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.

G7 ASD Quick Start Guide 7
Connect the 3-phase input power to the input terminals of the ASD at L1/R, L2/S, and L3/T. Connect
the output of the ASD to the motor from terminals T1/U, T2/V, and T3/W. The input and output
conductors and terminal lugs used shall be in accordance with the requirements listed in Appendix D on
pg. 47.
If conductors smaller than the recommended sizes are used in parallel for the input or output power,
each branch of the parallel set shall have its own conduit and not share its conduit with other parallel
sets (i.e., place U1, V1, and W1 in one conduit and U2, V2, and W2 in another).
Note: National and local codes should be referenced when running more than three
conductors in the same conduit.
Install a molded case circuit breaker (MCCB) or fuse between the3-phase power source and the ASD in
accordance with the 2002 NEC Article 430-102 through 430-111 and the fault current setting of the
ASD.
For 600 volt ASDs, the 15 HP or less drives (P/N VT130G7U6015 – 6160) require a class-J fuse rated
at 600 Volts/30 A.
Lead Length Specifications
Adhere to the NEC and any local codes during the installation of ASD/Motor systems. Excessive lead
lengths may adversely effect the performance of the motor. Special cables are not required. Lead lengths
from the ASD to the motor in excess of those listed in Table 1 may require filters to be added to the output
of the ASD. Table 1 lists the suggested maximum lead lengths for the listed motor types.
Contact TOSHIBA for application assistance when using lead lengths in excess of those listed.
Exceeding the peak voltage rating or the allowable thermal rise timeof the motor insulation will reduce
the life expectancy of the motor.
For proper operation, the carrier frequency must be 2.2 kHz or above except when operating in the
Constant Torque, Variable Torque, or the 5-Point Setting modes.
Startup and Test
Perform the following checks before turning on the unit:
•L1/R, L2/S, and L3/T are connected to the 3-phase input power.
•T1/U, T2/V, and T3/W are connected to the motor.
• The 3-phase input voltage is within the ASD setup tolerances.
• There are no shorts and all grounds are secured.

Default Setting Changes
To change a default parameter setting, press ESC until the screen toggles to and from the Frequency
Command screen and the Panel Menu. From the Frequency Command screen, go to the Program
mode by pressing the MON/PRG key twice and the Program menu is displayed. Turn the Rotary
Encoder until the desired parameter group is within the cursor block and press the Rotary Encoder
(repeat if there is a submenu).
Press the Rotary Encoder to select the default setting to be changed and the selection takes on the
reverse video format (dark background, light text). Turn the Rotary Encoder to change the value of the
parameter. Press the Rotary Encoder to accept the new setting or press the Esc key before accepting
the change to exit the menu without saving the change.
For a complete listing of the Program mode menu options, see the section titled Program Mode on pg.
20. Menu items are listed and mapped for convenience. The Direct Access Numbers are listed where
applicable.
The default settings may also be changed by entering the Parameter Number of the setting to be
changed at the Direct Access menu (Program
⇒ Direct Access ⇒ Applicable Parameter Number). A
listing of the Direct Access Numbers and a parameter description of each may be found in the G7 ASD
Operation Manual (P/N 51546).
A listing of all parameters that have been changed from the default setting may be viewed sequentially
by accessing the Changed From Default screen (Program
⇒ Changed From Default).
Note: Parameter F201 was changed to create the example shown in Figure 7.
The Changed From Default feature allows the user to view (or change) the parameters that are
different from the default or the post-reset settings. Once the Changed From Default screen is
displayed, the system automatically scrolls through all of the system parameters and halts oncereaching
a changed parameter.
The Rotary Encoder may be clicked once clockwise to continue scrolling forward or clicked once
counterclockwise to begin scrolling in reverse. With each click of the Rotary Encoder from a stop, the
system scrolls and stops at the next parameter that has been changed.
Pressing the Rotary Encoder while a changed parameter is displayed accesses the settings of the
changed parameter for viewing or changing.
Pressing Escwhile the system is performing a Changed From Default search terminates the search.
Pressing Esc when done searching (or halted at a changed parameter) returns the system to the
Program Menu.

Startup Wizard Requirements
The Startup Wizard queries the user for information on the input and output signal parameters of the
ASD. The drive may also be setup by directly accessing each of the control settings via the Direct
Access Numbers or the Program menu.
Upon initial system powerup, the Startup Wizard starts automatically. The user is queried to either
(1) run the Startup Wizard (Run Now), (2) perform a manual setting of user-selected parameters, or
(3) run the Startup Wizard at the next power up.
If selection (3) is chosen, the system returns to the Program menu and defaults to the Startup Wizard
on the next power up. If selection (2) is chosen, the system returns to the Program menu. If selection
(1) (Run Now) is selected, the Startup Wizard will start and assist the user with the configuration of
the ASD using the following user-input screens:
Voltage and Frequency Rating of the Motor
Motors are designed and manufactured for a specific voltage and
frequency range. The voltage and frequency specifications for a
given motor may be found on the nameplate of the motor.
Upper Limit Frequency
This parameter sets the highest frequency that the ASD will
accept as a frequency command or frequency setpoint. The ASD
may output frequencies higher than the Upper Limit Frequency
(but, lower than the Maximum Frequency) when operating in
the PID Control mode, Torque Control mode, or the Vector
Control modes (sensorless or feedback).
Lower Limit Frequency
This parameter sets the lowest frequency that the ASD will accept
as a frequency command or frequency setpoint. The ASD will
output frequencies lower than the Lower Limit Frequency when
accelerating to the lower limit or decelerating to a stop.
Frequencies below the Lower Limit may be output when
operating in the PID Control mode, Torque Control mode, or the
Vector Control modes (sensorless or feedback).
Adjust Accel/Decel Automatically?
When enabled,the ASDadjusts theaccelerationand deceleration
rates according to the applied load. The acceleration and
deceleration times range from 12.5 to 800% of the programmed
values for the active acceleration time [e.g., Acceleration Time
#1 (F009) and Deceleration Time #1 (F010)].
The motor and the load must be connected prior to selecting
Automatic Accel/Decel. If Automatic Accel/Decel is not enabled, the Acceleration screen will appear
followed by the Deceleration screen.
