Cause: I2T MOTOR TRIP comes when the motor's thermal overload protection (I²t) has tripped. This protection is designed to prevent the motor from overheating due to prolonged overcurrent conditions, which can damage the motor windings.

MI2T I2T MOTOR TRIP fault in Parker AC890 drive indicates the motor has been overloaded thermally over time, based on the drive’s I²T (current squared time) protection model.

Troubleshooting Steps:

• Check the Application: The most frequent cause is that the mechanical load on the motor is too high, causing it to draw excessive current. Analyze the application's demands.
• Reduce the Load: If the motor is consistently overloaded, you need to reduce the mechanical load, optimize the process, or consider using a larger motor.
• Verify Motor Nameplate Data: Double-check that the motor parameters programmed into the AC890 drive (especially the motor rated current) exactly match the motor's nameplate.
• Run Motor Autotune (if applicable): While primarily for vector control, autotuning can sometimes help the drive better identify the motor's characteristics relevant to thermal protection.
