Interaction with other functions:
● Essential service mode
The activated "Essential service mode" function influences the "Bypass" function.
Essential service mode (Page 429)
● Converter control
For operation of the motor on the line supply, the converter no longer responds to the OFF1
command, but rather only to OFF2 and OFF3.
● Temperature monitoring for the motor
The converter evaluates the temperature sensor in the motor, also for line operation of the
motor.
Motor protection with temperature sensor (Page 409)
● Disconnecting the converter from the line supply
If for line operation of the motor, you disconnect the converter from the line supply, the
converter opens the K2 contactor and the motor coasts down.
To operate the motor on the line supply also for deactivated converter, the higher-level
control must supply the signal for the K2 line contactor.
