Arrow Keys
There are four yellow arrow keys on the Perfect Harmony keypad. The up and down arrow keys ([ ] and [ ]) are
located in the upper right corner of the keypad. The left and right arrow keys ([ ] and [ ]) are located on the lower
row of the keypad. Common uses of the arrow keys include:
•
Navigating through the menu structure
•
Scrolling through lists of parameters
3
•
Incrementing/decrementing parameter values (when in edit mode)
•
Manually advancing to the next digit (when in edit mode)
•
Increasing (up arrow [ ]) and decreasing (down arrow [ ]) the desired velocity demand of the drive (when
in local manual mode)
•
Clearing security level (press [SHIFT] + [ ] 3 times from the default meter display)
•
Entering menu access mode ([SHIFT] + [ ])
The left and right arrow keys ([ ] and [ ]) can be used to navigate through the menu structure of the Perfect
Harmony system. In general, the right arrow [ ] is used to penetrate deeper into the menu structure and the left arrow
[ ] is used to back out of the menu structure. For example, from the main display, the operator can press the right
arrow key [ ] to access the Main menu.
The up and down arrow keys ([ ] and [ ]) can be used to scroll through lists of items. For example, after using the
right arrow key [ ] to reach the Main menu, the operator may select the down arrow key [ ] to scroll through the list
of options within the Main menu. These options may be parameters, pick lists, or submenus. Refer to the next section
for information about the structure of the menu system.
The up and down arrows ([ ] and [ ]) can be used to increment or decrement the desired velocity demand when the
system is in local manual mode (refer to 3.2.4). As the up and down arrow keys are pressed, the changes in desired
velocity demand can be viewed from the main display on the LCD. Refer to Figure 3-6.
Note: The velocity demand field (DEMD) on the front panel display is assigned by default. This display
assignment (and the other three) can be changed from the menu system.
