(c) Operation of the Program
• SST instruction is executed it the rising edge of M0001, which was used as the instruction signal of
the simultaneous starting is generated.
1) If the simultaneous starting instruction (SST) is executed, the two axes are simultaneously
started as set in the operand as follows.
2) Since sl is 0, built-in positioning of the basic unit operates simultaneous starting.
3) If the set value of ax does not exceed the setting range, it does not affect the operation.
4) Since the step numbers of axis X and axis Y are set 1 and 2 respectively, the two axes are
simultaneously started by using the operation data of the operation step.
5) Since there is no axis Z in XGB built-in positioning, even if a random value is input as the step
number of axis Z operation, the operation is not affected.
