Parameter Setting Description
4179 #1 1 Uses a MZ sensor
(for the sub spindle side).
4179 #7, 6, 5, 4 Depends on the detector. Sets a position coder signal
(for the sub spindle side).
4180 #4 Depends on the detector. Sets the type of MZ sensor (for
the sub spindle side).
4187 #2, 1, 0 Depends on the detector. Sets a speed detector
(for the sub spindle side).
4177 #2 1 Uses a position coder signal
(for the sub spindle side).
4180 #2 1 Uses a external one rotation
signal (for the sub spindle side).
4180 #3 1 Sets the reverse/unreverse for
a external one rotation signal
(for the sub spindle side).
