Fault code Fault type Possible cause Solution
OC3
[6] Overcurrent
during constant
speed running

Load transient or
excepetion occurred.

To-ground short circuit or
output phase loss occur.

There is strong external
interference.
larger power.

Check whether the
load is short circuited
(to-ground short circuit
or line-to-line short
circuit) or the rotation
is not smooth.

Check the output
wiring.

Check whether there is
strong interference.
OV1
[7] Overvoltage
during acceleration

Exception occurred to
input voltage.

There is large energy
feedback.

Check the input power.

Check whether load
deceleration time is too
short, or the motor
starts during rotating.

Install dynamic braking
units.
