FR-E800 E.EHR — Ethernet communication fault
Trip — immediate stop
CAUSE
Why does it occur?
• Appears when Ethernet communication is interrupted by physical factors while Pr.1431 Ethernet signal loss detection function selection = "3" or Pr.1457 Extended setting for Ethernet signal loss detection function selection = "3". • The inverter output is shut off if Ethernet communication is broken for the time set in Pr.1432 Ethernet communication check time interval or longer for all devices w
REMEDY · Step by step
How to fix it?
- • Check that the Ethernet cable is connected to the Ethernet connector properly and the Ethernet cable is not damaged. • Set a larger value in Pr.14
- • When excessive noise occurs around the inverter, change the communication setting of the master. (The noise may be reduced by setting a shorter timeout period or increasing the number of retries in the communication setting of the master.) • When
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.).
