4 Faults and alarms
4.2 List of faults and alarms
Remedy: - check the sampling time setting (p0112, p0115, p4099, p9500, p9511).
- contact the Hotline.
F01205 CU: Time slice overflow
Drive object: All objects
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.
F01221 CU: Bas clk cyc too low
Drive object: All objects
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.
See also: p0112 (Sampling times pre-setting p0115)
F01222 CU: Basic clock cycle too low (computing time for communication not available)
Drive object: DCP_CTRL, TM150
Cause: A time slice has not been defined that fulfills the requirements.
The port cannot be correctly operated as the alternating cyclic clock cycle cannot be maintained.
Fault value (r0949, interpret hexadecimal):
Method ID.
Note:
Only for internal Siemens troubleshooting.
Remedy: Contact the Hotline.
A01223 CU: Sampling time inconsistent
Drive object: All objects
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 lower than minimum value.
2: Value higher than 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
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.
