– p0115[3]: Sampling times for internal control loops, setpoint channel
– p0115[4]: Sampling times for internal control loops, position controller
– p0115[5]: Sampling times for internal control loops, positioning
– p0115[6]: Sampling times for internal control loops, technology controller
The display of the parameter values set for p0115 changes depending on the default
setting made.
Note
If the sampling times of the current controller and speed controller are changed (see also
p0115), it is recommended that the controller settings are recalculated via p0340
=
4 after
the commissio
ning (p0010 = 0).
Entering the sampling times manually
If you have set "Expert" in p0112, you can manually configure each of the following sampling
times for the following control loops (p0115):
● p0115[0]: Sampling times for internal control loops, current controller
● p0115[1]: Sampling times for internal control loops, speed controller
● p0115[2]: Sampling times for internal control loops, flux controller
● p0115[3]: Sampling times for internal control loops, setpoint channel
● p0115[4]: Sampling times for internal control loops, position controller
● p0115[5]: Sampling times for internal control loops, positioning
● p0115[6]: Sampling times for internal control loops, technology controller
Note
You cannot set the values arbitrarily. The rules for setting the sampling times can be found in
Chapter "System rules, sampling times and DRIVE
-CLiQ wiring" of the SINAMICS S120
Function Manual Drive Functions.
Enter the sampling times for the internal control loops.
Setting the pulse frequency
Set the pulse frequency via p1800.

Actual value processing
The actual value processing is used to determine the cyclic and absolute actual values of the
encoder, and to transfer the encoder position from the drive to an open-loop control/position
control.
