Cause: Overcurrent comes when the motor is trying to drive a load that is too heavy, causing it to draw more current. This could be due to a mechanical jam, binding, or the load being significantly larger than expected.

vlt micro drive alarm 13 indicates Overcurrent condition. This means the drive detects that the motor is drawing excessive current, exceeding the drive's current limits.

Troubleshooting Steps:

Follow these steps to correct vlt micro drive alarm 13:

• Check the Mechanical Load: Ensure the motor and the driven equipment are free from any mechanical jams or blockages.
• Inspect Motor and Wiring: Visually check the motor cable for any signs of damage or short circuits.
• Verify Motor Parameters: Ensure that the motor parameters (voltage, current, speed, frequency) programmed in the drive match the motor's nameplate data.
• Adjust Acceleration/Deceleration Times: Try increasing the ramp-up and ramp-down times to reduce the rate of current increase.
