5X00622G01 Output expansion module

The controller can be expanded with axis expansions consisting of up to five (four) axes + one spindle with separately attached power units. The closed–loop controls are already integrated into the CCU modules. Just like the SINUMERIK 840D, the control power supply is taken from the NE module power supply via the equipment bus. The NC ready signal acts on the ready signal terminal 72–74 of the NE module via the equipment bus. The control has one hardware terminal 663 pulse enable/start inhibit for all axes together. The closed–loop controllers and pulses are enabled on an axis–for–axis basis and are controlled on the digital internal drive bus via NC/PLC interface signals. The safety–relevant drive–related control for a machine/system with SINUMERIK 810D can be engineered on the user–side based on the circuit examples in Section 8.7.

If the rigid mechanical coupling is released, then the slave drive must be simultaneously changed–over to ”closed–loop speed control” as otherwise inadmissibly high speeds could occur, which could result in malfunctions.

Circuits with 611 universal HRS

 The SIMODRIVE 611 universal HRS control board is available as either 1–axis or 2–axis module. The setpoint can either be entered as analog signal or via PROFIBUS. The interfaces are described in Chapter 4. Implementation of the safety–relevant, drive–related control for a machine. The SIMODRIVE 611 universal control board with analog setpoint interface can be used in a comparable fashion to the circuit examples =1 to =9 in Section 8.7.Two SIMODRIVE main spindle drives can be operated, rigidly and mechanically coupled together if the master drive is closed–loop speed controlled and the slave drive is closed–loop torque controlled. The application of a master/slave function with ”SIMODRIVE 611 universal HRS” is shown in the following example: The master specifies the torque setpoint for the slave via an analog output (terminals 75.x/15 or terminals 16.x/15).

Star–delta mode

 SIMODRIVE 611 supports the use of motors that can changeover between star/ delta configurations. At lower speeds, the drive is operated in the star circuit configuration (high torque) and at higher speeds, in the delta circuit configuration (high stall torque). Changeover is also possible during operation. The speed when changing–over from a star into a delta configuration (star to delta operation) must lie within the stall power range for star operation (refer to the speed–torque diagram for Y/Δ operation). A star–delta changeover is only permitted below the star field–weakening speed.

During the phase when changing–over from Y to Δ operation, no torque may be demanded from the 1PH motor. In this case, a minimum dead time of 0.5 s must be taken into account for contactor changeover times, safety margins, de–magnetizing and magnetizing operations.
