Overcurrent Error

Hva betyr 08490000 hex ?

The current flowing to the motor exceeded the protection level, indicating an excessive load or electrical fault. This can result in damage to the motor or Servo Drive if not addressed promptly.

• Short-circuit, ground fault, or contact failure on the U, V, or W motor cable.
• Short-circuit on the wiring of External Regeneration Resistor.
• Insulation resistance failed between the U, V, or W motor cable and the motor ground wire.
• False detection due to noise.

1. 1

   Measure insulation resistance between motor phases U-V, V-W, U-W, and each phase to ground using a megger.

2. 2

   Inspect motor cables U, V, W for signs of damage, short circuits, or ground faults.

3. 3

   Check wiring of the External Regeneration Resistor for any short circuits.

4. 4

   Implement noise countermeasures on power and signal lines if noise is suspected.
