Rockwell Automation 1557 MEDIUM VOLTAGE AC DRIVE - Manual (Page 127)

OPERATOR INTERFACE TERMINAL PV-550 REV E 7-3
1557-UM050F-EN-P – June 2013
Overview
The terminal used on the Bulletin 1557 Medium Voltage Drive is that of the PanelView 550 (Figure 1).
This terminal however does not behave as a PanelView, as only the hardware for the terminal has been
utilized. The PanelView software has been replaced with unique software to tailor it to the requirements of
the Medium Voltage Drive.
Keypad
The keypad of the terminal consists of two rows of five functions keys (item 1 of Figure 1) located
below the terminal's display area (item 4 of Figure 1). In the lower right corner of the terminal are
four keys which will be referred to as the cursor keys (item 2 of Figure 1). Above the cursor keys
are data entry keys consisting of the numeric values 0-9, a decimal point (.), a negative (-), a
backspace key and a data entry key (item 3 of Figure 1).
All keys are of a membrane type. The key is executed upon release.
Function (Softkeys) Keys
Along the bottom of the display area is one or two rows of 'Softkeys'. These 'Softkeys' represent
the physical function keys. The function of the actual keys will vary between displays. The bottom
row of keys (ie. F6-F10) is always shown. The upper row is shown only if they are required for
keys (F2-F5). Thus a single row of 'Softkeys' always refers to the keys F6-F10.
Even though the upper row of Softkeys (ie. F1-F5) may not be shown on some displays, the
F1-HELP key is always active. (F2-F5) are only active if shown.
