MR-JE AL.E0 — Excessive regenerative warning
Warning — monitor
CAUSE
Why does it occur?
- Regenerative load ratio exceeded 85% of the alarm level
- Regenerative energy is too high for the built-in resistor
REMEDY · Step by step
How to fix it?
- Review the duty cycle and deceleration time
- Add an external regenerative resistor if necessary
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
