my five axis grinder is fitted with a rotary encoder from heidenhain (erm280). Controls are fanuc 160i.
I think we may ve gotten some oil into the encoder area. and were getting following alarms
1. Pulse Miss
2. Over Current etc,
We cleaned the encoder without dismantling it.
The axis tries to find a position as soon as we press the Jog button (when the machine is started). When we press the B Axis button to try to jog it... it is either locked and gives and OVC alarm. or it momentarily rotates at high speed and generated a Axis Excess Error.
any idea of what is causing this.
also how do i clean the area betweent the reader and the ring. The gap is too small. We may have some oil there. But is this the cause.!!!:argue::argue::argue:
