Inverter Overheat

What does 6 mean?

This alarm indicates an overheat condition within the Inverter (Servo Amplifier). Potential causes include motor overload, inadequate cabinet cooling, high ambient temperature, or improper seating of the control printed-circuit board, all of which can lead to thermal stress on the amplifier.

• Motor operation exceeding its continuous rating.
• Insufficient cooling capacity within the cabinet (e.g., clogged filters, failed fans).
• Ambient temperature exceeding operational limits.
• Faceplate (control printed-circuit board) not fully seated.

1. 1

   Check that the motor is being used at or below its continuous rating.

2. 2

   Inspect the cabinet cooling fans and filters to ensure sufficient cooling capacity.

3. 3

   Verify that the ambient temperature is within acceptable operating limits.

4. 4

   Ensure the faceplate (control printed-circuit board) is pushed in as far as it will go.

5. 5

   Replace the Servo Amplifier if all other checks are satisfactory.
