1) Several motors cannot be simultaneously controlled as this interlocked in the software.
In addition, the recommended contactor interlocking ensures that only one motor
can be operated.
2) Only required for high–speed special motors.
Fig. 9-30 Motor changeover at the SIMODRIVE 611 IM module
For motor changeover, an auxiliary contactor 3RH11 and a main contactor
3RT10 are required for each motor.
A binary–coded switching command is connected to select input terminals
En/En + 1 (max. two terminals for four motors) to changeover a motor. The
changeover command is only executed when the drive pulses are inhibited. In
this case, one of the terminals 663, 65 or 81 (function: Pulse inhibit) must be
opened. After the pulses have been inhibited, the active motor parameter set is
loaded and the motor auxiliary contactors controlled via select relay.
