Infeed: Measured Line Frequency Too High; Infeed: Measured Line Frequency Too Low - Siemens Sinamics S120 Diagnostic Manual

206350 <location>Infeed: Measured line frequency too high
Message value: Line frequency: %1
Drive object: AFE_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
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 (Line supply frequency exceeded, alarm threshold)
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 frequency too low
Message value: Line frequency: %1
Drive object: AFE_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
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 A06351 is output. This signifies a critical operational fault.
Alarm value (r2124, floating point):
Actual line frequency determined.
See also: p0285 (Line supply frequency undershot, alarm threshold)
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.
