Table Editors 3.6

Using RMCWin 3-49

When the Target Speed is calculated, smoothing is performed so it does not vary by such a large

amount, but some jaggedness is left from rounded-off position units.

3.5.10.2 Raw Transducer Counts

The Raw Counts (lo) field holds bits 0-15 of the Transducer Counts at the given plot time period.

The Raw Counts (hi) field is provided for use by technical support, but also holds bits 16 and 17

of the current count. Therefore, if you are using counts above 65,535, you can combine the two

fields to find the actual counts at each point on the graph.

3.5.10.3 Sum of Errors Squared

This field is computed by summing the squares of the position error for each time unit on a graph.

The lower this value, the closer the actual position curve tracked the target position curve. The

numerical value displayed in this field has no meaning by itself, but it can be used during tuning to

check whether a tuned parameter was helpful or harmful to the tracking of the position. In order to

have a valid comparison the two graphs must have the same length, and the moves need to have

had the same target profile. Otherwise, the changed parameter is not isolated in the test.

3.5.10.4 Sum of Analog Errors Squared

This field is computed by summing the squares of the analog error for each time unit on a graph.

The lower this value, the closer the actual analog curve tracked the target analog curve. The

numerical value displayed in this field has no meaning by itself, but it can be used during tuning to

check whether a tuned parameter was helpful or harmful to the tracking of the target curve. In

order to make a valid comparison, the two graphs must be the same length, and the target analog

profiles must be roughly the same. Otherwise, the changed parameter is not isolated in the test.

3.6 Table Editors

3.6.1 Table Editor Basics

Starting a Table Editor

To start an editor, from the Tools menu, click the desired editor. Notice that each editor also has

a shortcut key that can be used to start it. These are displayed in the menu.

When the table editor is opened, the following steps will be taken:

1. For the tables other than the Stored Command table: if an RMC is connected to the RMCWin, the

table will be read from the module.

2. If an RMC is not connected to RMCWin, the table will be read from a file. The filename used is

given by the board filename, with the appropriate extension appended.

3. If an RMC is not connected to RMCWin and the table could not be read from disk, then default

values will be filled into the table.
