Possible Causes
Electrical noise on control lines, Faulty speed sensor, Loose control wiring, Software glitch
How to Fix / Troubleshooting
Safety first: Turn off power before accessing control wiring or the drive module.
Steps to stabilize speed:
- Check control wiring: Inspect low-voltage control and feedback cables for loose connections or damage.
- Isolate from automation: Temporarily disconnect external control and run the pump in standalone mode.
- Factory reset: Reset the drive parameters and reprogram speeds.
- Monitor operation: If speed still oscillates, the speed sensor or drive module may be failing.
Persistent unstable speed typically requires replacement of the motor (with integrated sensor) or drive module.
