10.10 Positioning Control10-5710.10.6 J-point Control (JOG Positioning: Speed Changes)• In the J-point control, the speed can be changed while controlling the speed after the start.• After starting the J-point control, the unit operates at the speed specified in the positioningparameters of Configurator PMX.• The speed changes when the J-point control speed change flag (Y54, Y55) turns on.• For J-point control, only "Increment" can be used as a control method.

The change will be enabled at the edge where the contact turns on.• Positioning control will start when J-point control positioning start inputs (X1, X5 or Y50, Y51)turn on. However, when the inputs (X1, X5) are used as near home inputs, J-point controlwill not be performed.
