Master/slave operation, SIMODRIVE 611
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 (ter-
minals 75.x/15 or terminals 16.x/15).

Warning
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.
