Cause : CU: Sampling time inconsistent - 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, 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.

Remedy:

- check the DRIVE-CLiQ cables.
- set a valid sampling time.
