3. Open the motor contactor:
Motor contactor 1 is opened r0830 = 0 and the status bit "Motor data set changeover
active" (r0835.0) is set.
4. Change over the drive data set:
The requested data set is activated (r0051 = requested data set).
5. Energize the motor contactor:
After the feedback signal (motor contactor opened) for motor contactor 1, the appropriate
bit of r0830 is set and motor contactor 2 is energized.
6. Enable the pulses:
After the feedback signal (motor contactor closed) for motor contactor 2, the bit "motor
changeover active" (r0835.0) is reset and the pulses are enabled. The switchover is
complete.
11.3.4 Integration
The motor switchover function is integrated in the system as follows.
