7.1.5 Setting and Operation of J-point Control
• JOG positioning (J-point) control operates at target speed until the start contact of J-point
positioning turns ON after the operation of the positioning unit starts, and the next positioning
control will start when the start contact of J-point positioning turns ON.

• Specify parameters for the start of operation in the positioning data table.
Specify parameters in the axis parameter-setting menu at the time of speed
change.
• J-point control can be used for single-axis control only. It is not available
for interpolation control.
• Set the positioning unit to increment mode to implement P-point control, C-
point control, or E-point control with positions specified after J-point
control is implemented.
• Speed control is performed while the positioning unit is in J-point control,
in which case, be sure to input the amount of movement for positioning with
a value that can secure a target constant-speed area.
