Introduction
Congratulations on the purchase of the GX7R Active Front End Adjustable Speed Drive!
The GX7R Active Front End Adjustable Speed Drive (ASD) is a configurable solid-state AC drive
that features Toshiba International Corporation’s (TIC) Vector Control algorithm and the
Regeneration capability.
The Regeneration capability comes into play when the motor slip is positive and the torque is negative
(i.e., decelerating load or overhauling load). The properly configured ASD converts the energy
produced by the negative torque of the load into 3-phase AC energy that is returned to the municipal
supplier automatically.
The active front end of the GX7R ASD is required to support the Regeneration function and
significantly contributes to the mitigation of harmonic distortion and an increased power factor.
The GX7R ASD is a very powerful tool, yet surprisingly simple to operate. The user-friendly
Electronic Operator Interface (EOI) of the GX7R ASD has an easy-to-read LCD screen. The EOI
provides easy access to the many monitoring and programming features of the GX7R ASD.
The GX7R ASD uses digitally-controlled pulse width modulation (PWM). The programmable PWM
functions may be accessed via the easy-to-use menu or via the Direct Access Numbers (see the GX7R
ASD Install and Op Manual).
This feature, combined with Toshiba’s high-performance software, delivers unparalleled motor control
and reliability.
To maximize the abilities of your GX7R ASD, a working familiarity with this guide will be required.
This guide has been prepared for the GX7R ASD installer, user, and maintenance personnel. This guide
may also be used as a reference guide or for training. With this in mind, use this guide to develop a
system familiarity before attempting to install, operate, or perform any maintenance on the device.

WARNING

8GX7R ASD Quick Start Guide
System Setup Requirements
• When using the ASD as an integral part of a larger system, it is the responsibility of the ASD
installer/maintenance personnel to ensure that there is a fail-safe in place (i.e., an arrangement
designed to switch the system to a safe condition if there is a fault or failure).
• Power factor improvement capacitors or surge absorbers MUST NOT be installed on the three-
phase output of the ASD.
• Use of the built-in system protective features is highly recommended (i.e., Emergency Off,
Overload Protection, etc.).
• The operating controls and system status indicators shall be clearly readable and positioned where
they may be viewed without obstruction.
• Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.
• System safety features shall be employed and designed into the integrated system in a manner such
that system operation, even in the event of system failure, will not cause harm or result in system
damage or injury to personnel (i.e., Emergency Off, Auto-Restart settings, System Interlocks, etc.).
• The programming setup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Auto-Restart and Retry settings is a requirement to use this
product.
• The setup procedures included within this guide may require a Reset before performing the
procedure. Application-specific settings may then be performed. The pre-Reset conditions may be
saved (see F007).
• There may be thermal or physical properties, or ancillary devices integrated into the overall system
that may allow for the ASD to start the motor without warning. Warning signs to this effect must be
clearly posted at or near the machinery/hazard.
• If a secondary magnetic contactor (MC) or an ASD output disconnect is used between the ASD and
the load, it should be interlocked to halt the ASD before the secondary contact opens. If the output
contactor is used for bypass operation, it must be interlocked such that commercial power is never
applied to the ASD output terminals (U, V, or W).
• When using an ASD output disconnect, the ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output of the
ASD is active may result in equipment damage or injury to personnel.
CAUTION

GX7R ASD Quick Start Guide 9
Operational and Maintenance
Precautions
• Turn off and lock-out/tag-out the main power, the control power, and instrumentation connections
before inspecting or servicing the ASD, removing any enclosure panels, or connecting/
disconnecting the power wiring to the equipment.
• If/when taking a live reading is required (equipment is powered), it is to be performed by Qualified
Personnel ONLY. Proper and approved personal protection equipment is to be used by trained
personnel for all electrical measurements.
• The capacitors of the ASD maintain a residual charge for a period of time after the ASD is powered
off. The required time for each ASD typeform is indicated with a cabinet label and a Charge
Indicator LED (see Figure 1. on pg. 12). Wait at least the minimum time indicated on the
enclosure-mounted label and ensure that the Charge Indicator LED has gone out once the ASD
power has been turned off before coming into contact with any circuits.
• Turn the power on only after attaching (or closing) the front cover. DO NOT open or remove the
front cover or any of the enclosure panels of the ASD when the power is on.
•DO NOT attempt to disassemble, modify, or repair the ASD. Contact the Toshiba Customer
Support Center for repair information.
•DO NOT place any objects inside of the ASD.
• If the ASD should emit smoke, or an unusual odor or sound, turn off the power immediately.
Note: Heated precharge resistors produce a unique smell upon the initial commissioning of
an ASD. This is normal and will subside upon the first few hours of ASD operation.
• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool
before coming in contact with these items.
•TheAuto-Restart and Retry programmable functions of the ASD may allow for the system to
start or stop unexpectedly. Warning signs to this effect must be clearly posted at or near the
machinery/hazard.
• Remove power from the ASD during extended periods of non-use.
• Inspect the system annually (as a minimum) for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely. Inspect more frequently when
operating in a harsh environment or when used on a high-output-demand application.
DANGER

10 GX7R ASD Quick Start Guide
Installation and Connections
The GX7R ASD may be set up initially by performing a few simple configuration settings. To operate
properly, the ASD must be connected to a power source. Connect the 3-phase AC input lines, C-B-A, to
the PB1 terminal block terminals A, B, and C, respectively.
The control terminals of the ASD may be used by connecting the terminals of the Motoring Terminal
Board (P/N 48570) to the proper sensors or signal input sources (see the section titled I/O and Control
on pg. 16 and Figure 5. on pg 20).
Note: The optional ASD-Multicom boards may be used to expand the I/O functionality of
the ASD. See the GX7R ASD Install and Op Manual for more information on the
available options.
Note: The GX7R ASD uses two control boards and two terminal boards; Motoring and
Regeneration. Unless otherwise specified, the terms Control Board and Terminal
Board refer to the Motoring Control and the Motoring Terminal Boards.
The output terminals of the ASD (T1, T2, and T3) must be connected to the motor that is to be
controlled (see Figure 18. on pg 28).
As a minimum, the installation of the ASD shall conform to Article 110 of the NEC, the Occupational
Safety and Health Administration requirements, and to any other local and regional industry codes
and standards.
The Startup Wizard assists with the initial configuration of the commonly used GX7R ASD
parameters. See the section titled Startup Wizard on pg. 32 for additional information on the Startup
Wizard. The Startup Wizard is launched by configuring the system to start the wizard automatically
upon a system restart.
Installation Notes
Do Not apply commercial power to the output terminals T1, T2, or T3.
If an output contactor is used for bypass operation, it must be interlocked such that commercial power is
never applied to the output terminals of the ASD (T1, T2, or T3).
If a secondary magnetic contactor (MC) is used between the output of the ASD and the motor, it should
be interlocked in series with the ST – CC connection such that the ST – CC connection is 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 the ASD is on or while the
motor is still turning may cause ASD damage.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
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.
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 (via ST1)
CAUTION

GX7R ASD Quick Start Guide 11
only after normal system power is available. The MS1 AUX relay circuit prohibits the ST-to-CC
connection in the event that the MS1 contactor fails to close during start up or if MS1 opens while the
ASD is running.
The ASD input voltage should remain within 10% of the specified input voltage. The frequency of the
input power should be ±2 Hz of the specified input frequency.
The ASD is designed to operate NEMA B motors. Consult with the Toshiba Customer Support Center
before using the ASD for special applications such as with an explosion-proof motor or applications
with a piston load.
Interface problems may occur when an ASD is used in conjunction with some types of process
controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact the
Toshiba Customer Support Center 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 GX7R ASDs are equipped with internal DC bus fuses. In the event that a DC bus fuse opens, the
Bus Fuse Open Indicator LED of the Gate Driver board turns on (see Figure 1. on pg 12).
All GX7R ASDs are equipped with semiconductor fuses and a breaker.
Installing the ASD
Install the unit securely to the floor in a well ventilated area.
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.
Do Not operate the ASD with the enclosure door open or with any enclosure panels removed.
