Instantaneous over current on drive
output.

Over temperature on the drive
heatsink
If the fault occurs immediately when enabling the drive, disconnect the motor cable from the output
terminals of the drive and restart the drive. If the fault re-occurs with no motor connected, contact
your local Invertek Sales Partner. If the drive runs correctly with not motor connected, check the
motor, motor cable and any connections or junction boxes for phase – phase and phase – earth short
circuits. Wherever possible, motors and connection cables should be checked with a high voltage
insulation tester (Megga) prior to connection to the drive.
Ensure that no switching devices, such as contactors or local isolators are switching during operation of
the drive.
Check the motor cable length does not exceed the specified maximum
Ensure the motor nameplate parameters are correctly entered, P1-07, P1-08, P1-09. If operating in
Vector mode (P4-01 – 0 or 1), also check the motor power factor in P4-05.
Ensure an autotune has been successfully completed for the connected motor.
Check the load mechanically for a jam or stalled condition, or shock loads.
Increase the ramp up time in P1-03.
If operating in Vector mode (P4-01 – 0 or 1), reduce the speed loop gain in P4-03

Drive has tripped on overload after
delivering >100% of value in P1-08 for
a period of time.
Check to see when the decimal points are flashing (drive in overload) and either increase acceleration
rate or reduce the load. Check motor cable length is within spec. Ensure the motor nameplate
parameters are correctly entered, P1-07, P1-08, and P1-09. If operating in Vector mode (P4-01 – 0 or
1), also check the motor power factor in P4-05. Ensure an autotune has been successfully completed
for the connected motor. Check the load mechanically to ensure it is free, and no jams, blockages or
other mechanical faults exist
