Motor Timed Overload Trip (Adv. Code 0)

What does 20 mean?

This fault signifies that the motor connected to the drive has experienced an overload condition exceeding the customer-defined overload settings. Sustained operation above the motor's rated current can lead to winding damage, reduced motor lifespan, or premature motor failure. The drive tripped to protect the motor.

Complete Troubleshooting Guide

1. 1

   Evaluate the mechanical load on the motor and reduce it if it exceeds the motor's capabilities. Check for any mechanical binding or obstructions.

2. 2

   Verify that the Motor Full Load Amperage (FLA) parameter in the drive is programmed correctly and matches the motor's nameplate rating.

3. 3

   Confirm that the Timed Overload (TOL) characteristic (e.g., thermal model) is appropriately configured for the specific motor and application (e.g., fan-cooled vs. non-cooled).

4. 4

   If the motor is hot, allow it to cool down before restarting. Consider increasing acceleration/deceleration times if shock loads are present.
