Figure 80 - Single-axis Relay Configuration (Stop Category 1) with Automatic Reset
(1) The digital input, configured for Abort Index in MotionView software, must be active-high when the safety function is requested, so
an interposing relay may be required to invert the signal. Digital input common (IN_x_COM) must be used in this signal activation/
de-activation transition.
You can also bring this input into a PLC where you can use an AOP (add on profile) or assembly object to activate the recommended
digital input (abort index).
