F01210 CU: Basic clock cycle selection and DRIVE-CLiQ clock cycles do not match
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 (Basis 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 different.

F01220 CU: Bas clk cyc too low
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 (Basis sampling times)
Remedy: - increase the basic clock cycle.
- reduce the number of connected drives and start to re-commission the unit.

F01221 CU: Bas clk cyc too low
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The closed-loop control / monitoring cannot maintain the intended clock cycle.
The runtime of the closed-loop control/monitoring is too long for the particular clock cycle or the computation 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 communications.

A01223 CU: Sampling time inconsistent
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 minimal 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).
