G9 ASD Installation and Operation Manual 9
Motor Characteristics
Listed below are some variable speed AC motor-control concepts with which the user of the
ASD should become familiar.
Motor Autotuning
Motor production methods may cause minor differences in motor operation. The negative effects of these
differences may be minimized by using the Autotune feature of the ASD. Autotuning is a function of the
ASD that measures several parameters of the connected motor and places these readings in a stored table.
The software uses the information in the table to help optimize the response of the ASD to applicationspecific load and operational requirements. The Autotuning function may be enabled for automatic
tuning, configured manually at F400, or disabled.
The measured parameters include the rotor resistance, the stator resistance, the required excitation
inductance, rotational inertia values, and leakage inductance values.
Pulse Width Modulation Operation
The ASD uses sinusoidal Pulse Width Modulation (PWM) control. The output current waveform
generated by the ASD approaches that of a perfect sine wave; however, the output waveform is slightly
distorted. For this reason, the motor may produce more heat, noise, and vibration when operated by an
ASD, rather than directly from commercial power.
Low-Speed Operation
Operating a general-purpose motor at lower speeds may cause a decrease in the cooling ability of the
motor. Reducing the torque requirement of the motor at lower speeds will decrease the generated heat at
lower speeds.
When the motor is to be operated at low speed (less than 50% of full speed) and at the rated torque
continuously, a Toshiba VF motor (designed for use in conjunction with an ASD) is recommended.
Overload Protection Adjustment
The ASD software monitors the output current of the system and determines when an overload condition
occurs. The overload current level is a percentage of the rating of the motor. This function protects the
motor from overload.
The default setting for the overload detection circuit is set to the maximum rated current of the ASD at the
factory. This setting will have to be adjusted to match the rating of the motor with which the ASD is to be
used. To change the overload reference level, see Motor Overload Protection Level 1 on pg. 182.
Operation Above 60 Hz
A motor produces more noise and vibration when it is operated at frequencies above 60 Hz. Also, when
operating a motor above 60 Hz, the rated limit of the motor or its bearings may be exceeded; this may void
the motor warranty.
Contact the motor manufacturer for additional information before operating the motor above 60 Hz.
10 G9 ASD Installation and Operation Manual
Power Factor Correction
DO NOT connect a power factor correction capacitor or surge absorber to the output of the ASD.
If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove the
capacitor from the motor.
Connecting either of these devices to the output of the ASD may cause the ASD to malfunction and trip,
or the output device may cause an over-current condition resulting in damage to the device or the ASD.
Light Load Conditions
When a motor is operated under a continuous light load (i.e., at a load of less than 50% of its rated
capacity) or it drives a load which produces a very small amount of inertia, it may become unstable and
produce abnormal vibration or trips because of an over-current condition. In such a case, the carrier
frequency may be lowered to compensate for this undesirable condition (see Program Special
Carrier Frequency PWM Carrier Frequency).
Note: When operating in the Vector Control mode the carrier frequency should be set to
2.2
kHz or above.
Motor/Load Combinations
When the ASD is used in combination with one of the following motors or loads, it may result in unstable
operation.
• A motor with a rated capacity that exceeds the motor capacity recommended for the ASD.
• An explosion-proof motor.
When using the ASD with an explosion-proof motor or other special motor types, lower the carrier
frequency to stabilize the operation. DO NOT set the carrier frequency below 2.2 kHz if operating the
system in the vector control mode.
Note: When operating in the Vector Control mode the carrier frequency should be set to
2.2
kHz or above.
If the motor that is coupled to a load that has a large backlash or a reciprocating load, use one of the
following procedures to stabilize its operation.
• Adjust the S-pattern acceleration/deceleration setting,
• If operating in the Vector control mode, adjust the response time, or
• Switch to the Constant Torque control mode.
G9 ASD Installation and Operation Manual 11
Load-Produced Negative Torque
CAUTION
When the ASD is used with a load that produces negative torque (an overhauling load), the over-voltage
or over-current protective functions of the ASD may cause nuisance tripping.
To minimize the undesirable effects of negative torque the dynamic braking system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking
resistor. The braking resistor must be suitably matched to the load. Dynamic braking is also effective in
reducing the DC bus voltage during a momentary over-voltage condition.
If under extreme conditions the dynamic braking system or a component of this system were to fail, the
dynamic braking resistor may experience an extended over-current condition. The DBR circuit was
designed to dissipate excessive amounts of heat and if the extended over-current condition were allowed
to exceed the circuit parameters, this condition could result in a fire hazard.
To combat this condition, the 3-phase input may be connected using contactors that are configured to open
in the event of an extended DBR over-current condition or an internal circuit failure. Using a thermal
sensor and/or overload protection as the 3-phase input contactor drive signal, the contactors will open and
remove the 3-phase input power in the event of an extended DBR over-current or system over-voltage
condition. See Dynamic Braking on pg. 136 for more information using Dynamic Braking with the ASD.
Motor Braking
The motor may continue to rotate and coast to a stop after being shut off due to the inertia of the load. If an
immediate stop is required, a braking system should be used. The two most common types of motor
braking systems used with the ASD are DC Injection Braking and Dynamic Braking.
For further information on braking systems, see DC Injection Braking on pg. 124 and Dynamic Braking
on pg. 136.
12 G9 ASD Installation and Operation Manual
G9 ASD Characteristics
Over-Current Protection
Each ASD model is designed for a specified operating power range. The ASD will incur a trip if the
design specifications are exceeded.
However, the G9 ASD may be operated at 115% of the specified output-current range continuously (or
110% continuously if 60 HP for the 230-volt system or if 125 HP for the 460-volt system) or at 150%
for a limited amount of time as indicated in the section titled Current/Voltage Specifications on pg. 263.
Also, the Stall Prevention Level may be adjusted to help with nuisance over-current trips (see F601).
When using the ASD for an application to control a motor that is rated significantly less than the
maximum current rating of the ASD, the over-current limit (Thermal Overload Protection) setting will
have to be changed to match the FLA of the motor. For further information on this parameter, see Motor
Overload Protection Level 1 on pg. 182.
ASD Capacity
The ASD must not be used with a motor that has a larger capacity than the ASD, even if the motor is
operated under a small load. An ASD being used in this way will be susceptible to a high-output peak
current which may result in nuisance tripping.
Do not apply a level of input voltage to an ASD that is beyond that which the ASD is rated. The input
voltage may be stepped down when required with the use of a step-down transformer or some other type
of voltage-reduction system.
Using Vector Control
Using Vector Control enables the system to produce very high torque over the entire operating range
even at extremely low speeds. Vector Control may be used with or without feedback. However, using
feedback increases the speed accuracy for applications requiring precise speed control.
See F015 on pg. 81 for further information on using Vector Control.
G9 ASD Installation and Operation Manual 13
Installation and Connections
CAUTION
The G9 True Torque Control2 Adjustable Speed Drive may be set up initially by performing a few
simple configuration settings. To operate properly, the ASD must be securely mounted and connected to
a power source (3-phase AC input at the R/L1, S/L2, and T/L3 terminals). The control terminals of the
ASD may be used by connecting the terminals of the Terminal Board (P/N 072314P903) to the proper
sensors or signal input sources (see the section titled I/O and Control on pg. 21
System performance may be further enhanced by assigning a function to the output terminals of the
Terminal Board and connecting the terminals to the proper indicators or actuators (relays, contactors,
LEDs, etc.).
and
Figure 9 on pg. 24).
Note: Th
e optional ASD interface boards may be used to expand the I/O functionality of the
ASD.
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 be interlocked such that commercial power is
never applied to the output terminals of the ASD (U/T1, V/T2, and W/T3).
DO NOT apply commercial power to the ASD output terminals U/T1, V/T2, and W/T3.
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 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-ap
The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages

avoided.
plication of power via a secondary contact while the G9 ASD is on or while the
motor is still turning may cause ASD damage.
ng the upper or lower-limit settings may require that the over-voltage and under-voltage stall
The frequency of the input power should be ±2 Hz of the specified input frequency.
DO NOT use an ASD with a motor that has a power rating higher than the rated output of the ASD.
The G9 ASD is designed to operate NEMA B motors. Consult with your Toshiba Sales Representative
before using the ASD for special applications such as with an explosion-proof motor or applications
with a piston load.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
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
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.

connecting two or more drives that have no internal fuse to the same power line as shown in Figure 1, 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
— The following thermal specifications apply to the 230- and the 460-volt ASDs ONLY —
Install the unit securely in a well ventilated area that is out of direct sunlight.
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.
The ambient operating temperature rating of the G9 ASD is 14° to 104° F (-10° to 40° C).
When installing adjacent ASDs horizontally Toshiba recommends at least 5 cm of space between
adjacent units. However, horizontally mounted ASDs may be installed side-by-side with no space in
between the adjacent units — side-by-side installations require that the top cover be removed from each
ASD.
For 150 HP ASDs and above, a minimum of 50 cm of space is required above and below adjacent units
and any obstruction.This space is the recommended minimum space requirement for the G9 ASD and
ensures that adequate ventilation is provided for each unit. More space will provide a better
environment for cooling (see the section titled Enclosure Dimensions and Conduit Plate Information on
pg. 254 for additional information on mounting space requirements).
Note: Ensure t
hat the ventilation openings are not obstructed.

Power Connection Requirements
Connect the 3-phase input power to the input terminals of the ASD at R/L1, S/L2, and T/L3 (see
Figure 3 for the typical electrical connection scheme). Connect the output of the ASD to the motor from
the ASD terminals U/T1, V/T2, and W/T3. The input and output conductors and terminal lugs used
shall be in accordance with the requirements listed in the section titled Current/Voltage Specifications
on pg. 263.
If multiple conductors are used in parallel for the input or output power and it is necessary to use
separate conduits, each 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; refer to NEC
Article 300.20 and Article 310.4). National and local electrical codes should be referenced if three or
more power conductors are run in the same conduit (refer to 2008 NEC Article 310 adjustment factors).

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 2008 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.
— 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.
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.
• DO NOT install the input power and output power wires in the same duct or in parallel with each
other, and do not bind them together.
• DO NOT install the input/output power wires 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.
Grounding Capacitor
The Grounding Capacitor plays a role in minimizing the effects of leakage current through the ASD
system and through ground paths to other systems. Leakage current may cause the improper operation
of earth-leakage current breakers, leakage-current relays, ground relays, fire alarms, and other sensors
— and it may cause superimposed noise on CRT screens.
The Grounding Capacitor Switch allows the user to quickly change the value of the leakage-reduction
capacitance of the 3-phase input circuit. See figures 4, 5, 6, and 7 on pg. 19 for an electrical depiction of
the leakage-reduction functionality and the methods used to change the capacitance value. The method
used is typeform-specific.
If using a 460-volt 5 HP ASD or a 460-volt ASD that is in the range of 7.5 HP to 25 HP, and the U/T1,
V/T2, and W/T3 connections to the motor are 100 meters or more in length, the ASD Carrier
Frequency must be set to 4 kHz or less when activating or deactivating the Grounding Capacitor
Switch. ASD overheating may occur if the Carrier Frequency is set above 4 kHz when activating or
deactivating the Grounding Capacitor Switch.
See pg. 5 for more information on the Grounding Capacitor Switch and pg. 16 for the location of the
switch.
