201205 <location>CU: Time slice overflow
Message %1
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: Insufficient processing time is available for the existing topology.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - reduce the number of drives.
- increase the sampling times.
201210 <location>CU: Basic clock cycle selection and DRIVE-CLiQ clock cycle
do not match
Message Parameter: %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The parameter to select the basic clock cycle does not match the drive topology. Drives connected to
the same DRIVE-CLiQ port of the Control Unit have been assigned different basic clock cycles.
Fault value (r0949, interpret decimal):
The fault value specifies the parameter involved.
See also: r0111 (Basic sampling time selection)
Remedy: Only those drive objects may be connected to the same DRIVE-CLiQ socket of the Control Unit that
should run with the same basic clock cycle.
For example, Active Line Modules and Motor Modules should be inserted at different DRIVE-CLiQ
sockets as their basic clock cycles and current controller clock cycles are generally not identical..

201220 <location>CU: Bas clk cyc too low
Message Parameter: %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The parameter for the basic clock cycle is set too short for the number of connected drives.
Fault value (r0949, interpret decimal):
The fault value specifies the parameter involved.
See also: r0110 (Basic sampling times)
Remedy: - increase the basic clock cycle.
- reduce the number of connected drives and start to re-commission the unit.

201221 <location>CU: Bas clk cyc too low
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The closed-loop control / monitoring cannot maintain the envisaged clock cycle.
The runtime of the closed-loop control/monitoring is too long for the particular clock cycle or the com-
puting time remaining in the system is not sufficient for the closed-loop control/monitoring.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Increase the basic clock cycle of DRIVE-CLiQ communication.
