State
• Increase deceleration ramp
• Check motor insulation using a insulation tester
• Increase acceleration/deceleration rate
• Check for short circuit on the output cabling
• Check integrity of the motor insulation using an
insulation tester
over current has been detected in braking IGBT or
braking IGBT protection has been activated
There is a hardware fault within the drive – return
the drive to the supplier
• Check motor temperature
• Check the thermal sensor.
Check that a mechanical load is not driving motor
the output current of the drive exceeds the trip
level
• Check brake resistor wiring
• Check braking resistor value is greater than or
equal to the minimum resistance value
• Check braking resistor insulation
The drive has tripped during a rotating autotune or
mechanical load measurement test.
Check motor cable wiring is correct
The drive was prevented from completing an
autotune test, because either the drive enable or
the drive run were removed.
Check the drive enable signal (Terminal 11) was
active during the autotune
• Ensure the load is not jammed / sticking
• Check the load on the motor has not changed
• Tune the motor rated speed parameter (Pr 5.008)
(RFC-A mode only)
• Ensure the motor rated current is not zero
