My Yaskawa A1000 drive is makes my 3-phase motor continuously pulsate? Motor is attached to a ZUN table cutting.

0
1 comments:
Mr. Anderson
March 20, 2025

A Yaskawa A1000 drive causing a 3-phase motor to pulsate continuously when connected to a ZUN table cutting could be due to several factors:

1. Output Current Imbalance (LF2 Fault) – If one or more motor phases experience a current imbalance, the motor may not run smoothly. Check for:
- Faulty wiring or poor connections on the output side.
- Loose terminal wires; ensure they are tightened to the specified torque.

2. Auto-Tuning Not Performed – The drive may not have the correct motor parameters. Perform auto-tuning to set proper motor characteristics.

3. Incorrect Motor Control Mode – If using a Permanent Magnet (PM) motor, ensure the correct control mode is selected. Note that PM motor control is not available for 600V class drives.

4. Drive Overload Due to Repetitive Starting/Stopping – If the table cutting application involves frequent starts and stops, the drive might be experiencing excessive heat stress. Try:
- Lowering the carrier frequency.
- Reducing load or increasing acceleration/deceleration times.
- Using a larger drive if peak current exceeds 150% of the rated value.

Check these factors and make necessary adjustments to improve motor operation.
