5-3-4. Specification Limitation
When you use this control, be careful for the followings.
(1) When the spindle speed under variation control exceeds the maximum spindle speed (including
maximum spindle speed command), the speed hits the peak at the maximum spindle speed. Be
careful of this matter sufficiently when you give a command.
(2) Do not use this control if the variation of spindle speed gives troubles to cutting.
(Ex.)
•
Tapping
•
Flat-turning (M220 to M226)
(3) This control is not effective for spindle rotation other than spindle forward rotation (M03) and
spindle reverse rotation (M04).
(Ex.)
•
Spindle orientation command (M19)
•
Spindle inching command
•
Synchronous rotation control (M151)
(4) Even for spindle forward rotation (M03) or spindle reverse rotation (M04), this control is not
effective in the following condition.
(Ex.)
•
During constant peripheral speed control (G96)
(5) If the relationship between spindle speed variation cycle (P) and interval timer (R) is as shown
below, spindle speed variation control cannot be applied. Be careful of this matter sufficiently
when you set data.
Spindle speed variation cycle (P) ≤ Interval timer (R) × 2
