Alarm #102 sevos off. #172 phase loss L3 - L1 and over heat. I can only clear the over heat alarm if I unplug the wire # 380 over heat from the board.
The 102 servos off and 172 phase loss L3 – L1 will not clear.
Dose any one know how to fix this old girl?
do you have all three phases on the machine what voltage are you runnning? there is a parameter to turn off phase detect but you have to make sure that you have all three legs get a meter and check incoming voltage on all 3 phases if you have good voltage between l1 to l2 l2 to l3 and l1 to l3 then you can turn off the parameter for phase loss it is in one of the common pages either parameter 57 209 or 278 ph loss det somethin like that.
Thanks! I'll check it out.
It was paramater 57.
WA WHOW!
