Chapter 14 Fault CodesMS300
581
PID feedback loss (analog feedback signal is only valid
when the PID function is enabled)
When the analog input < 4 mA (only detects 4–20 mA analog input)
Fault Treatment Parameter
Pr.08-09
0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: Warn and operate at last frequency
When Pr.08-09 = 3 or 4, AFE is a “Warning”. When the feedback
signal is > 4 mA, the ”Warning” is automatically cleared.
When Pr.08-09 = 1 or 2, AFE is a “Fault”. You must reset manually.
When Pr.08-09 = 1 or 2, AFE is a “Fault”, and the fault is recorded; when Pr.08-
09=3 or 4, AFE is a “Warning”, and the warning is not recorded.
PID feedback cable is loose or cut
off
Tighten the terminal.
Replace the cable with a new one.
Replace the device with a new one.
Check all the wiring. If AFE fault still exists, return to the factory for repair.
