STAT : Output the error no in operation
(1) Give “circular Interpolation” command to the axis designated as the axis of positioning module with BASE (Base
no. of Positioning module) and SLOT (Slot no. of Positioning module).
(2) This is the command that execute circular interpolation with main axis set in MST_AXIS and sub axis set in
SLV_AXIS according to operation data set in STEP
(3) Set an axis to command from 0 ~ 1. If you set wrongly, “Error6” arises.
(4) In case STEP is 0, command is executed with current step.
