Display Variables & Parameters
The variables and the parameters of the drive can be displayed, continually showing the value
contained in the drive. From the Top Level Menu, press the [F4] key. The DISPLAY GROUP
screen of Figure 56 is displayed.
The screen shows one or more pages of groups which can be displayed. Using the [cursor up]
and [cursor down] keys select the group you wish to display and press the [enter] key.
The DISPLAY screen, typical of Figure 57, is displayed. The screen shows the name of the group
being displayed to the right of the screen name (ie. P Nameplate). One or more pages of the
members in the group are displayed along with the value for this tag in the drive and its unit of
measurement. These values are updated from the drive on a continual basis.
From the DISPLAY screen, it is possible to modify a parameter. If the group you are currently
viewing contains parameters, press the [F7] key. The terminal then allows you to select the
parameter you wish to modify. Refer to the section entitled "
Modify Parameters" for further details.
If you have modified any parameters in the drive, you will be prompted to make the changes
permanent. This prompt will occur upon exiting the DISPLAY GROUP screen. Refer to "
Message Prompting" for further details.
Custom Group
From the DISPLAY GROUP screen (Figure 56) you can select a group which you have custom
defined by pressing the [F7] key. This custom group contains selected tags from one or more
other groups, arranged by you onto a single screen for more convenient viewing, (Figure 58).
To assign a tag to the display, use the [cursor up] and [cursor down] keys to highlight the desired
item position and press the [enter] key. This will begin the selection process of a tag as described
in the section entitled "Select a Parameter/Variable". When you have completed the selection
process, the selected tag will be assigned to the item, as in Figure 59. To remove a tag from the
highlighted item, press the [delete] (Backspace) key.
