VLT Drive and Cascade Controller Setup
Introduction
A new quick menu list is activated when a cascade
controller option card is installed in the VLT adjustable
frequency drive. The original 12 items are expanded
to 39 quick menu items that allow programming
additional drive and cascade controller functions.
See Chapter 4, Changed Drive Functions.
The first 20 items on the new quick menu must
be programmed in sequence for initial drive and
cascade controller setup. (See block diagram.) These
20 items are common to both Standard cascade
control mode and Master/Slave control mode. After
initial setup is complete, additional quick menu
items program the drive for the selected mode of
operation. Those instructions are available in Chapter
7, Standard Cascade Control Mode Setup and
Chapter 8, Master/ Slave Control Mode Setup.
Chapter 9, System Optimization, provides instructions
for final adjustments to reach maximum drive and
controller efficiency after system start up.
Items 2 6 are motor characteristics. In Standard
cascade control mode, only the motor data from the
variable speed motor run by the cascade controller
are entered. In Master/Slave control, only data from
the motor controlled by the Master drive are entered
at this time. Items 7 19 are basic cascade controller
settings used in either mode of operation. Item 20
28
Cascade Controller Option
selects the mode of operation for further setup.
The Quick Menu Summary table on the next
page describes the menu items.
The VLT adjustable frequency drive has four
independent setups that can be programmed.
The initial programming in this chapter is stored
as Setup 1. See Alternative Programming at
the end of this chapter for instructions on using
the drives multi-setup capability.
VLT drives delivered with the cascade controller
option card already installed, or prepared for field
installation, have been programmed with factory
settings typical for operation. These settings may be
satisfactory for initial start up of the system.
See Chapter 5, Use Interface, for instructions
on programming the VLT drive.
