Set travel units and conversion factors

Select the “Construction” tab.
Select the “Travel” tab and set the transducer conversion factor if needed. Use the “main contact” factor. An additional speed factor can also be set.
Regardless of whether a conversion factor is used, when using a linear transducer, change the default unit from degrees to mm in both the measuring unit and evaluation unit.
Press the back arrow at the top left.

Configure travel connections and sensor type

Select the “Connections” tab and “edit default connections”, or select timing under custom connections if configured.
Select the “Travel” tab.
Open the drop-down under “sensor 1” and select “main contact.”
Select “Brk” when using one transducer, or “3-Ph” when using three transducers, one on each phase.

Select the gear symbol under the sensor 1 drop-down to set the transducer type.
Select a pre-configured sensor from the library or configure a transducer directly here.
For a linear transducer, set “sensor input” to the total length of the motion rod. For a rotary transducer, set it to the total rotational motion, for example 360°.
Select “OK”, then press the back arrow at the top left.

Set closing and opening speed reference points

Select the “Analysis” tab.
Select the “Main contacts” tab.
Select “Close speed” and set the two reference points where closing velocity should be calculated on the travel curve.

The reference points can be set using multiple methods available in the drop-down menu.

Reference-point method drop-down for travel speed analysis

Stroke [absolute] specifies a direct mm or ° position, whereas [relative] specifies a percentage of stroke.
Select “Open speed” to set the reference points for tripping velocity.

Configure damping analysis and save

Damping analysis can also be configured.

Damping analysis configuration screen

Damping can be calculated by “change of velocity”, with the analysis points defined as:

1: Start of damping.
2: Evaluation window start.
3: Evaluation window end.

Alternatively, damping can be calculated from saddle height, with the analysis points defined as:

1: Start of damping.
2: End of damping.
