Dears,
We have a Vision Wide CNC machine center, and it has the following alarm
Spindle servo alarm No. 750 : spindle serial link error
the spindle servo Amplifier module does not showing any number, just (_ _) is blinking
we checked the following:
the diagnostic parameter 409 bit#1, S1E=1
the parameter 3701 all bits are = zero.
we have checked the fiber optics cables and it has no problem.
any help?
