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.
Sampling times <> 125 µs occur in the following cases:
●
For servo drives with manual change of the current controller sampling time (drive
parameters p0112 and p0115[0])
● For vector drives.

In order that the changed cycle clock ratios are taken into account by the engineering system,
proceed as follows:
1. Go
online and perform a project download. The SINAMICS performs parameter calculations
once.
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
then known in the engineering system.
4. Go offline.
5. Generate the configuration information (Fast IO configuration) again. To do this, select the
SIMOTION CPU in the project tree and right-click to open the context menu "Fast IO" >
"Create new configuration".
6. Execute "Project" > "Save and compile all."
7. Go online and download the project to the target system.
8. Save the data on the CF card.
SIMOTION SCOUT uses the described procedure to calculate internal system data that is
required for outputting/detecting signals with a high level of position accuracy.
Note
If
the cycle clock ratios are not set correctly, an appropriate message is output in the diagnostic
buffer.
