Meaning Of The Leds On The Braking Module - Siemens SINAMICS S120 Equipment Manual

Note
Applying a high signal to terminal X21.1 inhibits the Braking Module. On a falling edge,
pending error signals are acknowledged.
The pre-warning for I*t monitoring is output as a high level on reaching 80% of the maximum
braking resistor ON time.
Only braking resistors approved by Siemens for this component are identified automatically.
