SINAMICS DCM
1150 List Manual (LH8), 02/2015, 6RX1800-0ED76
F60044 (N, A) Parallel interface node failure
Message value: %1
Message class: Communication error to the higher-level control system (9)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A fault involving the parallel connection of power units has occurred.
Fault value (r0949, interpret decimal):
1: There is a fault on one of the slaves.
2: One of the slaves is not in the Operation state (e.g. because its enable signal is at "0")
3: There are fewer power units connected in parallel that are active than set using p51802.
4: There are fewer devices that are active than set using p51815.
50: The switchover to power unit topology 2 is not possible, as this SINAMICS DCM is not equipped with option S50.
51: The switchover to power unit topology 2 is not permissible for "n+m" operation.
52: The parallel switching master in power unit topology 2 is not the same as in power unit topology 1.
53: The feedback indicating the active power unit topology does not match the selected power unit topology.
Remedy: - Check the slave with fault.
- Check the enable signal of the slaves
- Check the setting for the minimum number of devices (p51802, p51815).
- Check the parameterization of the switchover of the power unit topology.

F60045 (N, A) Standstill field not permitted in operation
Message value: -
Message class: Power electronics faulted (5)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The standstill field was activated while the drive was operational.
The binector input p50692 to activate the standstill field must not have a 1 signal in operation.
See also: p50692 (Cl-loop field curr ctrl sig source for inject of standst field)
Remedy: If required, set binary input p50692 - used to activate the standstill field - to a 0 signal.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F60046 (N, A) Wire break at "Main setpoint" analog input
Message value: -
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A wire break has been detected at the CUD's "Main setpoint" analog input (X177.25/26).
This fault is triggered if p50700 = 2 (unipolar monitoring of current input (+4 mA to +20 mA)) is set and an input
current of less than 2 mA is flowing.
Possible fault causes:
- Wire break or contact problem on supply line
- Parameter p50700 set incorrectly
