The DFS-1 is shipped with a default set of parameters which allows it to be connected as shown in Figure 3 on page 3 and run with basic push- buttons and a speed pot. This supplies a "baseline" of operation which may be used to test the functionality of the board.

The above parameters are the most commonly used ones. For other default settings, refer to the parameter descriptions beginning on page 15.

If your needs are met by the list above, then all you have to do is hook up the drive to power and to the motor and run it. No changes in parameter settings are necessary.

Making parameter changes requires the optional keypad display unit or a computer with serial communications capability.

This section covers the basic steps necessary to set up the DFS-1 beyond the needs of the default parameters. The setup is arranged roughly from the most basic and common steps to the least commonly used parameter changes. You need only follow the steps until you have all the parameters you will use checked and/or changed.

For the purposes of this chapter, it will be assumed that the setup is being accomplished through the use of the KDU-1 keypad display unit.
