Overcurrent: Short in Powerstage

What does F860 mean?

This is a fatal error indicating an internal short circuit within the ECODRIVE DKC01.1/DKC11.1 drive's power stage, leading to excessive current flow. This fault immediately causes the drive to shut down to prevent further damage.

• Internal failure of power semiconductor components (e.g., IGBTs) within the drive.
• Motor winding short circuit or insulation breakdown causing high current demand.
• Short circuit in motor cables or connection points (e.g., terminal box).
• Severe mechanical overload or sudden jam causing excessive motor current.

Click steps to track your progress.

1. 1

   Disconnect motor power cables from the ECODRIVE DKC01.1/DKC11.1 drive and check for short circuits between motor phases and to ground using a megohmmeter.

2. 2

   Inspect the motor and load for any mechanical binding, obstructions, or excessive load that could cause extreme current.

3. 3

   Verify motor winding integrity by measuring resistance between phases and insulation resistance to ground.

4. 4

   If external checks are clear and the fault persists, it indicates an internal power stage failure; the ECODRIVE DKC01.1/DKC11.1 drive controller must be exchanged.
