Drive Overload

Hva betyr oL2 ?

The drive itself has been operating under an overload condition, exceeding its continuous current rating. This can lead to drive shutdown or damage if not addressed.

1. 1

   Verify the mechanical load on the motor for any binding, obstruction, or excessive resistance that could lead to increased current draw.

2. 2

   Check drive parameters P2-01 (Motor Rated Current) and P6-01 (Overload Selection) against the motor nameplate data and application requirements.

3. 3

   Inspect motor power cables (U, V, W) for proper termination, insulation integrity, and signs of damage or short circuits between phases or to ground.

4. 4

   Monitor the drive's output current display and, if safely possible, independently measure motor phase currents to verify actual load against the motor's Full Load Amps (FLA).
