Cause
Loose connection in spindle, spindle
cable or at the connectors
Disturbances on the signal or the
signal amplitude is too low
> sensor wires in spindle cable are
not shielded
Spindle cable is defective
Spindle cable too long
With activated spindle test, a test
current is send via spindle cable to the
spindle by applying a voltage at output
lines. In case that this current is too
low, or a wrong spindle characteristic
selected, it does not match to the
reference values and the spindle test
fails.
