if P-34 = 1 or 3 and the 200W Invertek brake resistor has
been overloaded.
•
Increase the deceleration ramp in P-04.
•
The resistor power rating is too small for the regenerated energy. Increase resistor
power rating and set P-34 = 2 or 4.

Internal cooling fan fault (IP66 units only).
•
There is an internal cooling fan on the IP66 units. This fan is monitored to make sure
that it is rotating. If the fan stops rotating, the drive will trip on

Autotune fault (See P-52).
•
The motor parameters measured during an autotune are incorrect.
•
Check the motor cable and connection between the drive and motor.
•
Check the motor cable for continuity between drive and motor.
•
Check all 3 motor phases are present and balanced.

Drive communications fault between control and power microprocessors
•
Power cycle the drive to see if this clears the fault.
