J-Point Control (Jog Positioning: Speed Changes) - Panasonic FP7 User Manual

10.10.6 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 positioning
parameters 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.

Operations of each contact
● The BUSY flags (X30, X31) will turn on when the operation starts and turn off when the
operation is completed.
● The operation done flags (X34, X35) will turn on when the JOG operation is completed, and
it will be held until the next positiotning control, JOG operation, or home return operation
starts.
● The target speed will be changed when the J-point control speed change flags (Y54, Y55)
turn on. 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 control will
not be performed.

Characteristics of acceleration/deceleration zone when changing speeds
● The speed of speed change zone changes by approx. 100 us when changing the speed in
the J-point control. The speed variation is obtained by the following formula.
