Overview of Alarms
SINAMICS-Alarms
Cause: An error has occurred in while accessing via the internal TM I2C bus.
Remedy: Replace the Terminal Module.
234903 <location>VSM: I2C bus error occurred
Message -
value:
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred in while accessing via the internal TM I2C bus.
Remedy: Replace Voltage Sensing Module (VSM).
234904 <location>VSM: EEPROM
Message -
value:
Drive object: CU_CX32, CU_I, CU_LINK, CU_S, HUB, SERVO, TB30, TM15, TM15DI_DO, TM17, TM31, TM41,
TM54F_MA, TM54F_SL, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred accessing the non-volatile memory on the Terminal Module.
Remedy: Replace the Terminal Module.
234904 <location>VSM: EEPROM
Message -
value:
Drive object: A_INF, B_INF, S_INF
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: All objects
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 %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.
