Bode settings

The settings for the Bode plot, i.e. the frequency responses of the initial recording and the validation measurement, can be adjusted here.

Max frequency: Specifies the upper frequency limit of the Bode plot [in Hz].
Min frequency: Specifies the lower frequency limit of the Bode plot [in Hz].
Frequency Steps: Number of measuring points in the Bode plot.
Position Monitoring Window: Defines a window that is monitored during the Bode plot. The object must not leave this window. The unit actually set is read out and the number is interpreted in accordance with the unit.
Velocity Amplitude Scaling Mode: Scales the signal amplitude during recording so that movements are not too large as the frequency increases. The following are available:

Constant: The amplitude corresponds to the parameterized signal amplitude and remains constant over the entire frequency range.
1 / X at 1000Hz: Scales the amplitude so that at 1000 Hz it has fallen to 1 / X of the start amplitude of 1 Hz (~1/f). Useful ratios in practice are 1/5, 1/10 and 1/20.

Velocity Base Amplitude: Sets the amplitude of the basic oscillation (~1 Hz) for overcoming the static friction. The unit of measurement is to be taken from the system settings (e.g. Drive, NC, etc.) and cannot be specified here.
Velocity Signal Amplitude: Represents the amplitude of the signal (or measurement) oscillation at 1 Hz (see Velocity Amplitude Scaling Mode). The unit of measurement is to be taken from the system settings (e.g. Drive, NC, etc.) and cannot be specified here.
Max current threshold: Target value as a percentage of the measured current when automatic setting of the excitation amplitudes is activated.
Dynamic Container id: Sets the ID of the container for dynamic process data. The DynContainer is appended to the EtherCAT device in the TwinCAT project.
Check Drive Limitations: If you want to check via the axes, you can specify this here.
Maximum Steps per Response: Sets the number of measuring points per system response for broadband excitations (e.g. MultiSine, Chirp, PRBS).
Signal Generator: Displays the excitation type of the signal generator used. The following are available:

Sine: Standard sine oscillation with regard to the set amplitude.
MultiSine: Amplitude-modulated broadband sine.
Chirp: Time-varying, sinusoidal excitation, chirp.
PRBS: The Pseudorandom Binary Sequence (PRBS) approximates a broadband white noise.

Autoscale Gain: Disables/enables the automatic scaling in the gain response chart.
Trace Level: Sets the detail level of the messages generated by the “Drive Diag –TcCom Object” and output in the error list. The available options are Always, Error, Verbose and Warning.
