TestWare-SX Monotonic Command

A monotonic command process produces a command signal that controls a servovalve or servomotor. This process should be sequenced in series with other command processes.

How it works

A monotonic command starts at the current level and ends at another level. You assign one of three wave shapes, a time, and a control mode to a monotonic command. The starting level is the end level of the previous command process. Both relative and absolute end levels are supported.

More Information

The Monotonic Command Design window names the process and sequences it in a test template.

The Monotonic Command Parameters window defines the control mode and hold time.


Monotonic Command Design Window

This window specifies when the process starts and stops. The information in this window is saved with the test template.

Using the window

Use this window to designate a single test command process in a step.

1	Name the process with the Label entry field.

2	Select a Start Trigger to sequence the process. This process should be sequenced in series with another command process.

3	Select an End Trigger to stop the process. Use the default nonetrigger if you want the process to complete without interruption.

4	Select a Control Channel for the process.

More Information

You can find detailed information about this process in Chapter 6 of the 790.10 TestWare-SX Application Manual.

After you complete this window, you can double-click the name of this process in the Edit Template window to display the Monotonic Command Parameters window. This allows you to assign parameters to the default procedure.


Monotonic Command Parameters Window

You must create a monotonic command process in a template with the Monotonic Command Design window before you can access this window. The information in this window is saved with the test procedure.

Segment Shape

Specifies a single test command that starts at one level and ends at a different level. Lists the segment shapes you can select and whether the end levels are relative or absolute.

Haversine

Ramp

Step

Rate Type

Lists the types of expressions you can select to define a cycle. The rate type allows you to specify the units you prefer to define a segment. The types of expressions are:

Frequency

Time

Rate

Frequency, Time, or Rate

Specifies the monotonic command value. The label and type of units depend on the selected Rate Type above.

Control Channels

Displays a list of the control channels selected in the Design window.

Control Mode

Selects the control mode for the monotonic command. Pressing the list icon lists the control modes defined with the Controller Definition program.

End level

Specifies the end level of the segment. The starting level is the level of the previous test command.

Using the window

1	Select a control channel.

2	Complete the control channel portion of the window to define cycle parameters that are unique for each control channel.

Select a control mode, an end level, and end level units.

3	The upper portion of the window defines the segment parameters that are common for each of the listed control channels.

Select a segment shape, rate type, and rate type units.

4	Enter the rate type value.
