Inrush current of approximately 1.5 A flows instantaneously when turning the control circuit power supply on. Select an
appropriate capacity of power supply considering the inrush current.
Power-on duration of the safety logic unit is 100,000 times.
_: in signal name indicates a number or axis name.
This function diagnoses malfunction of contacts including an external circuit by shortly turning off signals from a controller to
the servo amplifier at a constant period while input signals of the servo amplifier are on.
