Hi.
Machine model : MS5002E / MOOG Servo Drives Model : DS2110
2021.06.20 IGV Happened F8 fault again in normal operation and IGV locked in around -1.5DEG in 23MW
2019.Nov, 2020.May, 2020.Jun IGV F8 Fault in normal operation and IGV locked in around -1.5DEG
So, I replaced complete IGV system including driver, actuator and resolver cables.
But, IGV driver F8 Fault happened again after 1 year.
From MOOG manual, F8 fault is related to resolver hardware position feedback error and could be caused by resolver cable issue.
But, there were no abnormalities in the resolver cable after inspection.
I replaced all the related equipment(IGV Driver, actuator, resolver cable), but is there reason why the same problem occurs?
Have any of you had a similar experience ?
If the IGV operation is fixed after F8 fault alarm occurs, GTG must be shut down for master reset.
Compressor surge occurs due to IGV locking during GTG shut down.
Damage to the equipment is serious and stable shut down procedure is required when a fault alarm occurs.
best regard.
