The following alarm is intermittent but very persistent;
7226 SPN 2 ISCONNECT C-VELO DETECT
This alarm has plagued me for a year ( maybe longer I have only been with this shop for a little over a year ). I have inspected and cleaned the sensor and reluctor on the sub spindle.
It appears that this situation has has been a problem for several years on this machine. Last year the sub-spindle sensor was replaced, I think that it's the sixth time this sensor to be replaced on the sub spindle.
The alarm will happen when the sub spindle is commanded to spin and when E-axis is moving and when E-axis is not moving.
It happens when running in automatic mode or when being jogged manually ( sub spindle spinning and jogging E-axis at the same time )
But the biggest headache is that it doesn't alarm out every time consistently.
The machine may run through 8 or so cycles then alarm out, sometimes it won't make it through 1 cycle then alarm out.
I'm talking with a Morris South tech. and waiting for him to call me back but maybe one of you Hardinge gurus can help me out.
Thanks in advance.
