The positioning window from MP7150 is effective for the tool axis while Cycle 17 is being run. The
input value must be less than or equal to MP1030.x. You define the spindle acceleration and
deceleration process in MP3410.3, MP7130 and MP7140. Spindle overshoot is to be avoided during
acceleration and approach.

Cycle 18
With Cycle 18 the tool axis tracks the actual position of the spindle. The starting position is the
current position. The target position is the total hole depth. Approaching and departing movements
must be programmed separately. During Cycle 18 marker M2095 is set. M2499 must be reset so
that the cycle is run. MP7130, MP7140 and MP7150 have the same function as for Cycle 17.
