8. Spindle Parameters
8.3 MDS-B-SP/SPH, MDS-C1-SP/SPH
This parameter is used for adjustment of
orientation operation of the magnetic sensor.
Set the distance dimension from the target stop
point at switching from position feedback to
magnetic sensor output.
Normally, set a value that is approx. 1/2 of the
value defined in SP124.
Use not possible.
Set the C-axis specifications in bit units.
