4.2 List of faults and alarms
F30903 Power unit: I2C bus error occurred
Message value: %1
Message class: Hardware / software error (1)
Drive object: B_INF, VECTOR_G
Reaction: Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY
Cause: Communications error with an EEPROM or A/D converter.
Fault value (r0949, interpret hexadecimal):
80000000 hex:
- internal software error.
00000001 hex ... 0000FFFF hex:
- module fault.
Remedy: Re fault value = 80000000 hex:
- upgrade firmware to later version.
Re fault value = 00000001 hex ... 0000FFFF hex:
- replace the module.
F30907 Power unit: FPGA configuration unsuccessful
Message value: -
Message class: Hardware / software error (1)
Drive object: B_INF
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: During initialization within the power unit, an internal software error has occurred.
Remedy: - if required, upgrade the firmware in the power unit.
- replace power unit.
- contact the Hotline.
A30920 (F) Power unit: Temperature sensor fault
Message value: %1
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
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, PT100: R > 375 Ohm).
2: Measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm, PT100: R < 30 Ohm).
Note:
A temperature sensor is connected to the following terminals:
- "Booksize" format: X21.1/.2 or X22.1/.2
- "Chassis" format: X41.4/.3
Information on temperature sensors is provided in the following literature for example:
SINAMICS S120 Function Manual Drive Functions
Remedy: - make sure that the sensor is connected correctly.
- replace the sensor.
Reaction upon F: Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY
