Selecting the Data to Plot

All plots read from the motion controller contain the following information:

• ACTUAL POSITION

• TARGET POSITION

• DRIVE

• STATUS word

In addition, ACTUAL SPEED and TARGET SPEED are calculated from the ACTUAL

POSITION and TARGET POSITION values and stored in the plot.

The motion controller can provide two more pieces of data; the user chooses what data is

collected using the Plot Options dialog box. To use this dialog box:

1. If you are going to change the extra graph information on only one axis, select a

field in the axis.

2. On the Tools menu, click Plot options.

3. Click the option button of the data you want to include. The options are described

below.

4. If you wish to change the extra graph information for all axes, select the Set for all

axes check box.

5. Click OK.

6. Trigger a new graph to be stored by the module. This requires making a new move

because the new information is not collected until the module begins a new graph.

The four extra pieces of information that can be included are:

• Extra Position Precision – No additional data is displayed in the graph when this

data is selected. Instead more precise positions are read from the module, which

results in the better speed calculations. Use this option to get better approximations of

the speed.

• Command/Command Value – The last command and command value received on

the axis are stored for every plot entry. This is useful to verify the arrival and effects

of new commands given during a move. NOTE: commands given from the monitor

program are not included in the plot data.

• Current Event/Link Value – The current event STEP and LINK VALUE are stored

for every plot entry. This is useful for debugging event sequences.

• Raw Transducer Counts – The raw counts read from the transducer are stored for

every plot entry. Refer to Raw Transducer Counts for details.

Using the Plot Detail Window

A plot detail window is opened by default when a plot is read into the monitor program.

This window has a title of Data at 0.000 s with the actual number changing depending on

thehairlineposition. Thehairlineisaverticallinethatcanbemovedusingthearrow

displayed in the detail window represent the plot at the hairline position. Therefore, to
