Measurement
The measurement sequence is divided into the following steps:
1. Setting the traverse range monitoring and the enable logic
2. Selecting the measuring type and measured variable
3. Setting the parameters, softkey "Measuring parameters"
4. Displaying the measurement results, softkey "Display"
Figure 11-2
In the example shown, the speed control loop has not yet been optimized.
A suitable filter parameterization is used to optimize the dynamic response. This can be
called with the "Filter" softkey.
The following figure shows the standard settings for a low-pass filter at 1999 Hz (encoder
mounting frequency).
