The following table shows setting examples when "2-axis fixed-dimension feed
control (fixed-feed 2)" is set in positioning data No. 1 of axis 1. (The required
values are also set in positioning data No. 1 of axis 2.)

Designate the value set in " Pr.25 Acceleration time 1" as
the acceleration time at start.
Da.4
Deceleration time
No.
0 –
Designate the value set in " Pr.10 Deceleration time 0" as
the deceleration time at deceleration.
