S300 Reset Restart Fail — Reset Restart Fail
Trip — immediate stop
CAUSE
Why does it occur?
Occurs when the reset-and-restart function operates due to exceeding the set retry count.
REMEDY · Step by step
How to fix it?
- The retry count in parameter PRT06 can be adjusted up to a maximum of 10 times; if it occurs more than 10 times, it is not a trip-reset condition
- Check the trip content
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.).
