ATTENTION: The custom firmware is designed for a specific application and load condition. It differs from the
standard PowerFlex 700 Vector Control product offering and must be installed and run only under this custom
application. Attempting to run this custom firmware under any other type of application can result in
unpredictable and/or hazardous conditions.
ATTENTION: The drive contains parts and assemblies that are sensitive to electrostatic discharge (ESD). Static
control precautions are required when installing, testing, servicing, or repairing parts and assemblies.
Component damage can result if ESD control procedures are not followed. If you are not familiar with static
control procedures, refer to Guarding Against Electrostatic Damage Data Sheet, publication 8000-4.5.2, or
other applicable ESD protection handbook.
The PowerFlex 700 sensorless pump off function is an enhancement to the basic pumpjack oil
well application. The pump off function detects when the fluid level in a well drops.
Programming then determines if the drive slows down or stops pumping. The low level detection
is accomplished by an algorithm that utilizes dynamic motor data, thereby removing the need for
external sensors. Productivity can be increased by detecting a low well condition and pumping at
a slower rate during the "pump off " condition rather than simply running the pump on a timer.
