7.15.2.8 Checking the interconnection of digital inputs
Overview
The simultaneous connection of digital inputs with a safety function and a "standard" function
may lead to the drive behaving in unexpected ways.
If you control the safety functions in the converter via fail-safe digital inputs, then you must
check as to whether the fail-safe digital inputs are in some instances interconnected with a
"standard" function.
