Siemens SINAMICS S210 - Infeed VSM Count; Precharging Contactor Simultaneity Monitoring Time Exceeded

Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Firmware from version V02.30.01.00 is required when connecting the power units in parallel.
Remedy: Update the firmware of the power units (at least V02.30.01.00).
F05061 Infeed VSM count
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The number of active Voltage Sensing Modules (VSM) for the drive object infeed with chassis power units is not correct.
For A_Infeed, each active power unit must be assigned an active VSM also for a parallel circuit configuration.
For S_Infeed, the active drive object, must be assigned at least one active VSM.
Fault value (r0949, interpret decimal):
Number of VSMs that are currently assigned to the drive object.
Remedy: Adapts the number of active Voltage Sensing Modules (VSM).
F05118 (A) Precharging contactor simultaneity monitoring time exceeded
Message value: fault cause: %1, additional information: %2
Drive object: All objects
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A feedback signal for the precharging contactor (ALM, SLM, BLM diode) or the line contactor (BLM thyristor) interconnected
and the simultaneity monitoring (p0255[4, 6]) activated.
After opening or closing a contactor of the parallel connection, after a monitoring time has elapsed, not all of the contactors
have assumed the same state.
Fault value (r0949, interpret binary):
yyyyxxxx hex: yyyy = supplementary information, xxxx = fault cause
Fault cause:
Bit 0 = 1: simultaneity error when closing the contactors.
Bit 1 = 1: simultaneity error when opening the contactors.
Supplementary information:
Bit 0 = 1: PDS0 contactor is closed.
Bit 1 = 1: PDS1 contactor is closed.
Bit 2 = 1: PDS2 contactor is closed.
Bit 3 = 1: PDS3 contactor is closed.
Bit 4 = 1: PDS4 contactor is closed.
Bit 5 = 1: PDS5 contactor is closed.
Bit 6 = 1: PDS6 contactor is closed.
Bit 7 = 1: PDS7 contactor is closed.
Note:
ALM: Active Line Module
BLM: Basic Line Module
PDS: Power unit Data Set
SLM: Smart Line Module
Remedy: - check the monitoring time setting (p0255[4, 6]).
- check the wiring and control of the contactor.
- if required, replace the contactor.
