How to resolve maximum torque limit exceeded on Invertek Drives DC drive?
- EEric BurnsSep 2, 2025
To resolve this issue, reduce the motor load or increase the acceleration time.
How to resolve maximum torque limit exceeded on Invertek Drives DC drive?
To resolve this issue, reduce the motor load or increase the acceleration time.
What does input phase loss trip mean on Invertek Drives DC drive?
The drive is intended for use with a 3-phase supply, and one input phase has been disconnected or lost.
How to reduce excessive DC ripple in Invertek Drives DC drive?
Check that all three supply phases are present and within the 3% supply voltage level imbalance tolerance. Reduce the motor load. If the fault persists, contact your local Invertek Drives Sales Partner.
What causes brake resistor overload in Invertek Drives DC drives?
Always ensure the brake resistor is being operated within its designed parameter before making any parameter or system changes. To reduce the load on the resistor, increase deceleration time, reduce the load inertia or add further brake resistors in parallel, observing the minimum resistance value for the drive in use.
What causes under voltage on DC bus in Invertek Drives DC drive?
If under voltage occurs during running, check the incoming supply voltage and all connections into the drive, including fuses and contactors.
How to lower ambient temperature for Invertek Drives DC drive?
Ensure the drive's internal cooling fan is operating. Verify that the required space around the drive has been maintained, and the cooling airflow path is not restricted. Increase the cooling airflow to the drive. Reduce the effective switching frequency setting in parameter P2?24. Reduce the load on the motor / drive.
How to troubleshoot hardware over current in Invertek Drives DC drive?
Check the wiring to the motor and the motor itself for phase-to-phase and phase-to-earth short circuits. Disconnect the motor and motor cable, then retest the drive. If the drive still trips without the motor connected, it needs to be replaced, and the entire system should be thoroughly checked before installing a replacement.
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.
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.
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.
