Reliance Electric GV3000/SE AC Drive
This chapter provides an overview of the drive including how to identify the drive, a description of the Regulator board, and the identification of major components of the drive. The GV3000/SE AC drive is a PWM (pulse-width-modulated) drive that provides vector and general purpose 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. The drive can provide this functionality either with encoder feedback (flux vector control or FVC) or without (sensorless vector control or SVC). Using general purpose (volts/hertz or V/Hz) regulation, the drive is suited for a broad range of applications requiring adjustable speed control of motors.
Each GV3000/SE AC 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
