Hello,
A friends cat ep20kt throws error e28 if you try to move forward. Driving backwards and hydrolic works fine.
E28 is phase error sensor
Could you please advise me what to check/measure to trace the reason for this error ??
Kind regards from the Netherlands,
Eric

Thanks for your reply! Appreciate it!
Yesterday I already measured the H board and found one of the Fet's was faulty indeed. (fet for switching left motor winding)
Waiting for parts now, it's a p60nf10 FET and I will try my luck after replacing it. Other parts on H board measure okay (lso measured the cables to the motors and the windings).
Kind regards,
Eric
it is a shorted/faulty H bridge board i mean. Try a new one and look it is solved.
Nobody?
A little help how to measure/test the H board or motor windings would be appreciated......
Kind regards,
Eric
