A06105 (F)
Infeed: Line supply undervoltage
Drive object:
A_INF, B_INF, S_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
The filtered (steady-state) value of line supply voltage is lower than the alarm threshold (p0282).
Alarm condition: Vrms < p0282 * p0210
Alarm value (r2124, floating point):
Actual steady-state line supply voltage.
See also: p0282 (Line supply undervoltage, alarm threshold)
Remedy:
- check the line supply.
- check the line supply voltage (p0210).
- check the alarm threshold (p0282).
Reaction upon F:
NONE (OFF1, OFF2)
Acknowl. upon F:
IMMEDIATELY (POWER ON)
F06200
Infeed: Failure of one or several line phases
Drive object:
A_INF, B_INF, S_INF
Reaction:
OFF2 (OFF1)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
Failure of one or several line phases.
The fault can be output in two operating states:
1. During the power-on phase of the infeed unit.
The measured line supply angle deviates from the regular characteristic for a 3-phase system - the PLL cannot be
synchronized.
The fault occurs immediately after power-up if, when operating with a VSM, the phase assignment L1, L2, L3 at the
VSM differs from the phase assignment at the power unit.
2. While the infeed is operational.
After a voltage dip has been detected (note A06205) in one or several line phases a fault occurred within 100 ms
(also refer to other relevant messages).
Probable causes of the fault:
- voltage dip on the line side or phase phase failure lasting longer than 10 ms.
- overload condition on the load side with peak current.
- commutating reactor missing.
Remedy:
- check the line supply and fuses.
- check the connection and size (rating) of the line commutating reactor.
- check and correct the phase assignment at the VSM and at the power unit.
- check the load.
- if failed in operation, carefully note the previous alarm messages A6205 with alarm values.

A06205 (F)
Infeed: Voltage dip in at least one line supply phase
Drive object:
A_INF, B_INF, S_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
Voltage dip or overvoltage in one or several line supply phases has been detected in operation.
The pulses are then canceled for a time of at least 8 ms. The operating signal of the infeed unit in r0863.0 remains
and the pulse inhibit due to the phase failure is displayed in r3405.2.
Alarm value (r2124, bitwise coded cause of the alarm):
Bit 0: Line angle deviation (limit value p3463) due to a line supply fault
Bit 2: Active current deviation
Bit 3: Line frequency deviation (limit values: 115 % * p0284, 85 % * p0285)
Bit 4: Line overvoltage (limit value130 % * p0281)
Bit 5: Line undervoltage (limit value 20 % * p0210)
Bit 7: Peak current fault
Bit 8: Smart Mode without VSM (p3400.5 = 0): Line angle deviation
Bit 9: Smart Mode: DC link voltage dip
