Serial pulse coder

[bigalow]

I experience 350 alarms with serial pulse coders freq. 350 indicates phase problems

Any tips on repairing or aligning the units or a reasonable repair service???

A860-0346-T141. particularly. Lots of failures...Shaft Bearing is almost always bad. Bearing can be changed. But prone to 350 alarms?????? I replace the unit. Fanuc does not repair them. $1100.00 throw away

Aprox 40 Okuma Howa Lathes turning plastic with no coolant.

Alligning that unit is not easy, you'll need as minimum an oscilloscope with the capability to freeze the image of the signal to allign them, they must be 90º one from the other (A,B) there are also more sophisticated equipment like the Heidenhain to do this but it costs about 10k. We have been repairing them at our lab. 50-50 success, try contact tenesee industrial electronics, maybe they can repair it in USA.
