Virtual Linear Pump Setup
Toshiba International Corporation’s Virtual Linear Pump algorithm allows for direct and precise
control of pressure, flow rate, or level. This is achieved without the concerns, instabilities, or
complexities that are traditionally associated with pumping system control.
This section provides useful setup and operational information for the Virtual Linear Pump system.
The system is initially configured using the (Program Virtual Linear Pump ) Virtual Linear
Pump Setup Wizard. Once the Wizard is started, it must be completed for normal Virtual Linear
Pump operations to function.
However, the parameters addressed while using the Wizard or the Virtual Linear Pump Settings menu
selection are also accessible via their associated direct access numbers for specific adjustments when
required.
If not using the Wizard to configure the settings of the Virtual Linear Pump algorithm, parameter
F911 must first be set to 255: Virtual Linear Pump to accept the new or changed Virtual Linear
Pump parameter settings. Upon completion of the parameter changes, set parameter F911 to 1 or 2 to
use the changed (new) settings for normal Virtual Linear Pump operations (Zero may be selected at
F911 to save the changes to be used later).
The setup procedure and the Wizard setup screens are shown below.
Figure 29. Input the Electrical Specifications of the Motor.
Figure 30. Input the Specifications of the Transducer.
1.Enter the FLA from the
nameplate of the motor.
2.Select Pressure or Level.
3.Select the command source:
EOI or V/I analog input.
4.Set the Low Frequency
Limit. 15 Hz fits most
applications.
5.Click Next to continue.
6.Set the unit of measure for
the transducer: pressure,
flow rate, or level (i.e., PSI,
GPM, Inches of Water
Column, Feet of Water
Column, or Cubic Feet per
Minute).
7.Select the transducer output
range and signal type:
Current or Voltage.
8.Set the full-scale reading of
the transducer.
9.Click Next to continue.
