•Simultaneous start-up instruction (APM_SST) starts the steps of the 2 axes designated in the
instruction simultaneously. For details, see 3.1.7.

(a) Function
•This instruction gives simultaneous start-up reference to the XGB internal positioning.
•At the rising edge of the input condition, the 2 axes of the XGB positioning are started up
simultaneously. See 3.1.7 for the difference between using simultaneous start up instruction and
continuous start up of 2 axes continuously with PLC ladder programming.
•When this instruction is executed, of the XGB’s positioning axes, X and Y axes are simultaneously
started up using the operation data set up at X_STEP and Y_STEP for X-axis and Y-axis,
respectively. Here, since the XGB internal positioning has no Z-axis, the set value of Z_STEP does
not have influence on the operation.
