Feature Overview
This document details differences between the GPD506/P5 and P7 product to assist in product transition and new product
introduction.
GPD506/P5 Drive
The GPD 506/P5 inverter is
intended for fan and pump
applications in Building and
Industrial Automation. It is
available in constant and
variable torque ratings, 3/4 to
500 horsepower.
P7 Drive
The P7 drive is an ideal choice for
industrial applications, such as
centrifugal fans and pumps. The
