Unit's digit:
0: No closed-loop feedback loss detection
1: There’s a closed-loop feedback loss detection, when the feedback value is less
than or equal to the feedback disconnection detection value and the feedback
disconnection detection time has passed, the drive reports a PID feedback
disconnection fault (E020).
2: There’s a closed-loop feedback loss detection, when the feedback value is less
than or equal to the feedback disconnection detection value and the feedback
disconnection detection time has passed, the drive stops according to deceleration
time 4, while the alarm output terminal has an output, after a delay of 10S, the output is
disconnected.
4. There’s a closed-loop feedback loss detection, with the function same as 2. The
difference is that the feedback value is greater than or equal to the feedback disconnection
detection value.
5: When the closed-loop feedback is greater than the setting of F8.37 and is hold
for the set time of F8.38, the drive starts to sleep, and there’s lower limit signal output.
This function is used for emergency stop at overpressure during PID water supply.
