to 1:16 Speed control range > 1:1000, with "C axis option >1:500 000 Speeds down to 0 for C axis operation and positioning Short design length Short distance between bearings providing high vibrational Stability Figh degree of protection : IP 54 Externally cooled from the drive end to non-drive end Position and speed are brushlessly sensed Motor temperature monitoring Wide spectrum providing harmonized power steps Options: - Holding brake ~ Gearboxes Space heaters iP 55 degree of protection important characteristics of transistor PWM converters: 1-2 Can be directly connected to the supply without transformer, commutating reactors, and in-rush current limiting Regenerative feedback into the line supply during braking Digital multiprocessor concept for speed and torque closed-loop control High long-time accuracy of the closed-loop control parameters Load and control characteristics similar to a OC motor as a result of freld-orientated closed-loop control Simple and fast digital parameter input Operating and fault message display High degree of safety using monitoring circuits Microprocessor based diagnostics Options: - Spindle positioning - Main drive as C axis Siemens AG 1990 All Rights Reserved 62ZB5 420-0AH02-0BA0 AC main spindle drives Description1 AC main spindle drives 1.1 Application SIMODRIVE 650 PWM converter and 1 PH6 motors with ratings from 3 to 75 kW at speeds from 500 to 2000 RPM.

Two microprocessors digitally represent the current and speed closed-loop circuits, and calculate the field. The open-loop and closed-loop control of the AC main spindle drive consists of a closed-loop speed controller with ramp-function generator and stored field weakening characteristic, as well as a secondary closed-loop torque control circuit and control system for the inverter and sequence control. While AC drives used up until now always represented a non-linear controlled system, here, for the first time, there ts a linear relationship, where the induction motor behaves similar to a DC motor and where the armature current (with constant excitation) is proportional to the torque.

Block diagram of the SIMODRIVE AC main spindle drive It is possible to rapidly change the stator voltage and frequency of the AC motor using the transistor converter. Further, the magnetic flux and torque are decoupled. The decoupling of these two motor variables is simulated in a microprocessor computer model. The reference variables for the motor supply, frequency, phase position and amplitude are generated using this computer model in order to provide each required torque and magnetic field, taking into account the torque and field limits. The resulting stator current vector is divided into a rotor flux and torque generating current components to the rotor flux. Field- orientated operation is provided if the current components generating the motor flux remain constant and the current components generating the torque are built up vertically to the rotor flux corresponding to the required torque. Siemens AG 1990 All Rights Reserved 62ZB5 420-0AH02-0BA0 1-5 AC main spindle drives Description1 AC main spindle drives 1.2 Mode of operation This method of generating the current vector orientated to the flux vector position (field () orientation) allows the torque and flux to be separately controlled and provides a closed-loop control quality similar to that for DC drives. Two microprocessors are used in order to be able to execute arithmetic operations sufficiently fast for this closed-loop control concept. The current and speed controller circuits and the open-loop control are digital. Digital technology provides a high degree of user friendliness and a high level of reproducibility of the setting variables. The parameters required for the closed-loop control are stored in a non-volatile EEPROM, which can also be used in other PWM converters. 1.3 Complete standard drives The standard drives available are listed in Table 1.1. A suitable PWM converter is allocated to each AC motor depending on the required overload capacity. The available overload Capacity refers to S6 or S3 operation with a duration of 10 minutes. Contrary to DC technology, there is no linear relationship between current and torque of AC motors as a result of the magnetization current. Thus, the currents necessary for the required overload capacity of a specific AC motor are already taken into account for the required PWM converter in Table 1.1. The PWM converter thermal time constant is significantly lower than that of AC motors. The converters are thermally dimensioned for continuous operation. Further, the 6SC6512 and 63C6520 units have an overload capability. These characteristics are taken into account in the table below. The on-period in S6 or $3 operation should be taken from the motor data sheets. 1-6 Siemens AG 1990 Al Rights Reserved 627B5 420-0AH02-0BAQG AC main spindle drives Description1 AC main spindie drives 1.3 Complete standard drives PWM converter for nx overload capacity Te fe pw Pe AC motor 1PH6101-4CF4 6SC6502 | 6SC6502 | 6SC6502 | 6SC6502 1PH6101-4CG4 6SC6502 | 6SC6502 | 6SC6502 | 6SC6503 1PH6103-4CF4 65C6502 | 6SC6502 | 6SC6503 | 6SC6503 1PH6103-4CG4 6SC6S02 | 6SC6503 | 6SC6503 | 6SC6503 1PH6105-4CF4 65C6503 | 6SC6503 | 6SC6503 |6SC6504 1PH6105-4CG4 6SC6503 | 6SC6503 | 6SC6504 | 6SC6504 1PH6107-4CC4 65C6503 | 6SC6503 | 6SC6504 | 6SC6504 1PH6107-4CF4 65C6503 | 6SC6503 | 6SC6504 | 6SC6504 1PH6107-4CG4 65C6503 | 6SC6504 | 6SC6504 | 6SCE506 65C6504 65C6506 65C6504 6SC6504 6SC6506 6SC6506 6SC6506 6SC6506 6SC6508 65C6504 65C6504 65C6504 65C6504 6SC6506 6SC6506 65C6506 6SC6506 6SC6508 65C6504 65C6504 65C6503 65C6504 6SC6504 6SC6506 65C6506 65C6506 6SC6506 635C6503 6SC6504 6SC6503 6SC6503 65C6504 6SC6504 6S5C6504 65C6506 6SC6506 1PH6131-4CF4 1PH6131-4CG4 1PH6133-4CB4 1PH6133-4CFO 1PH6133-4CF4 1PH6133-4CG4 1PH6135-4CFQ 1PH6135-4CF4 1PH6135-4CG4 1PH6137-4CB4 6SC6506 | 6SC6506 | 6SC6506 | 6SC6508 1PH6137-4CF4 6SC6506 | 6SC6506 | 6SC6508 | 6SC6508 1PH6137-4CG4 6S5C6506 | 6SC6508 | 6SC6508 | 6SC6508 65C6508 65C6512 65C6512 6SC6508 6SC6508 6SC6512 6SC6506 6SC6508 65C6508 65C6508 6SC6508 65C6508 6SC6508 65C6512 65C6512 6SC6506 6S5C6508 65C6508 1PH6138-4CFO 1PH6138-4CF4 1PH6138-4CG4 1PH6161-4CFO 1PH6161-4CF4 1PH6161-4CG4 1PH6163-4B4 1PH6163-4CFO 1PH6163-4CF4 65C6508 63C6512 6SC6512 65C6512 65C6512 65C6512 65C6508 6SC6508 65C6512 65C6512 6SC6512 65C6512 6SC6506 6SC6508 65C6508 65C6508 6SC6508 65C6512 1PH6163-4CG4 65C6512 | 6SC6512 | 6SC6512 | 6SC6512 1PH6167-4CB4 6S5C6508 | 6SC6512 | 6SC6512 | 6SC6512 1PH6167-4CFO0 65C6508 |6SC6512 | 6SC6512 | 6SC6512 1PH6167-4CF4 1PH6167-4CG4 635C6512 65C6512 65C6512 65C6512 6SC6512 65C6512 6S5C6512 65C6512 1PH6186-4CE4 1PH6186-4CF4 | 50 1PH6206-4CE4 | 63 1PH6206-4CF4 | 76 Table 1.1.

Motor losses and noise have been significantly reduced, and the smooth running characteristics enhanced as a result of this matched system. Maximum speeds of up to 9000 RPM can be attained as a result of the compact mechanical design. 1PH6 AC motors are available with ratings from 3 kW to 75 kW at rated speeds between 500 and 2000 RPM. The motor is available in two standard ranges with a constant power range between 1:5 and 1:6 at rated speeds of 1500 or 2000 RPM as well as a wide range series. This series covers a constant power range from 1:12 or 1:16 at rated speeds from 750 or 500 RPM and above. Thus, gear stages or complete gearboxes can be dispensed with and the drive train stiffness significantly increased. 2.2 Design 1PH6 AC motors have flanges and shafts which are compatible to 1G[]5 DC motors having the same shaft height. The basic motor design consists of: e Active motor component sd NTC thermistor for motor temperature sensing e Encoder system for sensing motor speed and rotor position Standard scope of supply of the 1PH6 range AC squirrel-cage induction motor e iM B3 type of construction (foot mounting) e IP 54 degree of protection e Insulating class F e Vibrational severity R e Terminal box with outlet to the right (without PG gland) 2NTC thermistors in the stator winding Incorporated ROD 323 shaft encoder with 1024 pulses/revolution Anthracite grey paint finish with turquoise ring Siemens AG 1990 Ali Rights Reserved 6ZB5 420-0AH02-0BA0 2-1 AC main spindle drives Description2 AC motors 2.2 Design The AC motors are forced-ventilated. The fans are mounted axially on the non-drive end. In order to discharge the dissipated motor heat away from the machine tool the air flows from the drive end to the non-drive end. For 1PH6 motors (shaft heights 100-160), the air is discharged radially towards the bottom, and the fan can be rotated through 4 x 90. For motors with shaft heights 180 and 200, the radial air discharge can be either to the right or left. Torque can be increased by using speed changing with a mounted gearbox. 1PH6 AC motors are equipped as standard with double bearings on the drive end to accept higher cantilever forces. The permissible cantilever loading can be taken from the diagrams in the Appendix. if vibrational severity SR is required for 1PH6 motors (shaft heights 100-160), deep-groove ball bearings must be used on the drive end, which have a lower cantilever force loading capability. With vibration severity 5, the motors are equipped with single bearings; double-bearing design is possible. We recommend only single-bearing design for operation without cantilever loading (coupling, direct drive with gearbox). 1PH6 AC motors (shaft heights 180 + 200) are also available in IM B3 design with strengthened bearings for accepting increased cantilever forces. The maximum speed is reduced with this design. A two-stage gearbox for extending the constant power range as well as a holding brake are available as option for mounting to the drive-side bearing end shield of the motors. 2.2.1 NTC thermistor Two NTC thermistors are incorporated in the motor stator winding to sense motor temperature. The signals are evaluated in the PWM converter whose closed-loop controller takes into account the temperature characteristic of the motor resistors. An external tripping unit is not required. The NTC thermistor function is monitored. A corresponding message is output on the PWM converter if a fault condition occurs. With increasing motor temperature, a "motor overtemperature prewarning relay signal is output. If this prewarning is not observed, the PWM converter shuts down when the motor limit temperature is exceeded, and issues a corresponding fault message. The second NTC thermistor is a reserve sensor and can be selected by changing over the connections in the motor terminal box. 2.2.2 ROD 323 shaft encoder A shaft encoder is mounted at the non-drive bearing end shield of the motor in order to sense Speed and rotor position. The shaft encoder resolution is 1024 pulses per motor revolution as Standard. The shaft encoder signals can be taken from the PWM converter for external applications. (e.g. transfer to a higher-level position control system). When using the C-axis option (also refer to Section 3.4, Pages. 3-2), this shaft encoder is replaced by a double encoder system with an additional high-resolution track. 2-2 Siemens AG 1990 All Rights Reserved 6ZB5 420-0AHO02-0OBA0 AC main spindle drives Description2 AC motors 2.3 Mode of operation 2.3 Mode of operation lee The constant power range of 1PH6 AC motors is essentially from the rated speed nn up to maximum speed Nmax (5000 RPM, 6500 RPM, 7000 RPM, 8000 RPM or 9000 RPM) 1). Constant torque T, ts available from standstill up to rated speed. At higher speeds, i.e. in the constant power range, the maximum available torque Tmax at a specific speed n is given, in a first approximation, by the formula: AC motors have a large overload capacity in the constant torque and constant power ranges. With some AC motors, the overload capacity is reduced in the vicinity of the maximum speed. Specific information should be taken from the motor characteristics in Section 6. The motor field remains constant in the basic speed range up to the motor rated speed. This is followed by a further constant power range, which is characterized by various gradients as a result of the field weakening.

They control the drive power and speed in 4-quadrant operation. Seven converters are available with ratings between 15 and 150 kVA. The transistor PWM converters are mounted in an enclosure, together with the incoming fuses, and can be connected directly to a 3-phase 380 V AC 50/60 Hz supply. Transformers, commutating reactors, and inrush limiters are not required. Monitoring electronics ensure short-circuit-, overload-, and ground fault protection for the converter. The TRANSVEKTOR closed-loop control concept guarantees high control performance such as is required for C-axis operation. All 1PH6 motor data, required for the field calculation, is deposited in a memory in the converter. During startup, the microprocessor automatically provides the complete motor data. Customer-specific closed-loop control parameters can be entered or changed on a display and operator control unit. During operation, operational statuses and faults are indicated on the 6- digit display of the display and operator control unit. All parameters and fault messages can be displayed in plain text on the programming unit screen with the "interface for connecting PG 685 / 675 programming units option. A data set can be stored on floppy disk, and can be used for other standard machines. 3.2 Design The power section consists of: a line-side converter with regenerative feedback into the supply e a DC voltage link, and a transistor PWM converter which generates a variable-voltage and variable-frequency AC system The electronics is supplied from the DC link, thus providing ride-through capability during brief supply voltage failures. The necessary line-side fuses are incorporated in the pulse converter. Fuses are not blown on Supply voltage failure when the unit is in the regenerative mode.

In the rectifier mode, the thyristors behave like diodes. The gating control uses gating transformers. The closed-loop controller realizes the actual pulse generation and the input/output board and gating board, further processing and amplification. In order to permit regenerative operation with 6 thyristors, the DC link is reversed through the step-up converter, and the thyristors are controlled through the closed-loop control board per software, so that they operate in the inverter mode. The motor-side converter consists of 6 transistors with integrated anti-parallel free-wheeling diodes. A pulse width modulated voltage of 0 to 430 volts is generated by controlling the transistors.

All input signals are conditioned as frequencies, and all output signals as logic signals. The necessary software is stored in five EPROMs. The settings can be transferred unchanged if a PC board has to be replaced. The gating and closed-loop control electronics has two microprocessors, which represent the digital current and speed control loops, and calculate the field. The closed-loop contro} Structure is a speed control loop with ramp-function generator and secondary torque control loop. It is possible to directly input the torque setpoint, bypassing the speed controller. The "orientated spindle stop with higher-level closed-loop position control in a numerical control (NC function M1S) can attain an accuracy of + 0.5 as a result of the extremely accurate closed-loop control concept. Shaft encoders, mounted as standard in the motors, can be used. The position can be maintained, controlled, i.e. joad torques are possible but still maintaining the required position.

The speed setpoint required is input from the positioning control, and any speed setpoint at terminal 56 is suppressed. The search speed ts the highest speed with which the drive can be braked at the target position in one revolution without overshoot. e Position sensing The closed-loop position controller is switched-in after the search speed has been reached. The speed setpoint in this case comes directly from the closed-loop position controller. A search speed 1s input until the target position has been identified. e Travel to final position The actual positioning sequence starts during the final revolution. This ensures that the approach sequence is always the same.

A special double-track encoder, type ROD1250, is used. This encoder has a square-wave track with 1024 pulses per revolution and a track with 18000 sinusoidal-cosinusoidal impulses per revolution, which are subdivided into a further 256 individual steps. This provides a resolution of 4.600.000 steps per revolution and one step corresponds to a mechanical angle of approx. 0.0001. The square-wave track is evaluated, in the normal mode, on the input/output board. The high- resolution encoder track is evaluated on the option board. The square-wave track signals are available on the I/O board for customer use. The high-resolution encoder track is only evaluated below a changeover speed, which can be set with parameter P-108. The P-gain and integral action time are also changed over when changing from one to the other encoder track. This changeover occurs automatically without restricting operation. 3-8 Siemens AG 1990 All Rights Reserved 67B5 420-0AH02-0BA0 AC main spindle drives Description { i { { 4 7 | ( eT eK ek Bk OS ee4 3 Transistor PWM converter 3.4 Options 34.3 "PG coupling board A SIMODRIVE 650 converter can be started up in a user-friendly fashion using a 2G635/675/685 programming unit, using this board. This option includes the interface board for connecting a SIMODRIVE 650 unit, and a program floppy disk for the programming unit. For startup, the interface board is inserted at the plug connector X131 available as standard on the closed-loop control board N1. After startup, the interface board is withdrawn and can be used for other startups. The connection between the programming unit ("print socket) and the aterface board is established using a cable, type 6FC9344-1A (refer to Section 4), which is used as standard for establishing the connection between SINUMERIK and a programming unit or SIMATIC and a programming unit. A 9600 baud transmission rate Is recommended to speed up the transmission. The SIMODRIVE 650 converter startup program is subdivided into "process parameter and transfer data blocks. The converter parameter set is represented, menu prompted, tn the "process parameter block. The enable signals can either be realized in a file, or directly transferred on-line to the converter, so that their effect at the converter can be checked. In this operating mode, converter fault messages are also displayed in plain text on the programming unit screen. Further, it is possible to simultaneously display all operating messages and data of the converter (P-00-P11) on a program screen mask. In addition, the user can generate his own masks for startup purposes. It is possible to store an optimized data set on a floppy disk or on a hard disk, or this data set can be directly transferred to the EEPROM of the converter for transcribing, In the "transfer data block. This capability is especially useful and saves time when starting up standard machines. 3.4.4 External heat dissipation option With this design (option E45), for units 6SC6504, 6SC6506, 6SC6508, 6SC6512 and 6SC6520, the cooling air circuit for the power section is separated from the interior of the machine tool cubicle. In this case, the power section heat dissipation must not be taken into account when dimensioning the cubicle cooling. The incorporated standard filter mat extracts particles having a diameter exceeding 5 pm. The E45 option includes the complete set and cubicle fan, hose connections, outlet filter, and connecting flange. Only 6SC6508 to 6SC6520 converters can be retroffited with the external heat dissipation option. The total duct length cannot be greater than 1.5 m in order to ensure the necessary air-flow rate.

In normal operation, the display indicates the operating conditions. When a fault condition occurs, the fault is indicated which caused the shutdown. The parameters are preset in the factory but can however be changed as required. The drive parameters are set using two keys, which increase or decrease the value indicated in the display. The longer a key is pressed, the faster the displayed value is changed. The display mode is changed with the P key (operational display/number of the operational display or display of the parameter value/parameter number). The parameters can be changed in steps of at least one part per thousand. The parameter is entered in a physical dimension, percentage or in hexadecimal format. Customer-specific parameters for standard series-production machines can be completely entered in a programmed EEPROM. The motor data, necessary for the field calculation is retrieved from a stored file (EPROM) by entering a motor identification code. Startup can be executed, menu prompted, with a programming unit. Once the settings have been optimized, the data set can be stored in the programming unit, and when starting up identical machine tools, can be completely transferred to the converter.

Transistor PWM converter 3.6 PWM converter - Interfaces 3.6 3.6.1 PWM converter - Interfaces Inputs e Analog signals: Speed setpoint Nset1 (0 V to + 10 V) Speed setpoint Nget2 (0 V to +10 V) Torque setpoint e Binary signals: (can be driven, floating, with internal or external voltage) 3-12 Direct pulse suppression (terminal 63) (If this terminal is de-energized with the drive running, the motor idles down to standstill. This terminal directly influences the line- and motor-side converters. } Closed-loop contro! enable (terminal 64) (lf this terminal is de-energized, the drive brakes down to standstill with the selected ramp-down time. The motor is switched-off (no-voltage condition) when the speed Is zero. At switch-on, the time constant for the re-magnitization must be taken into account.) Ramp-function generator - Fast stop (terminal 81) (If this terminal is de-energized, the drive is braked down to standstill with the maximum torque. The motor remains magnetized at standstill.) Limiting torque - Reduction (terminal 111) (When the terminal is energized, the maximum motor torque is reduced to a set value, dependent on reaching a selectable speed limit.) Oscillating setpoint for gear change (terminal 60) (When this terminal is energized, an internal drive oscillation is generated, which has a variable frequency and amplitude, in order to facilitate gear change. Setpoints, if available, are suppressed.) Set ramp-function generator to zero (terminal 62) (Ramp-function generator disabled) Selection of four speed controller settings and limiting torques for various gear stages Closed-loop torque control (terminal 158) (The torque setpoint of the master drive can be fed to the slave drive, for example for a twin drive. In this case, the master drive is speed controlled, and the "slave" drive is torque controlled in a open-loop fashion.)
