5.4 Positioning Control
5.4.5 J-point Control (JOG Positioning)
● The parameters for position control operations are specified in the positioning parameter
setting menus and data tables of Configurator PMX.
● When the positioning table start instruction (F380 POSST) or positioning simultaneous start
instruction (F383 MPOST) is executed, the pulse output will start. In the J-point control, the
unit operates at a target speed after the startup, and will start the position control when the J-
point positioning start contacts (X0 and X1) turn ON.
● In the system register no. 400, select "J-point positioning start input of pulse output CH*" of the
channel to perform the J-point control.
