3.7.4 Reference Signal for the Spindle
Usually, the reference mark of the spindle encoder is evaluated as a reference signal for the spindle.
In special cases, a 24 V signal on terminal X30 can be evaluated as a reference signal for the spindle
or as a reference signal release (see chapter “Spindle”). For reliable evaluation, the signal must last
for at least 3 milliseconds.
