Changing the speed control command speed
In "position-speed switching control", the speed control command speed can be

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.

control speed change register" by the sequence program during position
control.
This value then becomes the speed control command speed when the
