11.2 Frequency response measurements
Measurement
The measurement sequence is divided into the following steps:
1. Setting the traverse range monitoring and the enable logic.
2. Selecting the measurement type
3. Setting the parameters, softkey "Measuring parameters"
4. Displaying the measurement results, softkey "Display"

Current controller
Magnitude of the test signal amplitude. Given in percent of the peak torque. Values from
1% to 5% are suitable.
The frequency range analyzed with the measurement.
The bandwidth depends on the current controller sampling time.
Example:
125 μs current controller sampling time, set bandwidth 4000 Hz
