CONTROL PANEL ERROR MESSAGES - INVERTER ERROR CODES
CODE DESCRIPTION PROBLEM POSSIBLE SOLUTION
INV_ERROR_UU
DC Link low
(Top Priority)
The incoming mains voltage is too low View System Status - DC Link to check that the voltage is within the range shown.
INV_ERROR_OU
DC Link high
(Medium Priority)
Either the incoming mains voltage is too high
or the deceleration rate is to short
View System Status - DC Link to check that the voltage is within the range shown.
Decrease the deceleration ramps.
INV_ERROR_OC1
Overcurrent 210%
(Low Priority)
The motor current exceeds the inverter rating
by 210%
View the Motor Current display to check the current delivered to the motor. Check
the motor nameplate data to conrm that the correct controller model is being
used. Check for mechanical obstruction or damage.
INV_ERROR_OC2
Overcurrent 150%/30 sec
(Low Priority)
The motor current exceeds the inverter rating
by 150% for more than 30 seconds
View the Motor Current display to see the current delivered to the motor. Check
the motor nameplate data to conrm that the correct controller is being used.
Check for mechanical obstruction or damage.
INV_ERROR_OC3 Overcurrent during acceleration Overcurrent while accelerating
View the Motor Current display to see the current delivered to the motor. Decrease
the acceleration ramps
INV_ERROR_OC4
Overcurrent DC/Brake
(Medium Priority)
Overcurrent while DC braking
View the Motor Current display to see the current delivered to the motor. Decrease
the DC Brake level.
INV_ERROR_OC5
Peak overcurrent
(High Priority)
Severe overload
Check for:
a short in the motor cable
stalled motor
mechanically or electrically damaged motor.
If equipped with a parking brake, ensure that it is being released. Decrease the
Boost parameters.
INV_ERROR_OH
Controller overheat
(High Priority)
The inverter is overheated
View System Status - Temperature to check that the reported temperature is
within range. Check ventilation and ensure fan, if present, is operating. Reset the
controller and conrm that the fan operates for 1 second during the power-up
routine. Reduce the duty cycle of the door.
INV_ERROR_12V
Low internal 12v
(Top Priority)
The internal 12V DC power supply voltage is
too low
View the System Status - Int Levels to check that the voltage is within range. Check
I/O wiring for shorts.
INV_ERROR_24V
Low internal 24v
(Top Priority)
The internal 24V DC power supply voltage is
too low
View the System Status - Int Levels to check that the voltage is within range. Check
I/O wiring for shorts.
