6.2.1 Inputs
The safety input IN1 reacts independent of the operation mode. The low level of IN1 al-
ways enables the safety function. This corresponds with the safety function STO in case
the SS1 time is set to 0 ms. This corresponds with the safety function SS1 in case the
SS1 time is set to >0 ms. The corresponding output OUT1 reacts immediately to the input.
For instance, it can be used at a set SS1 time >0 ms from the master control to initiate a
functional stop of the connected axes before the STO function is enabled after the SS1
time has elapsed.
The safety input IN2 reacts dependent on the mode. The low level of IN2 enables the
safety function only if the operation mode inputs M1 and M2 are low too. This corresponds
with the safety function STO in case the SS1 time is set to 0 ms. This corresponds with
the safety function SS1 in case the SS1 time is set to >0 ms. The corresponding output
OUT2 reacts immediately to the input. For instance, it can be used at a set SS1 time
>0 ms from the master control to initiate a functional stop of the connected axes before
the STO function is enabled after the SS1 time has elapsed.
