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.

LED Color Status Description, cause Remedy
- off Electronics power supply is missing or outside permissible
tolerance range.
Component deactivated via terminal.

t monitoring activated.
Ground fault/short-circuit.
Note:
In the event of an overtemperature, the error cannot be
acknowledged until a cooling time has elapsed.
Diagnose fault (via
output terminals) and
acknowledge it (via
input terminal)
- off Electronics power supply is missing or outside permissible
tolerance range.
Component not active.
