3 MAJOR POSITIONING CONTROL
3.2 Positioning Data Setting
Movement amount change of the position control
In Speed-position switching control (INC mode), the movement amount of the position control can be changed during the
speed control.
• During the speed control, New movement amount is stored in [Cd.23] Speed-position switching control movement amount
change register using a program. When Speed-position switching signal is turned on, the movement amount of the position
control is stored in [Cd.23] Speed-position switching control movement amount change register.
• At the input timing of Speed-position switching signal, the movement amount of the speed-position switching control
(position control) is stored in [Md.29] Speed-position switching control positioning amount.
• A change request of the movement amount is recognized by writing data into [Cd.23] Speed-position
switching control movement amount change register using a program.
• The timing when the new movement amount becomes valid is from when the speed-position switching
control (INC mode) is performed to when Speed-position switching signal is input.
• By using Speed-position switching latch flag ([Md.31] Status: b1) of the axis monitor area, the movement
amount change can be enabled and disabled using the interlock function in the position control.
