Cu: Pulse Frequency Inconsistent - Siemens SINAMICS DCM List Manual

4 Faults and alarms
4.2 List of faults and alarms
7: Value not a multiple of 375 µs.
8: Value not a multiple of 400 µs.
10: Special restriction of the drive object violated.
20: On a SERVO with a sampling time of 62.5 µs, more than two drive objects or one drive object of a type other than
SERVO have been detected on the same DRIVE-CLiQ line (a maximum of two SERVO type drive objects are
permitted).
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 (31.25 µs is not supported for SMC10, SMC30, SMI10 and Double Motor Modules).
32: Value less than 125 µs.
33: Value less than 250 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 time 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
sampling 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).
45: A chassis parallel 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 162.5 µs or 187.5 µs (for a 2
or 3x parallel connection).
46: A node has been identified on the DRIVE-CLiQ line whose sampling time is not a multiple of the lowest sampling
time on this line.
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
documentation).
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.

CU: Pulse frequency inconsistent

Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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 lower than minimum value.
2: Value higher than maximum value.
