Infeed: Summation Current Impermissibly High; Infeed: Summation Current Too High - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
206210 <location>Infeed: Summation current too high
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The smoothed total of the phase currents (i1 + i2 + i3) is greater than 4 % of the maximum power unit current (r0209).
Possible causes:
- the DC link has a ground fault that results in a high summation current (r0069.6). The DC component in the line cur-
rents can damage/destroy the power unit, line reactor or line filter!
- the zero point calibration of the current measurement was not carried out (p3491, A06602).
- defective current measurement in the power unit.
Fault value (r0949, floating point):
Smoothed total of the phase currents.
Remedy: - check the DC link for a low-ohmic or high-ohmic ground fault and if present, remove.
- increase the monitoring time of the current offset measurement (p3491).
- replace the power unit if necessary.
206211 <location>Infeed: Summation current impermissibly high
Message value: %1
Drive object: AFE_SINUMERIK_828, SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The smoothed sum of the phase currents (i1 + i2 + i3) is impermissibly high. The summation current has exceeded
the assigned ground fault monitoring threshold (p0287).
Possible causes:
- there is a ground fault that results in a high summation current (r0069.6). The DC component in the line currents can
damage/destroy the power unit, line reactor or line filter!
- the zero point calibration of the current measurement was not carried out (p3491, A06602).
- defective current measurement in the power unit.
Fault value (r0949, floating point):
Smoothed total of the phase currents.
Remedy: - check the line supply for ground faults and remove any that are present.
- check the set ground fault monitoring threshold (p0287).
- replace the power unit if necessary.
206215 <location>Infeed: Summation current too high
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The smoothed total of the phase currents (i1 + i2 + i3) is greater than 3 % of the maximum power unit current (r0209).
Possible causes:
- the DC link has a ground fault that results in a high summation current (r0069.6). The DC component in the line cur-
rents can damage/destroy the power unit, line reactor or line filter!
- the zero point calibration of the current measurement was not carried out (p3491, A06602).
- defective current measurement in the power unit.
Alarm value (r2124, floating point):
Smoothed total of the phase currents.
Remedy: - check the DC link for a low-ohmic or high-ohmic ground fault and if present, remove.
- increase the monitoring time of the current offset measurement (p3491).
- replace the power unit if necessary.
