Remedy: Check the encoder selection configuration (p1192).
Note:
If there is no encoder and connector input p1191 (DSC position controller gain) is interconnected, then connector input
p1191 must have a 0 signal.
F07430 Drive: Changeover to open-loop torque controlled operation not possible
Message value: -
Drive object: All objects
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: For encoderless operation, the converter cannot change over to closed-loop torque-controlled operation (BI: p1501).
Remedy: Do not attempt to cover over to closed-loop torque-controlled operation.
F07431 Drive: Changeover to encoderless operation not possible
Message value: -
Drive object: All objects
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: For closed-loop torque control, the converter cannot change over to encoderless operation (p1404).
Remedy: Do not attempt to change over to encoderless operation.
F07432 Drive: Motor without overvoltage protection
Message value: %1
Drive object: All objects
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: In the case of a fault at maximum speed, the motor can generate an overvoltage that can destroy the drive system.
