Revised 7/95 DFS-1 Manual
POWERTEC Ind. Corp.©
4.0 DFS - 1 SETUP
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.
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.
