How to resolve cooling fan fault on Invertek Drives DC drive?
Check and if necessary, replace the drive internal cooling fan.
Why is there over voltage on the DC bus in my Invertek Drives DC drive?
Over voltage on the DC bus is generally caused by excessive regenerative energy being transferred from the load back to the drive. If the fault occurs on stopping or during deceleration, increase the deceleration ramp time P1?04 or connect a suitable brake resistor to the drive. If operating in Vector Mode, reduce the speed loop gain P4?03. If operating in PID control, ensure that ramps are active by reducing P3?11.
How to fix heatsink over temperature on Invertek Drives DC drive?
Check the drive's ambient temperature and ensure the internal cooling fan is working. Make sure there's enough space around the drive for proper airflow, and that the cooling path isn't blocked. You can also try reducing the switching frequency in parameter P2?24 or decreasing the load on the motor/drive.
What to do if Invertek Drives DC drive trips on overload?
If your drive trips on overload after exceeding 100% of the value in P1?08, first check when the decimal points are flashing, indicating an overload. Increase the acceleration rate or reduce the load. Ensure the motor cable length is within specified limits. Verify that the motor nameplate parameters (P1?07, P1?08, P1?09) are correctly entered. If using Vector mode (P4?01 – 0 or 1), check the motor power factor in P4?05 and ensure a successful autotune. Also, check the load for any mechanical issues like jams or blockages.
What to check for external trip on Invertek Drives DC drive?
If a motor thermistor is connected check if the motor is too hot.
What causes speed error on Invertek Drives DC drive?
The error between the measured encoder feedback speed or the estimated rotor speed is greater than the pre?set limit allowed.
What to do if measured motor stator resistance varies between phases on Invertek Drives DC drive?
Ensure the motor is correctly connected and free from faults. Check the windings for correct resistance and balance.
How do I troubleshoot a CAN Open comms trip on my Invertek Drives DC drive?
Check that the network master / PLC is still operating. Check the connection cables. Increase the value of P5?06 to a suitable level.
How to resolve brake channel over current on Invertek Drives DC drive?
Ensure the connected brake resistor is above the minimum permissible level for the drive. Check the brake resistor and wiring for possible short circuits.
