Introduction
Congratulations on the purchase of the new
P9 Adjustable Speed Drive
!
The
P9 Adjustable Speed Drive
(ASD) is a solid-state AC drive that features Toshiba International
Corporation’s (TIC) new
Virtual Linear Pump
function. The
VLP
algorithm was designed to remove
the guess work that is associated with the setup of pumping systems. The
VLP
algorithm allows for
precise, linear, and consistent pump curve responses at any flow or pressure setting!
The
Virtual Linear Pump
function allows for direct and precise pumping system control. This is
accomplished without the normal concerns of the adverse effects of conventional pumping system
control response curves.
Toshiba’s
VLP
algorithm is further enhanced by the introduction of the new
Time-Based Alternation
(TBA) function!
Time-Based Alternation
optimizes load sharing and offers a significantly decreased
level of system down-time.
Time-Based Alternation
provides a more evenly-spread machine wear pattern for all motors and
pumps of the system. Load sharing is optimized by allowing all pumps to alternate as the primary pump
while the remaining pump(s) operate in an ancillary mode for time intervals that are determined by the
user.
The decreased system down-time is realized in the event of a failure of one or more pumps, when
seamlessly, the system continues to operate, albeit with a diminished capacity.
Using
VLP
and
Time-Based Alternation
, the system seamlessly and easily adapts to peak load
demands while maintaining the same degree of high performance and reliability output across the entire
load range - without any user intervention!
The
VLP
and
Time-Based Alternation
algorithms coupled with Toshiba International Corporation’s
Vector Control Algorithm
provides setup ease, enhanced reliability, and precise control under the most
demanding conditions. All while enabling the motors of the system to develop high starting torque and
provide compensation for motor slip, which results in smooth, quick starts, and highly efficient
operation.
The programmable functions may be accessed via the easy-to-use menu or via the Direct Access
Numbers (See the
P9 ASD Installation and Operation Manual DN 64054
). This feature, combined with
Toshiba International Corporation’s high-performance software, delivers unparalleled motor control,
reliability, and ease of use.
The P9 is a very powerful tool, yet surprisingly simple to operate. The user-friendly
Electronic
Operator Interface
(EOI) of the P9 has an easy-to-read LCD screen. There is also a high-visibility
LED screen that can be read from a greater distance. The EOI provides easy access to the many
monitoring and programming features of the P9.
To maximize the abilities of your new P9, a working familiarity with this guide is required. This guide
has been prepared for the ASD installer, user, and maintenance personnel. This guide may also be used
as a reference guide or for training. With this in mind, use this guide to develop a familiarity with the P9
before attempting to install, operate, or perform maintenance on the device.
