MENU AND KEYPAD HIERARCHY

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 . . .
