6 Q7 ASD Installation and Operation Manual

Personnel Protection

• Instal lation, operation, and maintenance shall be performed by Qualified Personnel Only.

• A thorough understanding of the ASD will be required before the installation, operation, or
maintenance of the ASD.

WARNING

• Rotating machinery and live conductors can be hazardous and s hall not come into contact with
humans. Personnel should be protected from all rotating machinery and electrical hazards at all
times.

• Insulat ors , machine guards, and elect rical safeguards may fail or be defea ted by the purposeful or
inadvertent actions of workers. Insulators, machine guards, and electrical safeguards are to be
inspected (and tested where possible) at installation and periodically after installation for potential
hazardous conditions.

• Do not allow personnel near rotating machinery. Warning signs to this effect shall be posted at or
near the machinery.

• Do not all ow pe rsonne l near e lectr ical conduc tors. Human cont act wi th e lect rical conduct ors c an be
fatal. Warning signs to this effect s hall be posted at or near the haza r d.

• Personal protection equipment shall be provided and used to protect employees from any hazards
inherent to system operation.

• Follow all warnings and precautions and do not exceed equipment ratings.

System Setup Requirements

• When using the ASD as an integral part of a larger syste m, it is the responsibi lity of the ASD
installer or maintenanc e p er sonnel to en sure tha t th ere is a fai l-safe in place, i.e., an arr an gement
designed to switch the system to a safe condition if there is a fault or fail ure.

• System safety features should be empl oyed and designed into the integrated system in a manner
such that s ys te m op e r at io n , ev en in th e ev e nt of sy s te m fa i lu r e, wi ll no t cau s e h arm o r res ul t in
personnel injury or system damage (i.e., E-Off, Auto-Restart settings, System Inte rlocks, etc.).

• The programming s etup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Auto-restart settings is a requi rem ent to use this product.

• Improperl y desig ned or impr operly inst al led syst em interl ocks may ren der the m otor unabl e to star t
or stop on command.

• The failure of external or ancillary components may cause intermittent system operation, i.e., the
system may sta rt the motor without warning.

• There may be thermal or physical properties, or ancillary devices integrated into the overall sy stem
that may allow for the ASD to start the motor without warning. Signs at the equipment installation
must be posted to this effect.

• If a secondary magnetic contactor (MC) is use d between the ASD and the load, it should be
interlocke d to halt the ASD before the secondary contact opens. If the output contactor is used for
bypass operati on, it must be interlocked such that commercial power is never appl ied to the ASD
output terminals (U, V, W).

• Power factor improvement capacitors or surge absorbers must not be installed on the output of the
ASD.

Q7 ASD Installation and Operation Manual 7

• Use of the built-in system protective fea tures is highly recommended (i.e., E-Off, Overload
Protection, etc.).

• The operating controls and system sta tus indicators should be cl ea rly readable and positioned
where the operator can se e the m wit hout obstruction.

Q7 ASD Installation and Operation Manual 11

Motor Characteristics

Listed below are some va riable speed AC motor control concepts with which the user of the
Q7 Adjustable Speed Drive should become familiar.

Pulse Width Modula tio n Op e ration

The Q7 ASD uses a sinusoidal Pulse Width Modulation (PWM) contr o l system. The output current
waveform generated by the ASD approaches that of a perfect sine wave; however, the output waveform
is slightly dis torted. For this reason, the motor may produce more heat, noise, and vibration when
operated by an ASD, rather than directly from commercial power.

Overload Protection Adjustment

The Q7 ASD software 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 detect ion circuit is set to the maximum ra ted current of the ASD at
the factor y. This sett ing will have to be adj usted to matc h the rating of the motor with which the ASD is
to be used. To change the overload reference level, see

(Electronic) Thermal Protection #1 on pg. 62.

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 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-current 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 produce s a very small amou nt 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 Parameters

Note: For proper operation, the carrier frequency must be 2.2 kHz or above except whe n

operating in the Constant Torque or Variable Torque modes.

⇒

PWM Carrier Frequency).

Load-pro du ce d Nega tiv e Torque

When the ASD is used wi th a loa d that pro duc es negat ive torq ue (an ove rhauli ng loa d), the over -vol ta ge
or over-current protective functions of the ASD may cause nuisance tripping.

⇒

Special

To minimize the undesi rable effects of negative torque the dynami c braking system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking

12 Q7 ASD Installation and Operation Manual

resistor. The braking resistor must be s uitably matched to the load. Dynami c 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 co ndition. 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 interna l circuit failure. Usi ng 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-phase input power in the event of an extende d DBR over-c urrent or syst em over­voltage condition.

Motor Braking

The motor ma y 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 shoul d be us ed. The two most common types of motor
braking system s use d with the Q7 ASD are DC Injection Braking and Dynamic Braking.

For further information on braking systems, see DC Injection Braking Current on pg. 57 and

Dynamic Braking Enable on pg. 60.

CAUTION

ASD Characteristics

Over- current Protection

Each Q7 ASD model was designed for a speci f ied operating power range. The 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
110% for a limited time as indicated in the section titled
Also, the Overcurren t Stall Level setting m ay be adjusted to help with nuis ance over-curre nt trips.

When using the ASD for an a pplication that controls a motor which is r ated signifi cantly less than the
maximum current rating of the ASD, the over-c urrent limit (Thermal Overload Protection) setting will
have to be changed to match the application. For further i n fo r mation on this paramete r, see

Thermal Prote ction #1 on pg. 62.

ASD Capacity

The Q7 ASD must not be used with a mot or that has a significantly larger capacity, 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 trippin g.

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 some other type of
voltage-reduction system.

Current/Voltage Specif ications on pg. 162.

Q7 ASD Installation and Operation Manual 13

Installation and Connections

The Q7 Adjustable Speed Drive may be set up initially by performing a few simple configura tion
settings. To operate properly, the ASD must be securely mounted and connected to a power source (3­phase AC input at th e 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 T erminal Strip to the proper sensors or si gnal inpu t source s
(see the section titled

The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor th at is to be
controlled (see

As a minimum, the installation of the ASD shall conform to Article 110 of the 2005 NEC, the
Occupational Safety and Health Administration requirements, and to any other local and regional
industry code s a nd st andards.

Installation Notes

When a brake-equipped motor i s connected to th e ASD, it is po ssible that the brak e may not rele ase 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 between the output o f the ASD and the motor, it should
be interlocked such that the ST – CC connection is disconnected before the output contac tor is opened.

I/O and Control on pg. 19).

Figure 18 on pg. 26).

Do Not open and then close a secondary magnetic c ontactor betwee n the ASD and the motor unless the
ASD is off and the motor is not rotating.

Note: Re-applicat ion of power via a secondary contact while the ASD is on or while the

motor is s t il l turni n g m a y ca u s e ASD dam a g e.

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)
only after norma l system pow er 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 th e
ASD is running. For the 230 volt ASD this feature is available on the 40 HP and above systems, on the
460 volt ASD this featu re is ava ilable on the 75 HP and above systems , and on the 600 volt ASD it is
available on the 60 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 voltage ra nge. Input voltages
approaching the upper or lower limit setti ngs may require that the overvoltage and undervolta ge 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 rate d output of the ASD.

14 Q7 ASD Installation and Operation Manual

The ASD is designed to operate NEMA B motors. Consult with your sales repr es entative before using

Figure 3. Circuit breaker configuration.

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 bypass voltage to the motor.
Interface problems may occur when an ASD is used in conjunction with some types of process

controllers. Signal isolation ma y be req uired to prevent controll er 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 da ma ge to the motor and/or the driven equipment.

All Q7 AS Ds are equipped with inte rnal DC bus fuses. However, not all Q7 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 3, it will be necessary to selec t a ci rcuit-

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 conf iguration, inse rt a fuse between MCCB2 and ASD 1 (repeat
for successive ASDs).

Q7 ASD Installation and Operation Manual 15

Mounting the ASD

CAUTION

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 Q7 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 dissipa ted as heat. If installing the AS D i n a cabinet, ensure that
there is adequate ventilation.

Do Not operate the ASD with the enclosure door open or removed.
When ins t alling m ultiple ASDs , ensure th at there is a clearance space of at least 8 inches (20 cm ) from

the top and the bottom of adjacent units. Th ere should be at least 2 inches (5 cm) on either side of
adjacent un its. For the models below 50 HP the top and bot tom clea rance spe cific ations may be reduc ed
to 4 inch es (10 cm ) . Thi s sp ace ensur es th a t ad eq u ate vent ilation is p r ov i d ed (see the se ct io n ti tl e d

Enclosure Dimensions and Conduit Plate Information on pg. 152 for additional information on

mounting space requirements).

Note: Ensure that the ventilation openings are not obstructed.

ASDs produce high-frequency noise — steps must be taken during installa tion 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 th e sam e duct or in parallel with each other, and do not bind them together .

• 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, and 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.

• Connect a surge suppressor to every electromagnetic contactor and every relay installed near the

ASD.

• Install noise filters as required.

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 termin a ls.

T1/U, T2/V, and T3/W are the output terminals of the ASD that connect to the motor.
An inductor may be connecte d ac ross terminals PA and PO to provide additional filtering. When not

used, a jumper is connected across these terminals (see
Connect the inpu t and output power lines of the ASD as shown in Figure 4.

Note: In the event that the motor rotates in the wrong direction when pow ered up, reverse

any two of the three A SD output power leads connected to the motor.

Q7 ASD Control

r.

l

The Control PCB (P/N 56000) serves as the primary control source for the Q7 ASD and receives input
from the

Keypad.

The Control PCB has been enhanced to support two new functions: Multiple Protocol Commun ications
and the ability to communicate in either half- or f u ll-duplex mode s.

Using the optional multiple-protocol communications interface: the ASD-NANOCOM, the Control
PCB may be configured for the type of co mmunications protocol being received and respond
appropriate ly to the sending device. The ASD-NANOCOM connect s to the J4 and J5 connectors
(see Figure 7). A jumper PCB (P/N 55365) is required at the J4 connector if not using the ASD­NANOCOM.

Control Terminal Strip PCB, an Option Card, RS232/485 Communic ations, or the Q7 ASD

The ASD-NANOCOM must be setup to support the des ired communications protocol via Program
Com m Settings . Consult the ASD-NANOCOM User’s Manual (P/N 10572-1.000-000) for a complete
listing of the setup requirements.

Half or Full duplex communica tions is available when using RS232/485 communications. The jum pers
at the JP1 and the JP2 connectors may be moved from one position to the other to facilitate either half­or full-duplex operation. If no jumpers are used the system will operate in the full duplex mode.

For more information on the Q7 ASD communication requirement s , please visit
