- 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
Inspect the driven machinery and motor shaft for any mechanical binding, obstructions, or excessive friction that would increase the motor's load.
- 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
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
Check the motor's cooling fan and cooling fins for obstructions or excessive dust buildup to ensure proper thermal dissipation.
