Parameter Setting Description
4018#4 1 Uses the a sensor Cs contouring control
function.
4001#2 1 Uses a position coder signal.
4001#5 0 Does not use a high–resolution magnetic
pulse coder.
4001#6 0 Specifies that a position detection signal
for Cs contouring control is not used for
speed detection.
4003#1 1 Uses an MZ sensor or BZ sensor.
4003#7,6,5,4 Depends on
the detector.
Sets a position coder signal.
4004#1 1 Uses a separate position detector.
4004#4 0 Sets a one–rotation signal type.
4011#2,1,0 Depends on
the detector.
Sets a speed detector type.
(c) If an MZ sensor is used on the motor–side with the a position
coder S on the spindle side
