Vsm: I2C Bus Error Occurred; Vsm: Eeprom; Vsm: Parameter Access; Vsm: Temperature Sensor Fault - Siemens Sinamics S120 Diagnostic Manual

234903 <location>VSM: I2C bus error occurred
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred when accessing the module-internal I2C bus.
Remedy: Replace Voltage Sensing Module (VSM).
234904 <location>VSM: EEPROM
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred accessing the non-volatile memory on the Terminal Module.
Remedy: Replace Voltage Sensing Module (VSM).
234905 <location>VSM: Parameter access
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The Control Unit attempted to write an illegal parameter value to the Voltage Sensing Module (VSM).
Remedy: - check whether the firmware version of the VSM (r0158) matches the firmware version of Control Unit (r0018).
- if required, replace the Voltage Sensing Module.
Note:
The firmware versions that match each other are in the readme.txt file on the memory card.
234920 <location>VSM: Temperature sensor fault
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
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: - make sure that the sensor is connected correctly.
- replace the sensor.
