Notes: 1. Inrush current of approximately 1.5mA flows instantaneously when turning the control circuit power supply on. Select an appropriate
capacity of a power supply considering the inrush current.
2. Power-ON duration of the safety logic unit is 100,000 times.
3.  in signal name represents a symbol which indicates a system number and axis name.
