Control signals by way of terminals on the Control Unit and Motor/Power Module

Features
● Only for the STO, SS1 (time-controlled) and SBC functions
● Dual-channel structure via two digital inputs (Control Unit/power unit)
● A debounce function can be applied to the terminals of the Control Unit and the Motor
● Different terminal blocks depending on the format
● Automatic AND operation of up to 8 digital inputs (p9620[0..7]) on the Control Unit for
Overview of the terminals for safety functions
The different power unit formats have different terminal designations for the inputs of the
safety functions. These are shown in the following table.
