What causes comms loss trip on Invertek Drives Optidrive Plus 3GV Compact?
A comms loss trip on your Invertek Drives Inverter indicates a loss of communication. Check the communication link between the drive and external devices. Make sure each drive in the network has its unique address.
How to fix fast over current trip on Invertek Drives Optidrive Plus 3GV Compact Inverter?
To address a fast over current trip on your Invertek Drives Inverter, start by checking the wiring to the motor for phase-to-phase or phase-to-earth short circuits. Next, assess the drive's ambient temperature to determine if additional space or cooling is needed. Finally, ensure the drive is not being forced into an overload condition.
What causes brake channel over current in Invertek Drives Inverter?
A brake channel over current in your Invertek Drives Inverter is caused by over current in the brake resistor circuit. To resolve this, check the cabling to the brake resistor and the brake resistor value. Ensure minimum resistance values from the rating tables are observed.
What causes heatsink over temperature in Invertek Drives Optidrive Plus 3GV Compact Inverter?
A heatsink over temperature in your Invertek Drives Inverter can be caused by the drive's ambient temperature. Additional space or cooling may be required.
Why Invertek Drives Optidrive Plus 3GV Compact Inverter autotune failed?
The Invertek Drives Inverter autotune may fail because the measured motor stator resistance varies between phases. To solve this, ensure the motor is correctly connected and free from faults. Check the windings for correct resistance and balance.
What to do if Invertek Drives Inverter shows under voltage on DC bus?
This condition occurs routinely when power is switched off. If it occurs during running, check the power supply voltage.
What does internal memory fault mean for Invertek Drives Inverter?
Parameters not saved, defaults reloaded. Try again. If problem recurs, refer to your local Invertek Sales Partner.
What to do if Invertek Drives Inverter shows instantaneous over current?
If the fault occurs immediately when enabling the drive, disconnect the motor cable from the output terminals of the drive and restart it. If the fault re-occurs with no motor connected, contact your local Invertek Sales Partner. If the drive runs correctly with no 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,...
What to do if measured motor inductance is too low on Invertek Drives Optidrive Plus 3GV Compact Inverter?
Ensure the motor is correctly connected and free from faults.
What to do if measured motor stator resistance is too large in Invertek Drives Inverter?
Ensure the motor is correctly connected and free from faults. Check that the power rating corresponds to the power rating of the connected drive.
