FR-E800 E.CMB — Board mismatch
Trip — immediate stop
CAUSE
Why does it occur?
- Appears when the combination of the inverter and its circuit board is not appropriate, or when the circuit board with the control circuit terminal block is not connected to the inverter
- Check that the circuit board with the control circuit terminal block is connected to the inverter
REMEDY · Step by step
How to fix it?
• Connect the circuit board with the control circuit terminal block to the inverter. (Tightening torque when the circuit board is connected to the inverter: 0.33 to 0.40 N·m) • Contact your sales representative.
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.).
