Overview of Alarms
SINAMICS-Alarms
Cause: The properties of the DRIVE-CLiQ component (Terminal Module), specified by the fault value, have
changed in an incompatible fashion with respect to the properties when booted. One cause can be,
e.g. that a DRIVE-CLiQ cable or DRIVE-CLiQ component has been replaced.
Fault value (r0949, interpret decimal):
Component number.
Remedy: - when replacing cables, only use cables with the same length as the original cables.
- when replacing components, use the same components and firmware releases.
- carry out a POWER ON.
235899 <location>TM: Unknown fault
Message New message: %1
value:
Drive object: All objects
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: NONE (IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A fault has occurred on the Terminal Module that cannot be interpreted by the Control Unit firmware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Fault value (r0949, interpret decimal):
Fault number.
Note:
If required, the significance of this new fault can be read about in a more recent description of the Con-
trol Unit.
Remedy: - replace the firmware on the Terminal Module by an older firmware version (r0158).
- upgrade the firmware on the Control Unit (r0018).
235903 <location>TM: I2C bus error occurred
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred while accessing the internal I2C bus of the Terminal Module.
Remedy: Replace the Terminal Module.
235904 <location>TM: EEPROM
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred accessing the non-volatile memory on the Terminal Module.
Remedy: Replace the Terminal Module.
235905 <location>TM: Parameter access
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The Control Unit attempted to write an illegal parameter value to the Terminal Module.
Remedy: - check whether the firmware version of the Terminal Module (r0158) matches the firmware version of
Control Unit (r0018).
- if required, replace the Terminal Module.
Note:
The firmware versions that match each other are in the readme.txt file on the memory card.
