9. SPINDLE FUNCTIONS
B–63522EN/02
NC FUNCTION
122
The advanced feedforward control function can be made usable for serial
interface spindles. This makes rigid tapping, Cs contour axis control (for
the first axis only), and spindle positioning (T series) usable even in the
advanced control mode.
Because the fine acceleration/deceleration (FAD) function cannot be
applied to the serial interface spindle, however, it cannot be used for the
servo axis if advanced control is applied to the serial interface spindle.
Appropriate parameter setting causes the current position coder position
(the number of pluses) to be displayed with a precision of 4096 per
rotation on the diagnosis screen.
This data can be used to determine the current position of the spindle.
