Question:
If the controller is enabled there is an output frequency at code C0050 which cannot be set to zero although, for example, there is no setpoint at terminal 8 (0 V) and no JOG value is activated either.
Answer:
At code C0140 a value has been set via the keypad which is not zero. The value at C0140 has an additive on the frequency setpoint (NSET1-NADD) and is frozen if, for example, the keypad is disconnected and the value has not been set to zero beforehand.
Remedy:
Set the value at C0140 to 0 Hz.
