Behaviors when the speed change contact turns ON during acceleration or
deceleration
● A speed change is possible during J-point control, but impossible during acceleration or
deceleration.
● A speed change will be made after the unit goes to constant speed when the speed change
signal turns ON during acceleration or deceleration.
● Specify parameters for the start of operation in the positioning data table. The parameters for
changing speeds are specified in “Channel setting” > “Parameter settings” menu.
● J-point control can be used for single-axis control only. It is not available for interpolation
control.
● Set the unit to increment mode to implement 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.
5.4.7 Programming Cautions

Programming cautions
● The last table should be set to E: End point.
● If any value such as a movement amount, acceleration time, deceleration time or target
speed is out of the specified range, a positioning error will occur when the position control
starts.
● The startup contact and flag numbers vary depending on channel numbers (axis numbers).
