6.5.8 Current controller cycle clocks <> 125 µs / use of output cams and measuring
inputs
If current controller cycle clocks <> 125 µs are used, the parameter calculations of the drive
must be transferred to the PG when using cam outputs on the TM15 / TM17 High Feature or
for global measuring inputs, and FastIO configuration generated again.
A change of the current controller cycle clock may have effects on the sampling times of the
inputs/outputs on the drive side (e.g. TM15/TM17 High Feature, p4099 Sampling time of the
inputs/outputs).
Sampling times <> 125 µs occur in the following cases:
● For servo drives with manual change of the current controller sampling time (drive
● For vector drives depending on the number of vector drives and with chassis units
● If only an infeed and no drives are connected to the drive unit, then the sampling time is
For the cam outputs and the measuring input inputs (only for global measuring inputs) to
function correctly, the sampling times must be known to the engineering system.

In order that the changed cycle clock ratios are taken into account by the the engineering
system, proceed as follows:
1. Go online and perform a project download. The SINAMICS performs parameter
2. Perform an upload to the PG ("Target system" > Load" > "Load CPU / drive unit to PG").
3. This transfers the parameter calculations of the drive to the PG. The cycle clock ratios are
