Changing the command speed of the speed control
In Position-speed switching control, the command speed of the speed control can be changed during the position control.
• When the command speed change is requested during the control other than the position control of the position-speed
switching control, the change request is ignored.
• During the position control, New command speed is stored in [Cd.25] Position-speed switching control speed change
register using a program. When Position-speed switching signal is turned on, the setting of [Cd.25] Position-speed
switching control speed change register becomes the command speed of the speed control.
• A change request of the command speed is recognized by writing data into [Cd.25] Position-speed
switching control speed change register using a program.
• The timing when the new command speed becomes valid is from when the position-speed switching control
is performed to when Position-speed switching signal is input.
• By using Position-speed switching latch flag ([Md.31] Status: b5) of the axis monitor area, the speed change
can be enabled and disabled using the interlock function in the speed control.
