Cause: Current limit comes when the drive is limiting output current to protect itself or the motor, but it hasn’t tripped yet. This is a warning, not a fault, but it's a sign that something's pushing the motor hard.

a0501 micromaster 440 indicates a "Current limit" condition. This means the drive has reached its internal current limit to protect itself and the motor from overcurrent. The drive might reduce the output frequency or voltage to limit the current, which could result in reduced motor performance.

Troubleshooting Steps:

• Check Motor and Drive Ratings: Verify that the motor's rated power is within the MICROMASTER 440's power rating.
• Inspect Motor Cable: Ensure the motor cable length is within the permissible limits specified in the drive manual.
• Check the Motor: Inspect the motor for any signs of overheating or damage.
• Verify Motor Parameters: Double-check all motor parameters programmed in the drive against the motor nameplate.
