Checkthe motor nameplate data to confirm that the correct controller model is beingused. Check for mechanical obstruction or damage.INV_ERROR_OC2 Overcurrent 150%/30 sec(Low Priority) The motor current exceeds the inverter ratingby 150% for more than 30 secondsView the Motor Current display to see the current delivered to the motor. Checkthe motor nameplate data to confirm 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. Decreasethe acceleration rampsINV_ERROR_OC4 Overcurrent DC/Brake(Medium Priority) Overcurrent while DC braking View the Motor Current display to see the current delivered to the motor. Decreasethe DC Brake level.INV_ERROR_OC5 Peak overcurrent(High Priority) Severe overloadCheck for:a short in the motor cablestalled motormechanically or electrically damaged motor.If equipped with a parking brake, ensure that it is being released. Decrease theBoost parameters.INV_ERROR_OH Controller overheat(High Priority) The inverter is overheatedView System Status - Temperature to check that the reported temperature iswithin range. Check ventilation and ensure fan, if present, is operating. Reset thecontroller and confirm that the fan operates for 1 second during the power-uproutine. Reduce the duty cycle of the door.INV_ERROR_12V Low internal 12v(Top Priority)The internal 12V DC power supply voltage istoo lowView the System Status - Int Levels to check that the voltage is within range. CheckI/O wiring for shorts.INV_ERROR_24V Low internal 24v(Top Priority) The internal 24V DC power supply voltage istoo low View the System Status - Int Levels to check that the voltage is within range. CheckI/O wiring for shorts.
