Cu: Pulse Frequency Inconsistent - Siemens Sinamics S120 Diagnostic Manual

21: Value can be a multiple of the current controller sampling time of a servo or vector drive in the system (e.g. for
TB30, the values of all of the indices should be taken into account).
30: Value less than 31.25 µs.
31: Value less than 62.5 µs.
32: Value less than 125 µs.
40: Nodes have been identified on the DRIVE-CLiQ line whose highest common denominator of the sampling times
is less than 125 µs. Further, none of the nodes has a sampling tine of less than 125 µs.
41: A chassis unit was identified on the DRIVE-CLiQ line as a node. Further, the highest common denominator of the
sampling times of all of the nodes connected to the line is less than 250 µs.
42: An Active Line Module was identified on the DRIVE-CLiQ line as a node. Further, the highest common denominator
of the sampling times of all of the nodes connected to the line is less than 125 µs.
43: A Voltage Sensing Module (VSM) was identified on the DRIVE-CLiQ line as a node. Further, the highest common
denominator of the sampling times of all of the nodes connected to the line is not equal to the current controller sam-
pling time of the drive object of the VSM.
44: The highest common denominator of the sampling times of all of the components connected to the DRIVE-CLiQ
line is not the same for all components of this drive object (e.g. there are components on different DRIVE-CLiQ lines
on which different highest common denominators are generated).
52: Nodes have been identified on the DRIVE-CLiQ line whose highest common denominator of the sampling times
is less than 31.25 µs.
54: Nodes have been identified on the DRIVE-CLiQ line whose highest common denominator of the sampling times
is less than 62.5 µs.
56: Nodes have been identified on the DRIVE-CLiQ line whose highest common denominator of the sampling times
is less than 125 µs.
58: Nodes have been identified on the DRIVE-CLiQ line whose highest common denominator of the sampling times
is less than 250 µs.
99: Inconsistency of cross drive objects detected.
116: Recommended clock cycle in r0116[0...1].
General note:
The topology rules should be noted when connecting up DRIVE-CLiQ (refer to the appropriate product documenta-
tion).
The parameters of the sampling times can also be changed with automatic calculations.
Example for highest common denominator: 125 µs, 125 µs, 62.5 µs --> 62.5 µs
Remedy: - check the DRIVE-CLiQ cables.
- set a valid sampling time.

201224 <location>CU: Pulse frequency inconsistent
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When changing the minimum pulse frequency (p0113) inconsistency between the pulse frequencies was identified.
Alarm value (r2124, interpret decimal):
1: Value, low minimum value.
2: Value, high maximum value.
3: Resulting sampling time is not a multiple of 1.25 µs.
4: Value does not match clock-cycle synchronous PROFIBUS operation.
10: Special restriction of the drive object violated.
99: Inconsistency of cross drive objects detected.
116: Recommended clock cycle in r0116[0...1].
Remedy: Set a valid pulse frequency.
