PID Feedback Loss
Detection Selection
All Modes
0: No fault. Digital output only.
1: Fault detection. Alarm output, drive continues operation.
2: Fault detection. Fault output, drive output is shut off.
3: No fault. Digital output only. No fault detection when PID control is
disabled.
4: Fault detection. Alarm is triggered and drive continues to run. Fault
detection even when PID is disabled.
5: Fault detection. Drive output shuts off. No fault detection when PID control
is disabled.
