Motor Overload

Hva betyr oL1 ?

The motor connected to the drive has been operating under an overload condition, exceeding its thermal limits. This can lead to motor damage or reduced lifespan.

1. 1

   Verify programmed motor nameplate data (e.g., rated current, voltage, frequency) in the Yaskawa P1000 drive parameters (e.g., E1-xx series) against the actual connected motor's nameplate.

2. 2

   Inspect the driven machinery and motor shaft for any mechanical binding, obstructions, or excessive friction that would increase the motor's load.

3. 3

   Inspect motor wiring connections at the drive output terminals (U, V, W) and the motor terminal box for tightness, corrosion, or signs of damage.

4. 4

   Measure the actual motor operating current on each phase using a clamp meter and compare it to the motor's nameplate Full Load Amps (FLA) under typical load conditions.

5. 5

   Check the motor's cooling fan and cooling fins for obstructions or excessive dust buildup to ensure proper thermal dissipation.
