FR-E800 E.IOH — Inrush overheat
Trip — immediate stop
CAUSE
Why does it occur?
- The inverter output is shut off when the resistor of the inrush current limit circuit is overheated
- The inrush current limit circuit is faulty. • Check that frequent power ON/OFF is not repeated. • Check if the input side fuse (5A) in the power supply circuit of the inrush current limit circuit contactor is blown. • Check that the power supply circuit of inrush current limit circuit contactor is
REMEDY · Step by step
How to fix it?
- Configure a circuit where frequent power ON/OFF is not repeated
- If the problem still persists after taking the above measure, contact your sales representative
- Reference manual FR-E800 Instruction Manual (Function)
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.).
