S300 BX — BX
Trip — immediate stop
CAUSE
Why does it occur?
- Cuts off the inverter output according to the multifunction terminal function setting
- It operates when DIN-01, 03, 05, 07, 09, 11, 13, 15 (DI1-DI8 Define) code is set to 4 (BX)
REMEDY · Step by step
How to fix it?
- Check whether the DIN-01, 03, 05, 07, 09, 11, 13, 15 parameter is set to 4 (BX)
- Reset after releasing the external BX signal
- If the setting was unintended, change that terminal's function to a different value
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.).
