Overcurrent Error

What does 08490000 mean?

The current drawn by the motor has surpassed a predetermined protection threshold, indicating an excessive load or electrical anomaly within the motor or its wiring. This can cause damage to the motor or drive.

• Short-circuit, ground fault, or contact failure on motor cables U, V, or W
• Short-circuit on the wiring of the External Regeneration Resistor
• Insulation breakdown between motor cables U, V, W and motor ground wire
• False overcurrent detection due to electrical noise
• Internal Servo Drive failure

Click steps to track your progress.

1. 1

   Measure insulation resistance between motor phases U-V, V-W, U-W, and between each phase (U, V, W) and motor ground. Expect values >1 MΩ.

2. 2

   Visually inspect motor cables U, V, W and their connections for signs of short-circuit, ground fault, or contact failure.

3. 3

   Inspect the wiring of the External Regeneration Resistor for any short-circuits.

4. 4

   Verify proper grounding and shielding of the Servo Drive and motor cables to mitigate noise.
