IPM Error

What does 04AD0000 hex mean?

The current flowing through the converter exceeded the specified value. This fault indicates an overcurrent condition within the Intelligent Power Module (IPM) of the converter, often caused by similar issues to general overcurrent faults.

• A short-circuit, line-to-ground fault, contact failure, or insulation failure occurred on the U, V, or W motor line.
• The Servo Drive failed.
• The relay for the dynamic brake has been welded due to frequent Servo ON/OFF operations.
• Motor windings are burned out.
• The Servomotor is not suitable for the Servo Drive.
• The pulse input timing is the same as or earlier than the Servo ON timing.

Click steps to track your progress.

1. 1

   Inspect motor power cables for insulation damage, signs of short circuits, and ensure secure connections at both the converter and motor terminals.

2. 2

   Verify converter parameters such as motor rated current, acceleration/deceleration times, and current limits match the connected motor and application requirements.

3. 3

   Measure motor winding resistance and insulation resistance to ground and between phases to detect internal motor faults.

4. 4

   Inspect the mechanical load connected to the motor for binding, obstructions, or excessive friction that could cause overcurrent.

5. 5

   Measure the incoming AC supply voltage at the converter's input terminals to confirm it is stable and within specified operational limits.
