Rockwell Automation 1557 MEDIUM VOLTAGE AC DRIVE - Manual (Page 131)

OPERATOR INTERFACE TERMINAL PV-550 REV E 7-7
1557-UM050F-EN-P – June 2013
Language Changing
When the language used by the drive changes, (either via the terminal or an external device), the
terminal must do considerable work. The database strings are all invalidated, the character set
for the server is changed and all strings used by the terminal are linked to the new language.
During this possibly lengthy process, the “Language Changing ...” message is displayed.
General Operation
The operations which can be performed on a screen varies depending on the actual screen being
displayed. The majority of the operations are activated by the function keys located along the
bottom of the screen. Although the meaning of these keys do change from one screen to the
next, there are some functions which are available on most screens and always have the same
assignment.
The operations for these latter keys will not be explained within the description of individual screen
operations. They are explained here and apply equally to all screens.
F1 - Help
This operation is active on every screen, even if the 'Softkey' is not displayed. Help is context
sensitive and will display help which relates to the screen which you are currently viewing.
