9 MAJOR POSITIONING CONTROL
Changing the speed control command speed
In "position-speed switching control", the speed control command speed can be
changed during the position control.
(1) The speed control command speed can be changed during the position control
of position-speed switching control.
A command speed change request will be ignored unless issued during the
position control of the position-speed switching control.
(2) The "new command speed" is stored in " Cd.25 Position-speed switching
control speed change register" by the sequence program during position
control.
This value then becomes the speed control command speed when the
position-speed switching signal turns ON.
