The planned usage of the overall
system will determine which options
and control methods are
appropriate, as well as how the VFD
should be installed and
programmed. Refer to the following
pages for examples of how the
system might be used.
System options define and automate
features that support the intended
operation. These features may
require specialized control methods
and programming. For more details,
refer to “Drive Configuration” on
page 24, and “Performance
The SubDrive Utility supports
several methods for automating
pump motor speed control. Refer to
“Drive Configuration” on page 24
for possible control setups.
The overall function of the system
directly affects where and how the
VFD should be mounted. Refer to
“Physical Installation” on page 16 for
guidelines.
The selected motor application,
along with the control method(s),
determines how the VFD should be
connected. Refer to “Electrical
Installation” on page 18 for more
information.
The VFD can be quickly and easily
programmed for most standard
operations. Refer to “Drive
Configuration” on page 24. Advanced
features or options may require
additional adjustments to achieve the
desired performance. Refer to
