Remedy: Check the DRIVE-CLiQ connection:
Approximately the same number of components should be connected in series and
operated at the DRIVE-CLiQ connections. This means that communication is uniformly
distributed over several communication lines.
Re fault value = 1yy - 4yy in addition:
- increase the basic clock cycle (p0112).
201355 <location>Topology: Actual topology changed
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The unit target topology p0099 does not correspond to the unit actual topology r0098.
The fault only occurs if the topology was commissioned using the automatic internal device
mechanism and not using the commissioning software.
Fault value (r0949, decimal):
Only for internal Siemens troubleshooting.
See also: r0098, p0099
Remedy: One of the following counter-measures can be selected if no faults have occurred in the
topology detection itself:
If commissioning was still not completed:
- carry-out a self-commissioning routine (starting from p0009 = 1).
general: Set p0099 to r0098, set p0009 to 0; for existing motor modules, this results in
servo drives being automatically generated (refer to p0107).
or to generate servo drives: Set p0097 to 1, set p0009 to 0;
or to generate vector drives: Set p0097 to 2, set p0009 to 0.
or to generate vector drives with a parallel circuit configuration: Set p0097 to 12, set p0009
to 0.
In order to set configurations in p0108, before setting p0009 to 0, it is possible to first set
p0009 to 2 and p0108 modified (the index corresponds to the drive object,also refer to
p0107).
If commissioning was already completed:
- re-establish the original connections and re-connect power to the control unit.
- restore the factory setting for the complete equipment (all of the drives) and allow
automatic self-commissioning again.
- change the device parameterization to match the connections (this is only possible using
the commissioning software).
Notice:
Topology changes, that result in this fault being generated, cannot be accepted by the
automatic function in the device, but must be transferred using the commissioning software
and parameter download. The automatic function in the device only allows constant
topology to be used. Otherwise, when the topology is changed, all of the previous
parameter settings are lost and replaced by the factory setting.

201360 <location>Topology: Actual topology is illegal
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The detected actual topology is not permissible.
Fault value (r0949, hexadecimal):
Byte 1 (cause):
1: Too many components were detected at the control unit. The maximum permissible
number of components is 199.
2: The component type of a component is not known. The preliminary component number
is in the high word.
Note:
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
