NOTE
In the event of an "OC6" (Motor Overload) failure there is a 3-minute delay before resetting
is possible. This is a requirement of UL508C. This delay is intended to allow time for the
motor to cool.
If power is removed when the drive is in an "OC6" fault state, when the power is restored
the "OC6" fault will still be present and the delay will still be active even if power was
removed for longer than 3 minutes.

Grounded motor phase
Excessive capacitive charging
current of the motor cable
t overload) Motor is thermally overloaded,
2
due to:
• impermissable continuous current
• frequent or too long acceleration
processes
Controller too hot inside
Mains voltage too high
Excessively short deceleration time
or motor in generator mode
Earth leakage on the motor side
More than 8 errors in 10 minutes
4-20 mA signal is below 2 mA
(C34 = 4)
A mains phase has been lost
Cause
Check motor/motor cable
Use shorter motor cables with lower
charging current
• Check controller selection
• Check setting of c20
• Reduce controller load
• Improve cooling
Check mains voltage
Increase deceleration time or use
dynamic braking option
Check motor/motor cable
(separate motor from controller)
Depends on the error
Check signal/signal wire
Check mains voltage
