Remedy:
- check the parameterized value of the filter capacitance (p0221).
- check the correct wiring of the voltage sensing module (VSM):
Differential voltages u12 and u23 must be present at the 100 V/690 V inputs of the VSM;
the phase currents of the line filter must be connected to the 10 V inputs through a current
- voltage converter.
- check the alarm limits for the permissible filter capacitance deviation (p3676).
- check the normalization of the line supply voltage measurement using the VSM (p3660).
- check the normalization of the filter current measurement using the VSM (p3670).
- check the line filter capacitors and if required, replace the line filter.

206300
<location>Infeed: Line voltage too high at power on
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The RMS line supply voltage Vrms was so high when powering-up that controlled
operation is not possible without exceeding the permissible maximum voltage in the DC
link (p0280).
Fault condition: Vrms * 1.5 > p0280.
Fault value (r0949, floating point):
Lowest possible controlled DC link voltage for the line supply voltage presently connected.
See also: p0280
Remedy:
- check the line supply voltage
- check the maximum DC link voltage and if required, increase (p0280).
- check the line supply voltage and compare with the actual line supply voltage (p0210).
- check whether the power module is dimensioned for the line supply voltage actually being
used.

206301
<location>Infeed: Line overvoltage
Reaction:
NONE
Acknowledge:
NONE
Cause:
The filtered (steady-state) value of the rms line supply voltage Vrms is higher than the
alarm threshold (p0281).
Alarm condition: Vrms < p0281 * p0210.
Alarm value (r2124, floating point):
Actual steady-state line supply voltage.
See also: p0281
Remedy:
- check the line supply.
- check the line supply voltage (p0210).
- check the alarm threshold (p0281).

206310
<location>Infeed: Supply voltage (p0210) incorrectly parameterized
Reaction:
NONE (OFF1, OFF2)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
After pre-charging was completed, the line supply voltage Vrms was calculated using the
measured DC link voltage. This voltage Vrms is not within the tolerance range of the supply
voltage.
The following applies for the tolerance range: 85 % * p0210 < Vrms < 110 % * p0210.
Alarm value (r2124, floating point):
Line supply voltage Vrms present.
See also: p0210
Remedy:
- check the parameterized supply voltage and if required change (p0210).
- check the line supply voltage.
