3 Product Overview
‹ About This Product
Yaskawa has simplified the application of variable frequency drives to pumping applications. Pumps are typically used
whenever water must be pumped from deep water wells or open bodies of water such as rivers, lakes, irrigation canals,
and water storage facilities. The integrated pump specific software and quick setup parameters, allow the operator easy
access to setup control values for a wide range of applications.
„ Feature Enhancement Summary
The following is a brief summary of features for drive software PRG:0035 that are added or enhanced over previous
iQpump Controllers:
Initialization Function: A special initialization function is created to quickly and conveniently configure the drive as a
generic speed controller. This initialization re-configures the Pump Quick Setup (Quick Start) menu to show parameters
likely to require adjustment in generic applications.
b1-04 (Reverse Operation Selection): Added new parameter B1-04 (Reverse Operation Selection) which allows the
motor phases to be exchanged.
FCarrier Frequency Selection (C6-02): Default has been changed to 1 (2.0 kHz).
Remote Drive Disable: This feature prohibits the drive from running when a new multifunction digital input is closed for
a set amount of time.
Low City Pressure Alarm Selection: Added a parameter that selects the Low City Pressure alarm text that will show
when in a Low City Pressure condition.
Suction Control Support via the Constant Pressure with Well Draw Down Control: Suction control option has been
integrated into the Water Level control.
Modified Terminal A1 Loss Detection: Different alarm/fault texts will occur when feedback loss is detected on
Terminal A1 to differentiate from PI feedback loss on Terminal A2.
iQpump Memobus Multiplex: Lag Drive Speed Follower: Lag drives follow the speed of the lead drive.
iQpump Memobus Multiplex: Lag Turn Off: Lag drives can run at a fixed speed for a set time before turning off.
iQpump Memobus Multiplex: Flow Meter: New option to stage or de-stage based on Flow Rate.
iQpump Memobus Multiplex: Stop History: A new lead drive selection (P1-01) option has been added.
Geothermal Mode: The speed of the drive is determined by an analog temperature input and a temperature-speed curve.
iQpump Multiplex: Water Level/Suction Pressure Control
• Ability to run the iQpump Controller Memobus network with just 1 drive connected to a Water Level or Suction
Pressure device
• Ability to automatically switch from the Analog Water Level/Suction Pressure Source to the Network Source in case of
transducer loss or wire breaks.
• Pump De-stage due to the Water Level being below the Minimum Water Level.
• Pump De-stage due to the Suction Pressure being below the Minimum Suction Pressure.
• Disallow Pump Staging when PI is being influenced by the Water Level/Suction Pressure control
