Cu: Time Slice Overflow; Cu: Bas Clk Cyc Too Low; Cu: Sampling Time Inconsistent - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
201205 <location>CU: Time slice overflow
Message value: %1
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.
201221 <location>CU: Bas clk cyc too low
Message value: %1
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 computing 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.

201223 <location>CU: Sampling time inconsistent
Message value: %1
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 iden-
tified.
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: 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 permit-
ted).
