The information in the user’s manual is subject to change without notice.
ONLY QUALIFIED ELECTRICAL PERSONNEL FAMILIAR WITH THE CONSTRUCTION AND
OPERATION OF THIS EQUIPMENT AND THE HAZARDS INVOLVED SHOULD INSTALL, ADJUST,
OPERATE, OR SERVICE THIS EQUIPMENT. READ AND UNDERSTAND THIS MANUALAND OTHER
APPLICABLE MANUALS IN THEIR ENTIRETY BEFORE PROCEEDING. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.
THE USER IS RESPONSIBLE FOR CONFORMING WITH ALL APPLICABLE LOCAL, NATIONAL, AND
INTERNATIONAL CODES. WIRING PRACTICES, GROUNDING, DISCONNECTS, AND
OVERCURRENT PROTECTION ARE OF PARTICULAR IMPORTANCE. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.
D-C BUS CAPACITORS RETAIN HAZARDOUS VOLTAGES AFTER INPUT POWER HAS BEEN
DISCONNECTED. AFTER DISCONNECTING INPUT POWER, WAIT FIVE (5) MINUTES FOR THE D-C
BUS CAPACITORS TO DISCHARGE AND THEN CHECK THEVOLTAGE WITH A VOLTMETER TO
ENSURE THE D-C BUS CAPACITORS ARE DISCHARGED BEFORE TOUCHING ANY INTERNAL
COMPONENTS. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE BODILY
INJURY OR LOSS OF LIFE.
THE DRIVE IS CAPABLE OF OPERATING AT AND MAINTAINING ZERO SPEED. THE USER IS
RESPONSIBLE FOR ASSURING SAFE CONDITIONS FOR OPERATING PERSONNEL BY PROVIDING
SUITABLE GUARDS, AUDIBLE OR VISUAL ALARMS, OR OTHER DEVICES TO INDICATE THAT THE
DRIVE IS OPERATING OR MAY OPERATE AT OR NEAR ZERO SPEED. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.
WARNING
THE USER MUST PROVIDE AN EXTERNAL, HARDWIRED EMERGENCY STOP CIRCUIT OUTSIDE OF
THE DRIVE CIRCUITRY. THIS CIRCUIT MUST DISABLE THE SYSTEM IN CASEOF IMPROPER
OPERATION. UNCONTROLLED MACHINE OPERATION MAY RESULT IF THIS PROCEDURE IS NOT
FOLLOWED. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN BODILY INJURY.

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 usingpulse 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 canbe 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.

2.2 NEMA Enclosures
Each of the GV3000 Power Modules have one of following NEMA ratings:
@ NEMA 1: Vented. Contains a communication access door that allows access to the
communication port without removing the cover. Intended for general-purpose indoor
applications.
e NEMA 4X/12: Not vented. Supplied with base and keypad gaskets. Intended for use in indoor
environments that require a water-tight/dust-tight enclosure. An enclosure with this
NEMA rating encompasses both ratings (4X and 12).
e@ NEMA 12: Intended for use in indoor environments that require a dust-tight/drip-tight enclosure.
See table 2.1 for a listing of the Power Modules and their individual NEMA ratings.

2.7 Regulator Board Description
GV3000 drive regulation is performed bya microprocessor on the Regulator board. See figures 2.8
and 2.9. Drive operation is adjusted by the parameters entered through the keypad. The Regulator
board accepts power circuit feedback signals, an external speed reference signal, and internal heat
sensor feedback, as well as data from a pulse tachometer that is attached to the motor when set up
for vector regulation. The Regulator board provides:
PWM gating signals to the IGBT power devices
Based on the output of the control loop, the regulator sends PWM gating signals through the
Current Feedback board to isolated drivers on the Gate Driver board. These drivers switch the
Insulated Gate Bi-polar Transistors (IGBTs), producing a Pulse Width Modulated (PWM) waveform
that corresponds to the speed (vector regulation) or frequency (volts/hertz regulation) reference.
The IGBTs can be switched at either a 2, 4 or 8 kHz carrier frequency.
Form A and B contacts for drive status indicators
The Form A and B contacts are under control of the user via programmable parameters. A Form A
or B transition can indicate drive status. The contacts are rated for 5 Amps resistive load at 250
VAC/ 30 VDC and are made available through the terminal strip.
Display data for a four-character display and fourteen indicator LEDs
The four-character display is used to indicate drive parameters, parameter values, and fault
codes. The fourteen single LEDs indicate drive status and mode, as well as identifying drive
outputs whose values are displayed on the four-character display.
An analog output
The analog output is a scaled voltage (0-10 VDC) or current (4-20 mA) signal proportional to
either motor speed (RPM) or motor torque or current (%TORQUE). The current selection (via
jumper J17) requires a power supply for operation. The power can be sourced from the pulse
tachometer terminals (4 and 9) or from an external 15V power supply. See table 7.1, terminals 10
and 11, for more information. The analog output signal is available through the terminal strip.
A snubber resistor braking signal
The 1-60 HP regulator provides a signal for use by an optional snubber resistor braking kit. The
signal goes through an isolating driver, made available through the terminal strip.
Two Regulator boards are usedon the GV3000 drives: 1-60 HP Regulator boards are used with
1-60 HP drives; 60-150 HP Regulator boards are used with 60-150 HP drives. As shown in figures 2.8
and 2.9, the Regulator boards are similar but have different Power Module interface connectors.
