PID Feedback Loss
Detection Selection
Configures the PID feedback loss detection. With all setting
a digital output programmed for H2-01, H2-02, H2-03 =
3E/3F (PID feedback low/PID feedback high) is operated
when the detection condition becomes true.
0: Digital output only.
1: Feedback loss detected when PID enabled. Alarm
output, operation is continued without triggering a fault
contact.
2: Feedback loss detected when PID enabled. Fault output,
operation is stopped and a fault contact is triggered.
3: Feedback loss detection even when PID is disabled by
digital input. No alarm/fault output.
4: PID Feedback error detection even when PID is disabled
by digital input. An alarm is triggered and the drive
continues to run.
5: PID Feedback error detection even when PID is disabled
by digital input. Fault is triggered and output is shut off.
