Cause : Drive Overload comes when drive Thermal Percentage (P1.23) is > 95 %. The alarm will be cleared when Drive Thermal Percentage (P1.23) is < 75 %.
If you're encountering a "Drive Overload" fault in a Commander S100 drive, it typically implies that the drive itself is experiencing an overload condition.
-
Check Load Conditions: Ensure that the load being driven by the motor isn't too heavy for the drive to handle. If the load exceeds the capabilities of the drive, it can lead to overload faults. Verify if the load is within the rated capacity of the drive.
-
Inspect Motor Parameters: Review the parameters set for the motor in the drive's configuration. Ensure that the parameters are correctly configured according to the motor's specifications. Incorrect parameter settings can lead to overload conditions.
-
Monitor Current Draw: Utilize the drive's monitoring features to observe the current draw. If the current exceeds the rated capacity of the drive, it can trigger an overload fault. Investigate any sudden spikes or abnormal fluctuations in current draw.
-
Check for Mechanical Issues: Inspect the mechanical components connected to the drive, such as belts, couplings, and gears. Any mechanical issues such as misalignment, binding, or excessive friction can lead to increased load on the drive, causing overload faults.
-
Verify Cooling and Ventilation: Ensure that the drive is adequately cooled and ventilated. Overheating can cause the drive components to malfunction and trigger overload faults. Clean any dust or debris obstructing the ventilation paths and verify that cooling fans are functioning correctly.
- Reduce load on motor or ambient temperature of the drive.
