Troubleshooting Steps
- Step 1: Check the speed command source for values exceeding the limit
Speed command is within the configured limit - Step 2: Verify the speed limit parameter is set correctly for the motor
Speed limit matches the motor rated speed - Step 3: Adjust the analog reference scaling if the input exceeds range
Analog reference is scaled to the correct range
