Appendix C SETUP PARAMETERS
The shipping configuration in the 590 DRV Digital drive allows the user to start up and run a DC motor in simple
speed control. The power of the 590SP, however, is its configurability and its ability to be tuned for optimum perfor-
mance or for a specific control application. The parameters which are most frequently adjusted for tuning and
performance are in the SETUP PARAMETERS MMI menu. They are categorized by sub-menus. Each sub-menu
acts as a function block within the drive's overall software block diagram which processes logic signals and speed or
current input signals.
This chapter describes the functionality of only the drive parameters located within SETUP PARAMETERS. Refer to
Appendix M for descriptions and application information of the parameters within the SPECIAL BLOCKS menu.
You can adjust the drive's parameter settings either through the MMI under the SETUP PARAMETERS sub-menu or
by using a personal computer (PC) running the software package ConfigEd Lite (see the ConfigEd Lite Software
Manual RG352747). You can also configure the drive— or connect and reconnect signals between drive function
blocks and I/O terminals— either through the MMI or with a PC. For software configuration through the MMI, refer
to Appendix D.
This chapter is arranged in the order the sub-menus, or function blocks, appear in the MMI. Each section contains a
description of the function block's parameters, a schematic block diagram and a table listing all the block's parameters,
a description of each parameter and the parameter's signal range and "as shipped" default value. The configuration tag
number correpsonding to each drive parameter also appears in the table. In addition, each section includes a drawing
illustrating how to access the parameter function block through the MMI. Additional information, such as timing
diagrams, follow the block diagram.
NOTE. The inside front cover contains a full drawing showing how all the drive's function blocks
process input, output and control signals and how each block interfaces with the drive's overall control.
A more detailed software block diagram appears in the fold-out drawing at the end of Appendix D.
Appendix I list all the drive's parameters by tag number. Appendix J presents the same table in menu order and
Appendix K lists the parameters alphabetically.
Figure C.1 shows how to access the RAMPS function block through the MMI. Upon
power-up, the MMI displays the software version and then the message shown at the
top of the illustration. Pressing the "M" key changes the display to read the next block
down. The
▼
key changes the menu location from DIAGNOSTICS to SETUP PARAM-
ETERS. Pressing "M" again brings the display to the RAMPS menu. To change or
monitor any of the RAMPS parameters, press "M", then press
▲
or
▼
to scroll
through the RAMPS menu parameters.
The drive's parameters and function block inputs and outputs are defined as either a
percentage if they are continuous, or as boolean value (1 or 0) if they are discrete.
Depending on how the drive is configured, these parameters can represent physical
entities such as motor speed or current. Tagging function block inputs or outputs to
other software function blocks or to real world signals defines what the function block
inputs or outputs represent. For example, the output from RAISE/LOWER can
represent current demand if sent to the current loop or a speed setpoint if sent to the
speed loop.
