FANUC AC SPINDLE MOTOR a series
2. FUNCTION EXPLANATION
B–65160E/02
90
(c) In case of Series 15
In the rigid tapping, the same parameter address data is used for
the position gain of the tapping axis and the spindle.
Each position gain is selected as follows according to the gear
selection signal (CTH1A, CTH2A) .
