Note
When the Braking Module is in the installed state, the
individual terminals on its X21 terminal
block are positioned as follows: terminal "1" is at the rear, terminal "6" at the front.
Note
Applying a high signal to terminal X21.3 inhibits the Braking Module. On a falling edge,
pending error signals are a
cknowledged.
Note
You will find setting instructions for wiring the signals in the SINAMICS S120 Function
Manual.
