2.0 ABOUT THE DRIVE
2.1
This chapter describes how to identify the drive using the model number matrix and illustrates the
differences between the NEMA enclosures. Major components of each drive group are also shown.
The GV3000 A-C drive is a PWM drive that provides vector and general purpose (volts/hertz or V/Hz)
regulation for a wide range of applications.
Using vector regulation, the drive can provide high dynamic response, maintain full rated motor
torque to zero speed, and precisely control motor speed in both directions using pulse tachometer
feedback.
Using general purpose (volts/hertz) regulation, the drive is suited for a broad range of applications
requiring adjustable speed control of motors.
Identifying the Drive by Model Number
Each GV3000 A-C drive can be identified by its model number. See figure 2.1. This number appears
on the shipping label and on the drive's nameplate. The drive's model number includes the Power
Module and the regulator. Drive power ratings are provided in table 2.1.
