Overview of Alarms
SINAMICS-Alarms
235920 <location>TM: Temperature sensor fault
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, interpret decimal):
1: Wire breakage or sensor not connected (KTY: R > 1630 Ohm).
2: Measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm).
Remedy: - check that the sensor is connected correctly.
- replace sensor.
235999 <location>TM: Unknown alarm
Message New message: %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An alarm has occurred on the Terminal Module that cannot be interpreted by the Control Unit firm-
ware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Alarm value (r2124, interpret decimal):
Alarm number.
Note:
If required, the significance of this new alarm can be read about in a more recent description of the
Control Unit.
Remedy: - replace the firmware on the Terminal Module by an older firmware version (r0158).
- upgrade the firmware on the Control Unit (r0018).
236207 <location>Hub: Overtemperature component
Message %1
value:
Drive object: A_INF, B_INF, HUB, S_INF, SERVO, TM41, VECTOR
Reaction: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Temperature on DRIVE-CLiQ Hub Module has exceeded fault threshold.
Fault value (r0949, interpret decimal):
Current temperature in 0.1°C resolution.
Remedy: - Check ambient temperature at component installation location.
- replace the component involved.
236211 <location>Hub: Overtemperature alarm component
Message %1
value:
Drive object: A_INF, B_INF, HUB, S_INF, SERVO, TM41, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: Temperature on DRIVE-CLiQ Hub Module has exceeded alarm threshold.
Alarm value (r2124, interpret decimal):
Current temperature in 0.1°C resolution.
Remedy: - Check ambient temperature at component installation location.
- replace the component involved.
