When not used for long periods,
charge semi-annually.
Listed below are some va riable speed AC motor contro l conc epts with which the user of the
W7 Adjustable Speed Drive should become familiar.
Pulse Width Modula tio n Op e ration
The W7 ASD uses a sinusoidal Pulse Width Modulation (PWM) control system. The output current
waveform generated by the ASD approaches that of a perfect sin e wa ve; however, the output waveform
is slightly dis torted. For this reason, the motor may produce more heat, nois e, and vibration when
operated by an ASD, rather than directly from commercial power.
Overload Protecti on Adjustment
The W7 ASD sof tware monitors the output current of the system and determines when an overload
condition occ urs . 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 factor y. This sett ing will have to be adjusted to m atch the rat ing of the motor with which the ASD is
to be used. To change the overload re ference level, see
Electro nic Thermal Protection #1 on pg. 70.
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 fro m the motor.
Connecting e ither of t hese device s to the out put of the ASD may c ause the ASD to mal func tion an d tri p,
or the output device may cause an over-c urrent condition resu lting 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
Control
Note:For proper operation, the carrier fre quency must be 2.2 kHz or above except when

To minimize the undesirable effec ts of nega tive torque the dynami c bra king system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking
W7 ASD Installation and Operation Manual11
resistor. The braking resistor must be s uitably matched to the load. Dyna mi c braking is also e ffective in
reducing the DC bus voltage during a momentary over-voltage condition.
If under extreme conditions t he dynamic braking s ys tem or a component of this system were to fail, the
dynamic braking resistor may experience an exte nded over-current condition. The DBR circuit was
designed to di ssi pate excessive amou nts of heat and if t he extend ed over -curre nt condit ion were al lowed
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 int ernal circuit failure. Using a
thermal sen sor an d/or overloa d pro tect ion as th e 3- phase input c ont actor driv e sig nal, t he con tact ors wil l
open and remove the 3-phas e input power in the event of an ext ended DBR over -current or sys tem overvoltage condition.
Motor Braking
The motor ma y continue to rotate an d coast to a stop after being shut off due to the in ertia of the load. If
an immediate stop is required, a braking system should be used. The two most common types of motor
braking system s use d with the W7 ASD are DC Inject ion Bra k ing and Dynamic Braking.
For further information on braking systems, see DC Injection Braki n g Current on pg. 65 and
Dynamic Braking Enable on pg. 68.
CAUTION
ASD Characteristics
Over- current Protection
Each W7 ASD model was designed for a specified operating powe r range . T he ASD will incur a trip if
the design specifications are exceeded.
However, the ASD may be operated at 100% of the specified output-current range continuously or at
120% for a limited time as ind icated in the section titled
Also, the Overcurren t Stall Le ve l setting may be adjus ted to help with nuisance over-current trips.
When using the ASD for an a pplication tha t controls a motor which is r ated significantly less than the
maximum current rating of the ASD, the over-c urrent limit (Thermal Overload Protectio n) setting will
have to be changed to match the application. For further information on this parameter, see
Thermal Protection #1 on pg. 70.
ASD Capacity
The W7 ASD must not be used with a motor that has a significantly larger ca pacity, even i f 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 if require d with the use of a step-down transformer or som e other type of
voltage-reduction system.

12W7 ASD Installation and Operation Manua l
Installation and Connections
The W7 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 (3phase AC input at the L1/R, L2/S, and L3/T terminals). The control terminals of the ASD may be used
by connecting th e termi nals of the Control Terminal Strip to the proper sensors or signal input sou rces
(see the section titled
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
As a minimum, the installation of the ASD shall conform to Article 110 of the 2005 NEC, the
Occupational SafetyandHealth Administration requirements, and to any other loca l and regional
industry code s a nd st andards.
Installation Notes
When a brake-equipped motor is connected to the ASD, i t is possible that the b r ake may not release at
startup be cause of i nsuf f icie nt vo ltage . To avoid this, Do Not conn ect t h e b rake or t he b ra ke cont ac to r to
the output of the ASD.
If an output cont actor i s used for byp ass opera tion, it mus t be int erlock ed such tha t commer cial po wer is
never applied to the output terminals of the ASD (T1/U, T2/V, or T3/W).
If a secondary magnetic contact or (MC ) is used betwe en the output o f the ASD and the motor, it should
be interlocked such that the ST – CC connection is disconnected before the output cont actor is opened.
I/O and Control on pg. 17).
Figure 17 on pg. 24).
Do Not open and then close a secondary magneti c contactor bet w een the ASD and the m otor unless the
ASD is off and the motor is not rotating.
Note:Re-applicat ion of power via a secondar y contact while the ASD is on or while the
motor is s t il l turnin g m ay cause ASD dam a g e.
On some devices the ST-to-CC connection is further enhanced by the operat ion of the MS1 AUX relay
circuit. The MS 1 AUX relay circuit is normally open and closes the ST-to-CC connection (via ST1)
only after normal system p o w er is available. Th e 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. For the 460 volt ASD this feature is availab le on the 75 HP and above systems.
Figure 2. Alternative ST activation using the MS1 AUX circuit configuration.
The ASD input voltage should remain within 10% of the spec ified input volta ge range. Input voltages
approaching the upper or lower limit settings may require that the overvoltage and undervo ltage stall
protection level parameters be adjusted. Voltages outside of the permissible tolerance should be
avoided.
The frequency of the inp ut power should be ±2 Hz of the specified input frequency.
Do not use an ASD with a motor t hat has a power rating that is higher than the rated output of the ASD.
W7 ASD Installation and Operation Manual13
The ASD is designed to operate NEMA B motors. Consult with your sales representative before using
CAUTION
the ASD for special applica tions 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 bypa s s voltage to the motor.
Interface problems may occur when an ASD is used in conjunction with some types of process
controllers. Signal isolati on ma y be req uired to prevent controll er and/or ASD malfunction (c ontact
your Toshiba sales repre s entative or the process controller manufacturer for additional informat ion
about compatibility and signal isolation).
Use caution when setting the output fre quency . Over speeding a motor decreases its abilit y to deliver
torque and may result in da ma ge to the motor and/or the driven equipment.
All W7 ASDs are equipped with internal DC bus fuses. However, not all W7 ASDs are equip ped wit h
internal primary power input fuses (HP-dependent).
Mounting the ASD
Install the unit securely in a well ventilated area that is out of direct sunlight using the mounting holes
on the rear of the ASD.
The ambient temperature rating for the W7 ASD 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 inp u t energy to the ASD may be dissipated as heat. If installing t h e A SD in a cabinet, ensur e that
there is adequate ventilation.
Do Not operate the ASD with the enclosure door open or removed.
Note:Ensure that the ventilation ope nings are not obstructed.
ASDs produce high-frequency noise — steps must be ta ken 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 instal l the input and
output wires in th e sam e duct or in parallel with each other, and do not bind them to gether.
•Do not insta ll the input or output powe r conductors of the main circuit and the wires of the control
circuit in the sa me duct or in parallel with each other, a nd do not bind them together.
•Use shielded wires or twis te d wires for the control circuits.
•Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.
14W7 ASD Installation and Operation Manua l
•Connect a surge suppressor to every electromagnetic contactor and every relay installed nea r the
ASD.
•Install noise f ilters as required.
