POINT
•
The machine recognizes the presence of a movement amount change request when the data is
written to " Cd.23 Speed-position switching control movement amount change register" with the
sequence program.
•
The new movement amount is validated after execution of the speed-position switching control (INC
mode), before the input of the speed-position switching signal.
•
The movement amount change can be enable/disable with the interlock function in position control
using the “speed-position switching latch flag” ( Md.31 Status: b1) of the axis monitor area.
