Overview of Alarms
SINAMICS-Alarms
206321 <location>Master/slave: 6-channel multiplexer control not valid
Message %1
value:
Drive object: A_INF
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Values 0, 1, 2, 3, 4 and 5 are valid to control the 6-channel multiplexer via CI: 3577. In this case, an
invalid value was identified. The control remains effective with the previous value.
Fault value (r0949, interpret decimal):
Invalid value to control the multiplexer.
See also: p3577 (Master/slave current distribution factor, multiplexer selection)
Remedy: - check the interconnection to control the multiplexer (CI: p3577).
- check the signal source signal value of the BICO interconnection.

206350 <location>Infeed: Measured line frequency too high
Message Line frequency: %1
value:
Drive object: A_INF, S_INF
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 oper-
ational fault.
Alarm value (r2124, floating point):
Current 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.
See also: p0211 (Rated line freq), p0284 (Line supply frequency exceeded, alarm threshold)
206351 <location>Infeed: Measured line frequency too low
Message Line frequency: %1
value:
Drive object: A_INF, S_INF
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):
Current line frequency determined.
See also: p0285 (Line supply frequency undershot, alarm threshold)
