G7 ASD Operation Manual 1
Introduction
Congratulations on the purchase of the new G7 Adjustable Speed Drive (ASD). The G7 True Torque
Control2Adjustable Speed Drive is a solid-state AC drive that features True Torque Control2. TIC’s
Vector Control Algorithm enables the motor to develop high starting torque and provide compensation
for motor slip, which results in smooth, quick starts and highly efficient operation. The G7 uses digitally-
controlled pulse width modulation. The programmable functions may be accessed via the easy-to-use
menu or via the Direct Access Numbers (see pg. 48). This feature, combined with Toshiba’s high-
performance software, delivers unparalleled motor control and reliability.
The G7 is a very powerful tool, yet surprisingly simple to operate. The G7 has an easy-to-read 240 x 64
pixel graphical LCD screen with a user-friendly Electronic Operator Interface (EOI). The EOI provides
easy access to the many monitoring and programming features of the G7.
The motor control software is menu-driven, which allows for easy access to the motor control parameters
and quick changes when required.
To maximize the abilities of your new G7, a working familiarity with this manual will be required. This
manual has been prepared for the G7 ASD installer, user, and maintenance personnel. This manual may
also be used as a reference guide or for training. With this in mind, use this manual to develop a system
familiarity before attempting to install or operate the device.

2G7 ASD Operation Manual
Safety Precautions
Rotating shafts and electrical equipment can be hazardous. Installation, operation, and maintenance
shall be performed by Qualified Personnel only.
Qualified Personnel shall be:
•Familiar with the construction and function of the ASD, the equipment being driven, and the
hazards involved.
•Trained and authorized to safely clear faults, ground and tag circuits, energize and de-energize
circuits in accordance with established safety practices.
•Trained in the proper care and use of protective equipment in accordance with established safety
practices.
Installation of ASD systems should conform to the 1999 National Electrical Code Article 110
(NEC) (Requirements For Electrical Installations), all regulations of the Occupational Safety and
Health Administration, and any other applicable national, regional, or industry codes and
standards.
•Ensure that the Run functions (F, R, Preset Speed, etc.) of the ASD are off before performing a
Reset. The post-reset settings may allow the ASD to start unexpectedly.
•In the event of a power failure, the motor may restart after power is restored.
•Retry or Reset settings may allow the motor to start unexpectedly. Warnings to this effect
should be clearly posted near the ASD and motor.
DO NOT install, operate, perform maintenance, or dispose of this equipment until you have read
and understood all of the following product warnings and user directions. Failure to do so may result
in equipment damage, operator injury, or death.
Installation Precautions
•Use lockout/tagout procedures on the branch circuit disconnect before installing the ASD.
•Do Not mount the device in a location that would produce catastrophic results if it were to fall
from its mounting location (equipment damage or injury).
•Select a mounting location that is easily accessible by the user.
•Avoid installation in areas where vibration, heat, humidity, dust, metal particles, or high levels
of electrical noise (EMI) are present.
•Do not install the ASD where it may be exposed to flammable chemicals or gasses, water,
solvents, or other fluids.
•Always ground the unit to prevent electrical shock to personnel and to help reduce electrical
noise. The input, output, and control power cables are to be run separately and each shall have
its own ground cable.
Note: Conduit is not an acceptable ground.
•Ensure that the 3 phase input power isNot connected to the output of the ASD. This will destroy
the ASD and may cause injury to personnel.
•Do Not connect resistors across terminals PA –PC or PO –PC. This may cause a fire.
•Do not install the ASD if it is damaged or if it is missing component(s).
•Turn the power on only after attaching the front cover.
