Step 10: Scale and Offset

deltamotion.com

Step 10: Scale and Offset

The Scale and Offset parameters convert the Counts, Volts or Current
from the transducer into meaningful measurement units.

First, determine the approximate positions at either end of travel. This
will help you verify later that you performed the procedure correctly.

To set the Scale and Offset:

Go to the

Axes Parameters

pane,

Setup

tab,

Tools and Wizards

section.

Click

Launch

for the Scale/Offset

Wizard in the desired axis.

In the wizard, follow the directions. For help, press the

Help

button.

Tip:

If the wizard does not work for your system, you can manually
determine the Scale and Offset parameters. See the Scaling topic
in the RMCTools help for details.

After completing the wizard, in
the

Axis Parameters

, locate the

Display Units

parameter.

Select the desired display units.
If you wish to use units that are
not listed, choose

Custom

, then

type up to 4 characters in the

Custom Units

parameter.

Click the

Download

button to apply the changes to the RMC.

Remember to save your project and update Flash.
