201223 <location>CU: Sampling time inconsistent
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When changing a sampling time (p0115[0], p0799 or p4099), inconsistency between the clock cycles
has been identified.
Alarm value (r2124, interpret decimal):
1: Value, low minimum value.
2: Value, high maximum value.
3: Value not a multiple of 1.25 µs.
4: Value does not match clock-cycle synchronous PROFIBUS operation.
5: Value not a multiple of 125 µs.
6: Value not a multiple of 250 µs.
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: For a SERVO with a 62.5 µs sampling time, more than a maximum of two SERVO-type drive
objects were detected on the DRIVE-CLiQ line (no other drive object is permitted on this line).
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 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 com-
mon 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).
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].
Note:
The topology rules should be noted when connecting up DRIVE-CLiQ.
The rules are, provided in the following document:
SINAMICS S120 Function Manual Drive Functions
The parameters of the sampling times can also be changed with automatic calculations.
Remedy: - check the DRIVE-CLiQ cables.
- set a valid sampling time.
