Introduction
This Section describes the applicability of the Manual
The P7 Drive is a Pulse Width Modulated Drive for 3-Phase AC induction motors. This type of Drive is also known as an
Adjustable Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD, and Inverter. In this manual, the P7
Drive will be referred to as the “Drive”.
The Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation, including fans,
blowers and pumps. A new benchmark for size, cost, performance, benefits, and quality, the Drive includes numerous
built-in features such as network communications, PI, parameter storage and copy functions.
The Drive has embedded communications for Modbus
®
protocol. An optional L ON W ORKS
®
interface card is also available.
The LCD keypad/operator is equipped with local/remote functions, copy feature, 7 language choices, and 5 lines of display
with 16 characters per line. User parameter settings can be recovered at any time via “user initialization”. Optional software
allows upload/download, as well as graphing and monitoring of drive parameters from a PC for ease of drive management.
Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes feedback
display, inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and
pumps for pressure, flow, or temperature regulation.
