Trip — immediate stop
CAUSE
Why does it occur?
- DC circuit voltage exceeds prescribed amount
- Short deceleration time, regenerative load, high supply voltage
REMEDY · Step by step
How to fix it?
- Increase deceleration time
- Use braking resistance device
- Check supply voltage
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.).
