2. After the calculation type has been set (exception: "No calculation"), you can confirm the
calculation if this has not been done already (red status symbol).
To do this, click the "Confirm calculation" button.
The "Technology application" option is then disabled for the drive functions and the set
application can no longer be changed. The disable can be cancelled via the "Enable"
button. If you have canceled the disable, then you must subsequently reconfirm the
calculation type.

Sampling times/pulse frequency

☐
From a pulse frequency of 800 Hz and higher, we recommend that you enter the sampling
times and the pulse frequency for the drive. The setting is made using the following screen
form:
Note
You can only activate or deactivate the "Sampling times/pulse frequency" function when you
are OFFLINE.
Setting the defaults
The sampling times are preset via parameter p0112.
1. Select one of the following defaults via the drop-down list (p0112):
– [0] Expert
– [1] xLow
– [2] Low
– [3] Standard
– [4] High
– [5] xHigh
The designation of the defaults refer to the desired output frequency and control dynamic
response. If a particularly high output frequency or control dynamic response is required,
"xHigh" would be the correct default. The selected default affects the following control
loops:
– 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

The equivalent circuit diagram data entered during the parameter assignment of the
motor is not changed. The equivalent circuit diagram data is not calculated.
