Command 'Analyze dynamics'

Function: This command starts a dynamics analysis of the CNC path active in the editor. At the same time, the dimensions for position, velocity, acceleration, and jerk of the CNC path are determined depending on the time, and they are displayed in the time charts of the Dynamics analysis dialog box.

Call: Menu bar: CNC .

Requirement: A CNC path is open in the editor.

Note

In order to perform a dynamics analysis of the CNC path, there must not be any errors in the calculation of their path preprocessing.

Note

The settings in the dialog box are used exclusively for displaying the dynamics analysis and have no effect on the CNC program or CNC settings.

In the dynamics analysis, the time curves for the dimensions of position, velocity, acceleration, and jerk are determined for the entire path that is traveled. The time charts are shown in the dialog box on the same time axis. The settings of the dialog box are used (preset or saved).

Position chart

	Position curve of the selected axis (black)
	Red circle; indicates the beginning of a path element. The tooltip of the marker provides information about the line numbers in the respective G code or in the table.

Velocity chart

Velocity curve of the selected axis (blue)

Acceleration chart

Acceleration curve of the selected axis (green)

Jerk chart

Jerk curve of the selected axis (orange)

The settings are saved when closed and used the next time the dialog is opened. For example, the zoom factor make only part of the curve visible.
	Zooms into one part of the time curves Alternative: Ctrl++ Ctrl+Mouse Wheel
	Zooms out of time curves Alternative: Ctrl+- Ctrl+Mouse Wheel
	Zoom into the time curves so that the entire CNC paths are displayed.
Axis	Selection of axes: X , Y, Z, A, B, C, A1(P), A2(Q), A3 (U), A4(V), A5(W), A6, or Path Preset: X axis Path axis: Display of path position, path velocity, path acceleration, and path jerk.
Cycle time [µs]	Value for the dwIpoTime input of the SMC_Interpolator function block Preset: Value Cycle time [µs] in object CNC settings (tab Preinterpolation)
Velocity mode	Value for the iVelMode input of the SMC_Interpolator function block
Trapezoid	Trapezoidal velocity profile
Sigmoid	Like Trapezoid, but rising or falling edges are replaced by sin² functions of the same surface. In this velocity mode, the limiting value is exceeded by approximately a factor of π/2.
Sigmoid limited	Like Sigmoidal, but the duration for interpolating the path is the same length as in the velocity mode Trapezoid. Preset
Quadratic	Acceleration profile in trapezoidal form with jerk limitation. The jerk reaches a maximum value in Maximum jerk [u/s³]. This leads to a quadratic velocity profile. The position profile consists of third-degree polynomials. The result is that the velocity profile consists of parabolas, the acceleration consists of linear segments, and the jerk consists of horizontal line segments.
