Braking Module Internal Overtemperature; Braking Module Internal Shutdown Due To Overtemperature; Braking Module Internal Vce Fault - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
206907 <location>Braking Module internal overtemperature
Message value: -
Drive object: BIC_SINUMERIK_828
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The temperature sensor connected to the braking resistor signals an overtemperature.
The Braking Module is still active. If the overtemperature persists for more than 60 s, fault F06908 is output, and the
braking module is switched off.
See also: r3687 (Digital Braking Module pre-alarm overtemperature)
Remedy: - reduce the temperature at the sensor.
- check the temperature sensor connection.
206908 <location>Braking Module internal shutdown due to overtemperature
Message value: -
Drive object: BIC_SINUMERIK_828
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: Braking module shut down due to overtemperature at the temperature sensor of the braking resistor.
The overtemperature is detected by the sensor for longer than 60 s.
See also: r3688 (Digital Braking Module fault overtemperature)
Remedy: - reduce the temperature at the sensor.
- check the temperature sensor connection.

Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Trip due to Vce fault. Collector emitter voltage dip (Vce)
See also: r3689 (Digital Braking Module Vce fault)
Remedy: - Power ON
- replace the unit.
