Rockwell Automation 1557 MEDIUM VOLTAGE AC DRIVE - Manual (Page 125)

OPERATOR INTERFACE TERMINAL PV-550 REV E 7-1
1557-UM050F-EN-P – June 2013
Chapter Objectives
This chapter describes how you use the terminal to modify and obtain information contained within the
drive. In this chapter you will learn how to:

Modify information associated with the initial drive setup.

View: - drive variables,
- drive parameters,
- drive status.

View & Reset Alarm Conditions.

Request printouts of the information in the drive.

Perform diagnostic trending.

Modify the operation of the terminal.
The chapter deals only with the operation of the terminal. Specific references to a particular parameter or
variable is only for illustrative purposes. Refer to Chapter 6 "Parameters and Variable Descriptions" for
information about the actual 'tags' within the drive and their use.
Terminology
Parameter – a memory location within the drive to which data may be written to or read. Setting a
parameter (ie. writing to it) will modify how the drive behaves. Prior to using the drive a number of
parameters must be set. Additional parameters may be changed while the drive is in use in order to
adjust its operation, (ie. the speed could be changed via a parameter).
Variable – a memory location which can only be read. A variable contains real-time data and is used to
read the current conditions within the drive, such as running speed.
Tag – A generic reference to either a parameter or a variable.
PanelView 550 – The PanelView 550 is a product marketed by Rockwell Automation consisting of a
hardware terminal and a software package, integrated into a single product. The Medium Voltage Drive
only uses the hardware portion of the product and has replaced the software package.
Terminal – References to the terminal refer to the product consisting of the PanelView 550 hardware and
the unique software contained within it, which allows it to function with the Medium Voltage Drive.
Monitor – An ASCII terminal used by service technicians to connect directly to the Drive Control Boards
via an RS232 link.
Editing Field – An area of a screen which is displayed in reverse video. When the field is in this state,
data may be entered into it via the keypad.
Operation – A task which is to be performed. In order to complete the task, a number of screens may be
involved. Ie. selecting a parameter is an operation which requires at minimum two screens. This
operation itself is an operation of modifying a parameter.
