Introduction
Congratulations on the purchase of the P9 Adjustable Speed Drive!
The P9 Adjustable Speed Drive (ASD) is a solid-state AC drive that features Toshiba International
Corporation's (TIC) Virtual Linear Pump Technology, Time-Based Alternation, and Vector
Control algorithms. These algorithms provide easy setup, enhanced reliability, and precise control
under the most demanding conditions — all while enabling the motors of the system to develop high
starting torque and providing compensation for motor slip. The result is smooth, quick starts and highly
efficient operation.
Virtual Linear Pump Technology was designed to remove the guesswork that is normally associated
with the setup of pumping systems. It allows for pump curve responses that are direct, linear, and
precise at any flow or pressure setting. Eliminating the normal concerns of the adverse effects of
conventional pumping system control response curves, Virtual Linear Pump Technology allows the
system to adapt seamlessly to peak load demands while maintaining the same degree of high
performance output and reliability across the entire load range — all without any user intervention!
Time-Based Alternation provides a more evenly-spread machine wear pattern for motors and pumps
of the system by optimizing load sharing such that all pumps are allowed 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. Time-Based Alternation also offers a significantly decreased level of system down-time in
the event of a pump failure, when the system continues to operate, albeit with a diminished capacity.
The P9 ASD is a very powerful tool, yet surprisingly simple to operate. The user-friendly Electronic
Operator Interface (EOI) of the P9 ASD has an easy-to-read LCD screen and a high-intensity LED
display. The EOI provides easy access to the many monitoring and programming features of the P9
ASD. The programmable functions may be accessed via the easy-to-use menu or via the Direct Access
Numbers (see pg. 77). This feature, combined with high-performance software, delivers unparalleled
motor control, reliability, and ease of use.
This manual has been prepared for the P9 ASD installer, user, and maintenance personnel. This manual
may also be used as a reference guide or for training. To maximize the abilities of your P9 ASD, use this
manual to develop a system familiarity before attempting to install, operate, or perform maintenance on
the device.
