VLP TECHNOLOGY MAKES PID TUNING
A THING OF THE PAST
Toshiba's breakthrough VLP algorithm has taken PID and made it obsolete, completely reinventing how users control
pressure or flow. With this new technology, after simply inputting a few values into the Q9 Plus, optimum control is attained.
Toshiba's VLP Setup Wizard effortlessly guides the user through the entire process.

UNIT OPTIONS
Toshiba allows users to "build your own drive" by includ-
ing several popular options as standard choices for custom
packages. Configuration options include line reactors for in-
put power-conditioning and harmonic mitigation as well as
the choice between two- or three-contactor bypasses to al-
low for across-the-line motor operation.
"Build Your Own Drive" packages use a standard NEMA 1
enclosure and are available with the following options:
• Input Circuit Breaker
• Two-Contactor Bypass
• Three-Contactor
Isolated Bypass
APPLICABLE APPLICATIONS:
• Air Handling
• Chill Water Circulation
Q9 PLUS ASD
The setup process defines the operating boundaries by establishing a
minimum VLP point and a maximum VLP point. By defining the minimum and
maximum points, VLP creates an operating domain within the drive that is
directly and proportionately related to the specific pumping system to which
it is connected.
Once VLP points have been established, the Q9 Plus performs the following
functions:
• Monitors Multiple Systems for Friction Losses, Impeller Variations,
& Other System Variables
• Adjusts System Accordingly to Ensure Only Necessary Fans
