GV3000E-AC008-AA-DBU RELIANCE

This instruction manual describes the GV3000/SE drive hardware. It does not coverthe GV3000/SE drive software. For software information, refer to the GV3000/SE ACGeneral Purpose (V/Hz) and Vector Duty Drive Software Start-Up and ReferenceManual (D2-3359).This manual is intended for qualified electrical personnel. It is organized according toa logical progression of steps to be followed to install and troubleshoot the drive.GV3000/SE drives will typically be referenced by horsepower in the manual. Ifadditional clarity is required, drive model numbers will also be included. 

Description:

This chapter provides an overview of the drive including how to identify the drive, adescription of the Regulator board, and the identification of major components of thedrive.The GV3000/SE AC drive is a PWM (pulse-width-modulated) drive that providesvector and general purpose regulation for a wide range of applications.Using vector regulation, the drive can provide high dynamic response, maintain fullrated motor torque to zero speed, and precisely control motor speed in bothdirections. The drive can provide this functionality either with encoder feedback (fluxvector 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 broadrange of applications requiring adjustable speed control of motors.

Each of the GV3000/SE drives have one of following NEMA ratings:• NEMA 1: Vented. Contains a communication access door that allows access to thecommunication port without removing the cover. Intended for general-purposeindoor applications.• NEMA 1A: Ventilated with fan and filter. Contains a communication access door thatallows access to the communication port without removing the cover. Intended forgeneral-purpose indoor applications.• NEMA 4X/12: Not vented. Supplied with base and keypad gaskets. Intended for usein indoor environments that require a water-tight/dust-tight enclosure. An enclosurewith this NEMA rating encompasses both ratings (4X and 12).• NEMA 12: Intended for use in indoor environments that require a dust-tight/drip-tightenclosure.See table 2.1 for a listing of the drives and their individual NEMA ratings.
