5.6 Control via terminals on the Control Unit and Motor/Power Module
5.6.1

Features

● Control via terminals is only available for Basic Functions.
● Dual-channel structure via 2 digital inputs (Control Unit/power unit)
● In order to prevent nuisance trips as a result of signal disturbances or non-symmetrical test
signals, the signals can be debounced at the terminals of the connected components
(pushbuttons, switches etc.).
You can specify these debounce times in the following parameters:
– p9651 SI STO/SBC/SS1 debounce time (Control Unit) / SI STO t_debou CU
– p9851 SI STO/SBC/SS1 debounce time (Motor Module) / SI STO t_debou MM
● Different terminal blocks depending on the format.
● Automatic ANDing of up to 8 digital inputs (p9620[0...7]) on the Control Unit with parallel
configuration of power units in the chassis format is not supported.
