Overview of Alarms
SINAMICS-Alarms
205059 <location>Parallel circuit: VSM firmware versions differ
Message Parameter: %1
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The firmware versions of the Voltage Sensing Module (VSM) do not match.
Fault value (r0949, interpret decimal):
Parameter in which the first different version number was detected.
Remedy: For parallel circuit configurations, only Voltage Sensing Modules (VSM) with identical firmware ver-
sions may be used.
205060 <location>Parallel circuit: Power unit firmware version does not match
Message Parameter: %1
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
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).
205061 <location>Infeed, number of VSM
Message %1
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
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 con-
figuration.
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).
206000 <location>Infeed: Precharging monitoring time expired
Message -
value:
Drive object: A_INF, B_INF, S_INF
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: After the line contactor closes the power unit does not signal the READY state within the monitoring
time (p0857).
The end of the DC link pre-charging was not able to be completed for one of the following reasons:
1) There is no line supply voltage connected.
2) The line contactor/line side switch has not been closed.
3) The line supply voltage is too low.
4) Line supply voltage incorrectly set (p0210).
5) The pre-charging resistors are overheated as there were too many pre-charging operations per
time unit.
6) The pre-charging resistors are overheated as the DC link capacitance is too high.
7) The pre-charging resistors are overheated because when there is no "ready for operation" (r0863.0)
of the infeed unit, power is taken from the DC link.
8) The pre-charging resistors are overheated as the line contactor was closed during the DC link fast
discharge through the Braking Module.
9) The DC link has either a ground fault or a short-circuit.
10) The pre-charging circuit is possibly defective (only for chassis units).
