4.5 Faults
Fault Display Description Cause Countermeasures
FRH
Feedback Range
High
PID feedback out of range
(high). Motor will coast to a
stop.
P1-01 = 4 or 5 and the PID
feedback has exceeded the
P1-02 level for the time set
in P1-03.
Correct the cause of the
high feedback signal.
FRL
Feedback Range
Low
PID feedback out of range
(low). Motor will coast to a
stop.
P1-01 = 4 or 5 and the PID
feedback has fallen below
the P1-05 level for the time
set in P1-06.
Correct the cause of the
low feedback signal.
