Overview of Alarms
206350 <location>Infeed: Measured line frequency too high
Reaction: NONE
Acknowledge: NONE
Cause: The actual line frequency f_line is higher than the parameterized alarm threshold (f_line >
p0211 * p0284).
The alarm can be output in two operating states:
1. During the power-on phase of the infeed unit.
Consequence:
Synchronization of the infeed to the line supply is interrupted and is restarted.
2. While the infeed is operational.
Consequence:
The infeed remains in the operating (run) state and alarm A6350 is output. This signifies a
critical operational fault.
Alarm value (r2124, floating point):
Actual line frequency determined.
See also: p0284
Remedy: - check the parameterized line frequency and if required change (p0211).
- check the alarm threshold (p0284).
- check the line supply.
- check the line supply quality.

206351 <location>Infeed: Measured line supply frequency too low
Reaction: NONE
Acknowledge: NONE
Cause: The actual line frequency f_line is lower than the parameterized alarm threshold (f_line <
p0211 * p0285).
The alarm can be output in two operating states:
1. During the power-on phase of the infeed unit.
Consequence:
Synchronization of the infeed to the line supply is interrupted and is restarted.
2. While the infeed is operational.
Consequence:
The infeed remains in the operating (run) state and alarm A6351 is output. This signifies a
critical operational fault.
Alarm value (r2124, floating point):
Actual line frequency determined.
See also: p0285
Remedy: - check the parameterized line frequency and if required change (p0211).
- check the alarm threshold (p0285).
- check the line supply.
- check the line supply quality.

206400 <location>Infeed: Line supply data identification selected/active
Reaction: NONE
Acknowledge: NONE
Cause: Line supply data identification selected/active.
The line inductance and the DC link capacitance are measured at the next pulse enable.
See also: p3410
Remedy: No remedial action required.
206500 <location>Infeed: Line synchronization not possible
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
