When compensation of the feedback signal of the motor sensor
connected to spindle amplifier JYA2 is performed, the settings of
parameter Nos. 4355 and 4356 are adjusted. When compensation of
the feedback signal of the spindle sensor connected to JYA4 is
performed, the settings of parameter Nos. 4357 and 4358 are adjusted.
When as with a built-in motor the speed sensor and position sensor are
the same (the feedback signal of JYA2 is used for speed detection and
position detection), compensation is performed for JYA2 only. When
the speed sensor and position sensor are provided separately (the
feedback signal of JYA2 is used for speed detection, and the feedback
signal of JYA4 is used for position detection), compensation is
performed for both JYA2 and JYA4.
