Revised 7/95 DFS-1 Manual
POWERTEC Ind. Corp.©
APPENDIX B
MENU AND KEYPAD HIERARCHY
When the DFS-1 is shipped, the factory presets
the unit’s parameters according to the motor and
drive’s specifications. The following pages describe
the keypad’s hierarchal menus when the KDU-1
keypad and display unit has been installed and
configured.
At the opening menu level, the DFS-1’s status is
displayed. The STATUS display shows the com-
manded speed, the load as a percent of Full Load
Amps, and the actual motor speed. If speed setpoint
changes are allowed, the up and down arrows can be
used to trim the drive.
Of the seven keys on the keypad, the CMD key is
the only one which always has the same function. If
the drive is in LOCAL and there is no analog input
associated with speed reference, the CMD key will re-
turn to the status display in the edit mode. This edit
mode can be recognized by the presence of a cursor
under one digit position of the commanded speed be-
ing displayed. In this mode, the right and left arrow
keys move the cursor left and right changing the digit
position being edited. The up and down arrows will
modify the value of the digit being edited by increment-
ing or decrementing the value by one unit.
The SEL key will always return to the next
higher level without saving changes.
The ENT key will save changes and return to the
status display except in the Setup/Parameters mode
where it will save changes and return to the previous
parameter menu.
NEMA standards define forward as counter-
clockwise rotation of the shaft as viewed facing the
front of the motor. On a brush DC motor, the front
end is the commutator end while on a brushless DC
motor the front end is the encoder end (normally
opposite from the output shaft).
While in the status display mode, pressing the
FWD key will cause the motor to run in the forward
(clockwise) mode.
Likewise, pressing the REV key will cause the
motor to run in the reverse (counterclockwise) mode.
Pressing the STP key will command the motor to
stop. The manner in which the motor stops is
determined by Setup Parameters.
In order to begin changing drive setup param-
eters, one must first press the MENU button. This
action will return the options represented by Fig. 1 on
the following page.
The charts on the following pages, show the
hierachal order of the options available. In most
every case, up and down arrow keys scroll through
selection for a particular menu level while the
ENTER key will either move to the next hierarchal
level or set a point and save the change. The
SELECT key will return to the top of the hierarchal
level without saving any change. For example,
pressing the Menu button will result in a two line
display of SETUP/PARAMETERS. Pressing the
down triangle (arrow) will cause the next menu item,
SETUP/ENB/DSB BKLT to appear. At this point
pressing ENT will result in choices of up arrow to
Enable and Down arrow to disable the LCD back-
light. On the other hand, choosing the SEL will go
back to the SETUP/ENB/DSB BKLT menu. In
cases where a selection will go to another hierarchal
level, this chart will show a Fig. number which refers
to the next chart. For example, in Figure 1, Param-
eters, pressing the ENTER key will take one to . . .
