FR-E800 E.PE6 — Fault
Trip — immediate stop
CAUSE
Why does it occur?
This protective function is activated by an inverter reset if writing data fails due to power-OFF or a data fault occurs in the storage device during parameter operations*1 or while the set frequency is written. • Check if the power was turned OFF during parameter operations. • Check if writing to EEPROM is performed frequently.
REMEDY · Step by step
How to fix it?
- • Check the power supply or the devices on the power system to check that the devices have no fault. • When E.PE6 occurs due to power-OFF during parameter operations, take actions according to the read value of Pr.8
- *2 • Set Pr.342 Communication EEPROM write selection = "1" to perform writing to only RAM. Reference manual FR-E800 Instruction Manual (Function) Read value of Pr.890 "7" or lower P
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.).
