Unusual F26

Gary.Hare Posts: 101 Rating: (8)	We have a Mastrdrive CUVC which is throwing up a sporadic (0.5 - 25 hours) F26. Work done so far and the fault still occurrs:- Drive replaced with new, Drive swapped with a known working drive, CU card replaced, Drive run with L1 - 3 disconnected so no load on drive (eliminating earth fault on cabling/motor), STO shorted out,so basically all the usual suspects have been eliminated yet this dam fault keeps coming!!! Anyone know of any external factors that could cause such an issue?
