4G7 ASD Quick Start Guide

Installation and Connections

The G7 True Torque Control2Adjustable Speed Drive may be set up initially by performing a few

simple configurationsettings. To operate properly, the ASD must be securely mounted and connected to

a power source (3-phase AC input at the L1/R, L2/S, and L3/T terminals). The control terminals of the

ASD may be used by connecting the terminals of the Control Terminal Strip to the proper sensors or

signal input sources (see the section titled I/O and Control on pg. 8).

Note: The optional ASD-Multicom boards may be used to expand the functionality of the

ASD. See the G7 ASD Operation Manual (P/N 51546) or contact your TOSHIBA sales

representative for additional information on the available G7 ASD options.

The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor that is to be

controlled (see Figure 4 on pg. 9).

Upon initial system powerup, the Startup Wizard starts automatically. The Startup Wizard assists the

user with the initial configuration of the G7 True Torque Control2Adjustable Speed Drive. See the

section titled Initial Setup on pg. 12 for additional information on the Startup Wizard.

As a minimum, the installation of the ASD shall conform to Article 110 of the 2002 NEC, the

Occupational Safety and Health Administration requirements, and to any other local and regional

industry codes and standards.

Installation Notes

When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at

startup because of insufficient voltage. To avoid this, Do Not connect the brake or the brake contactor to

the output of the ASD.

If an output contactor is used for bypass operation,it must beinterlocked such that commercial power is

never applied to the output terminals of the ASD (T1/U, T2/V, or T3/W).

If a secondary magnetic contactor (MC) is used between the output of the ASD and the motor, it should

be interlocked such that the ST – CC terminals are disconnected before the output contactor is opened.

Do Not open and then close a secondary magnetic contactor between the ASD and the motor unless the

ASD is off and the motor is not rotating.

Note: Re-application of power via a secondary contact while theASD is on or while the motor

is still turning may cause ASD damage.

On some devices the ST-to-CC connection is further enhanced by the operation of the MS1 AUX relay

circuit. The MS1 AUX relay circuit is normally open and closes the ST-to-CC connection only after

normal system power is available. The MS1 AUX relay circuit prohibits the ST-to-CC connection in

the event that the MS1contactor fails to close during start up or if MS1opens while the ASD is running.

For the 200 volt ASD this feature is available on the 30 HP system, on the 460 volt ASD this feature is

available on the 50 HP and above systems, and on the 600 volt ASD it is available on the 60 HP and

above systems.

Figure 1. MS1 AUX Circuit Configuration.

G7 ASD Quick Start Guide 5

The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages

approaching the upper or lower limit settings may require that the overvoltage and undervoltage stall

protection level parameters, F626 and F629, be adjusted. Voltages outside of the permissible tolerance

should be avoided.

The input power frequency should be ±2 Hz of the specified input frequency.

Do not use an ASD with a motor that has a power rating that is higher than the rated output of the ASD.

The ASD is designed to operate NEMA B motors. Consult with your sales representative before using

the ASD for special applications such as with an explosion-proof motor or applications with a piston

load.

Do Not apply commercial power to the output terminals T1/U, T2/V, or T3/W.

Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.

Interface problems may occur when this ASD is used in conjunction with some types of process

controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact

your TOSHIBA sales representative or the process controller manufacturer for additional information

about compatibility and signal isolation).

Use caution when setting the output frequency. Over speeding a motor decreases its ability to deliver

torque and may result in damage to the motor and/or the driven equipment.

All G7 ASDs are equipped with internal DC bus fuses. However, not all G7 ASDs are equipped with

internal primary power input fuses (HP dependent). When connecting two or more drives that have no

internal fuse to the same power line as shown in Figure 2, it will be necessary to select a circuit-

breaking configuration that will ensure that if a short circuit occurs in ASD 1, only MCCB2 trips, not

MCCB1. If it is not feasible to use this configuration, insert a fuse between MCCB2 and ASD 1.

Mounting the ASD

Install the unit securely in a well ventilated area that is out of direct sunlight using the four mounting

holes on the rear of the ASD.

The ambient temperature rating for the G7 is from 14 to 104° F (-10 to 40° C). The process of

converting AC to DC, and then back to AC produces heat. During normal ASD operation, up to 5% of

the input energy to the ASD may be dissipated as heat. If installing the ASD in a cabinet, ensure that

there is adequate ventilation.

Do Not operate the ASD with the enclosure door open.

When installing multiple ASDs, ensure that there is a clearance space of at least 8 inches (20 cm) from

the top and the bottom of adjacent units. There should be at least 2 inches (5 cm) on either side of

adjacent units. For the models below 50 HP the top and bottom clearance specifications may be reduced

to 4 inches (10 cm). This space ensures that adequate ventilation is provided (see the section titled

Enclosure Dimensions/Weight on pg. 33 for additional information on mounting space requirements).

Note: Ensure that the ventilation openings are not obstructed.

6G7 ASD Quick Start Guide

ASDs produce high-frequency noise — steps must be taken during installation to avoid the negative

effects of noise. Listed below are some examples of measures that will help to combat noise problems.

• Separate the input and output power conductors of the main circuit. Do not install the input and

output wires in the same duct or in parallel with each other, and do not bind them together.

• Do not install the input or output power conductors of the main circuit and the wires of the control

circuit in the same duct or in parallel with each other, and do not bind them together.

• Use shielded wires or twisted wires for the control circuits.

• Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.

• Connect a surge suppressor to every electromagnetic contactor and every relay installed near the

ASD.

• Install noise filters as required.

Connecting the ASD

Refer to the section titled Installation Precautions on pg. 1 and the section titled Lead Length

Specifications on pg. 7 before attempting to connect the ASD and the motor to electrical power.

System Grounding

Proper grounding helps to prevent electrical shock and to reduce electrical noise. The ASD is designed

to be grounded in accordance with Article 250 of the 2002 NEC or Section 10/Part One of the

Canadian Electrical Code (CEC).

The grounding conductor shall be sized in accordance with Article 250-122 of the NEC or Part One-

Table 6 of the CEC.

Note: The metal of conduit is not an acceptable ground.

The input, output, and control lines of the system shall be run in separate metal conduits and each shall

have its own ground conductor.

Power Connections

L1/R, L2/S, and L3/T are the 3-phase input supply terminals for the ASD. The ASD may be operated

from a single-phase supply. When operating using a single-phase supply, use the L1 and L3 terminals.

T1/U, T2/V, and T3/W are the output terminals of the ASD that connect to the motor.

An inductor may be connected across terminals PA and PO to provide additional filtering. When not

used, a jumper is connected across these terminals (see Figure 4 on pg. 9).

Connect the input and output power lines of the ASD as shown in Figure 3.

Note: In the event that the motor rotates in the wrong direction when powered up, reverse any

two of the three ASD output power leads connected to the motor.
