F.410
(Mtr OC L1)
(motor over current
limit 1)
Over current.
1. Mechanical problem
2. Motor brake not releasing
3. Motor nameplate parameters (frequency,
current, etc.) incorrectly set
4. Motor torque boost incorrectly set
NOTE: Parameter P:140 (open boost)
or P:145 (close boost) set too
high.
1. Check operation of door
2. Check brake
3. Check motor parameter settings and
verify settings match listing on motor
nameplate
4. Consult factory
F.425
(Power OV)
(power over voltage)

1. Incoming voltage too high 1. Check parameter P:940 =
incoming voltage to control board
F.426
(Power Low)
(power low)
Low supply voltage.
1. Incoming voltage too low 1. Check parameter P:940 =
