(7) Changing the speed control command speed
In "position-speed switching control", the speed control command speed can be changed during the position
control.
• 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.
• The "new command speed" is stored in "[Cd.25] Position-speed switching control speed change register" by
the program during position control. This value then becomes the speed control command speed when the
position-speed switching signal turns ON.

● The machine recognizes the presence of a command speed change request when the data is written to "[Cd.25] Position-
speed switching control speed change register" with the program.
● The new command speed is validated after execution of the position-speed switching control before the input of the
position-speed switching signal.
● The command speed change can be enabled/disabled with the interlock function in speed control using the "position-
speed switching latch flag" ([Md.31] Status: b5) of the axis monitor area.
