6.0 THEORY

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

6.1 DESCRIPTION OF AC MOT OR OPERATION

Three phase AC motors are comprised of two major components, the stator and th e rotor. The stator is a
set of three electrical windings held stationar y in the motor housing. The rotor is a metal cylinder, fixed
to the motor drive shaft, which rotates within the stator. The ar rangemen t of the stator coils and the
presence of three phase AC voltage give rise to a rotating magnetic field which drives the rotor. The
speed at which the magnetic field rotates is known as the synchronous speed of the motor. Syn chronous
speed is a function of th e fr equency at which the voltage is alternating and the number of poles in the
stator windings.

The following equation gives the relation between synchronous speed, frequency, and the number of
poles:

Ss = 120 f/p

Wher e: Ss = Syn chr onous speed (rpm ), f = frequency (Hz), p = nu mber of poles

In three phase induction motors the actual shaft speed differs from the synchronous speed as load is
applied. This difference is known as "slip". Slip is commonly expressed as a percentage of synchronous
speed. A typical value is three percent at full load.

The strength of the magnetic field in the gap between the r otor and stator is proportional to the amplitude
of the voltage at a given frequency. The output torque capability of the motor is, therefore, a function of
the applied voltage amplitude at a given frequency. When operated below base (rated) speed, AC motors
run in the range of "constant torque". Constant torque output is obtain ed by maintaining a constant ratio
between voltage amplitude (volts) and frequency (Hz). For 60 Hz, 230, 460, and 575 volt motors,
common values for this V/Hz ratio are 3.83, 7.66, and 9.58 respectively. Operating with these V/Hz
ratios gen erally yield optimum torque capability. Operating at lower ratios decreases tor que an d power
capability. Operating at higher ratios will cause the motor to overheat. Most standard motors are capable
of providing full torque output from 3 to 60 Hz. However , at lower speeds, where motor coolin g fan s
becom e less effective, supplemental cooling may be n eeded to operate at full torque output continuously.

If the fr equency applied to the motor is increased while the voltage remains constant, torque capability
will decrease as speed increases. This will cause the horsepower capability of the motor to remain
app roxi mate ly const ant . Motor s ru n in thi s mode wh en op erat ed above ba se speed , wher e dr ive out put
voltage is limited by the in put line voltage. This operating range is known as the "constant horsepower"
range. The typical maximum range for constant horsepower is about 2.3 to 1 (60 to 140 Hz). The
diagram below depicts the operating characteristics of a typical AC induction motor .

6.1.1 CONSTANT T ORQUE VS. VARIABLE TORQUE

Variable frequency dri ves, an d the loads they a re applied to, can generally be divided into two groups:
constant torque and variable torque. Constant torque loads include: vibrating conveyors, punch presses,
rock crushers, machine tools, and just about every other application that is not considered variable torque.
Variable torque loads include centrifugal pumps and fans, which make up the majority of HVAC
applications.

The term constant torque is not entirely accurate in terms of the torque required for an application.
Many constant torque applications have reciprocating loads, such as vibrating conveyors and punch
presses, wh ere the rotation al motion of the motor is being converted to a lin ear motion. In such cases, the
torque required can vary greatly at different poin ts in the cycle. For constant torque loads, this flucuation
in torque is not a dir ect function of speed, as it is with a variable torque load.

TORQUE

Variable torque loads are governed by the affinity laws, which define the relationships between speed,
flow, torque and horsepower. The diagram below illustrates these relation ships:

Variable torque refers to th e fact that the torque requir ed varies with the square of the speed. Also, the

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

horsepower required varies with the cube of the speed, resulting in a large reduction in horsepower for
even a small reduction in speed. It is easily seen that substantial energy savings can be achieved by
reducing the speed of a fan or pump. For example, reducing the speed to 50% results in a 50 HP motor
having to produce only 12.5% of rated horsepower, or 6.25 HP.

There are two major differences between a constant torque drive and a variable torque drive. One is that a
constant torque drive generally has a higher overload capacity rating. Constant torque loads have higher
peak torque demands, which require the ability to handle higher currents. Variable torque loads rarely
experience full load, and therefore usually have a lower overload capacity. The other difference is that
constant torque drives follow a constant V/Hz ratio to achieve maximum torque, while variable torque
drives follow a variable V/Hz ratio to optimize efficiency and energy savings.

6.2 DRIVE FUNCTION DESCRIPTION

The QC Series is a 16 bit microprocessor based, keypad programmable, variable speed AC motor drive.
There are four major sections; an input diode bridge and DC bus filter, a power board, a control board, and
an output intelligent power module.

6.2.1 DRIVE OPERATION

Incoming AC line voltage is converted to a pulsating DC voltage by the input diode bridge. The DC
voltage is supplied to the bus filter capacitors through a charge circuit which limits inrush current to the
capacitors during power-u p. The pulsating DC voltage is filter ed by the bus capacitors which re duces the
ripple level. The filtered DC voltage enters the inverter section of the drive, composed of six output
intelligent insulated gate bi-polar transistors (IGBT’s) which make up the three output legs of the drive.
Each leg has one intelligent IGBT connected to the positive bus voltage and one connected to the negative
bus voltage. Alternately switching on each leg, the intelligent IGBT produces an alternating voltage on
each of the corresponding motor windings. By switching each output intelligent IGBT at a very high
frequency (known as the carrier frequency) for varying time intervals, the inverter is able to produce a
smooth, three phase, sinusoidal output current wave which optimizes motor performance.

6.2.2 CIRCUIT DESCRIPTION

The control section consists of a control board with a 16 bit microprocessor, keypad and display. Drive
programming is accomplished via the keypad or the serial communications port. During operation the
drive can be controlled via the keypad, by control devices wired to the control terminal strip, or by the
serial communications port. The Power Board contains the control and protection circuits which govern
the six output IGBT’s. The Power Board also co ntains a charging circuit f or the bus filter capacitors, a
motor current feedback circuit, a voltage feedback circuit, and a fault signal circuit. The drive has several
built in protection circuits. These include phase-to-phase and phase-to-ground short circuit protection,
high and low line voltage protection, protection against excessive ambient temperature, and protection
against continuous excessive output current. Activation of any of these circuits will cause the drive to shut
down in a fault condition.

6.2.3 QC ANALOG INPUT SIGNALS

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

The QC Series drive allows for three speed reference input signals: speed potentiometer (10,000 Ohm), 4­20 mA, or 0-10 VDC. For control by a speed pot., th e wiper lead is connected to terminal TB-5A, and the
hig h an d low end l eads ar e connected to termi nals TB-6 an d TB-2, r espectivel y. For 4-20 mA con trol,
wire the positive to terminal TB-5B and the negative to terminal TB-2. For 0-10 VDC control, wire the
positive to terminal TB-5D and the negative to terminal TB-2. See the control wir ing diagram in Section

15.0.

The input im pedance of termina l TB-5A (speed pot input) is 100 kilohms, TB-5B (4-20 m A input) is
100 ohms, and TB-5D (0-10 VDC input) is 200 kil ohm s. T erm i nal TB-2 is circuit common.

The control voltage of the microprocessor control board is 24 VDC, (Isolated, referenced to circuit
common - terminal TB-2).

6.2.4 QC ANALOG OUTPUT SIGNALS

There are four terminals that can supply a nalog output signals proportional to output frequency or load.
Terminal TB-10B can provide a 0-10 VDC signal proportiona l to frequency or load. Termi nal TB-10C
provides a 12 VDC pulse train proportional to frequency with a 40-50% duty cycle. Term inal TB-10D
can provide a 4-20 mA signal pr oportional to frequency or load, and termin al TB-10E can provide a 0-10
VDC or 2-10 VDC sign al proportional t o frequency or l oad. The 2-10 VDC signal can be converted to a
4-20 mA signal usin g a resistor in ser ies with the signal such that t he total circuit resistan ce is 500 ohm.
See Parameters: 50 - TB10B/D FUNCTION, and 53 - TB10E FUNCTION in Section 18.0 ­DESCRIPTION OF PARAMETERS.

6.2.5 QC ST AT US OUTPUT RELAYS

The control board has two FORM C relays at terminals TB-16, 17, 18, and TB-19, 20, 21. TB-16 and
TB-19 are normally open contacts, and TB-18 and TB-21 are normally closed contacts. TB-17 and TB-20
are common. Contacts are ra ted 2 amps at 28 VDC or 120 Vac.

Ther e i s a l so one op en -col lect or out put a t t er m inal T B-1 4. T h e open -col lect or cir cu it is a cur ren t- si n ki n g
type rated at 30 VDC and 40 mA maximum.

The FORM C relays and the open-collector output can be pr ogrammed to indicate any of the following:
NO FUNCTION, RUN, FAULT, FAULT LOCKOUT, AT SPEED, ABOVE SET SPEED, CURRENT
LIMIT, FOLLOWER PRESENT, MAINTENANCE TARGET, AUTO SPEED MODE, or START
PENDING. See Parameters: 121 - RELAY #1 FUNCTION, 122 - RELAY #2 FUNCTION, and 124 - TB­14 FUNCTION, in Section 18.0 - DESCRIPTION OF PARAMETERS.

The following describes the functionality of the possible relay output settings:

NO FUNCTION This setting disables the relay output.

RUN The relay energizes when the drive is given a START command, and remains

energized until: a STOP command is given and the output frequency has
deceler ated to 0. 5 Hz, th e dri ve has "t ri pped", or th e in put volt age is removed.
Note that this relay indicates only that the drive is in the RUN mode. It does
not necessarily indicate that the motor is turnin g.

18

FAULT The relay energizes when input voltage is applied to the drive and remains

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

energized until the drive “trips” into a fault condition, or input voltage is
removed.

FAULT LOCKOUT This relay can be used when the drive is programmed to automatically restart

after a fault. The relay energizes when input voltage is applied to the drive and
remains energized until the drive has faulted and unsuccessfully attempted the
number of restarts programmed in Parameter 72 - RESTART LIMIT, or input
voltage is removed.

AT SPEED The relay energizes when the drive reaches the commanded frequency. To avoid

a “chattering” relay (constantly energizing and de-energizing) due to small
fluctuations in speed, the relay will change states only when the speed has
changed by +

ABOVE SET SPD ABOVE SET SPEED - The relay energizes when the output frequency of the

drive exceeds the value in Parameter 123 – REL. SET SPD, and de-energizes
when the output frequency is equal to or less than REL. SET SPD.

CURRENT LIMIT The relay energizes when the drive is operating in current limit. Once the current

limit relay is energized, it remains energized for a minimum of 500ms, regardless
of whether the drive is still in current limit. At the end of the 500ms interval, the
relay will de-energize if the drive is no longer in current limit. See Parameter 1 ­CURRENT in Section 18.0 - DESCRIPTION OF PARAMETERS.

FOLLOWER PRES FOLLOWER PRESENT - The relay energizes when the 4-20 mA speed

reference input signal (TB-5B) is greater than 2 mA, and de-energizes when the
signal falls below 2 mA.

MAINT. TARGET MAINTENANCE TARGET - The relay energizes after the time period

programmed in Parameter 132 - MAINTENANCE TARGET has elapsed. The
relay will de-energize when a new time is programmed into Parameter 132.

AUTO SPEED MODE The relay energizes when the drive is in the AUTOMATIC MODE, and de-

energizes in the MANUAL MODE. This function is active only if Parameter 67

- AUTO/MANUAL SELECT is set to AUTO/MANUAL SPEED or
AUTO/MANUAL LOCAL. The relay will remain energized if Parameter 67 is
set to AUTO SPEED. This function will not be active if Parameter 67 is set to
MANUAL SPEED.

START PENDING The relay will energize if the drive has faulted, and is programmed for automatic

restart after a fault. START PENDING will appear on the keypad display when
the drive is in this condition. The relay will de-energize after the delay
programmed into Parameter 73 - RESTART DELAY, at which time the drive
will attempt to restart.

7.0 INSTALLATION

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

DRIVES MUST NOT BE INSTALLED WHERE SUBJECTED TO ADVERSE ENVIRONMENTAL
CONDITIONS! DRIVES MUST NOT BE INSTALLED WHERE SUBJECTED TO: COMBUSTIBLE,
OILY, OR HAZARDOUS VAPORS OR DUST; EXCESSIVE MOISTURE OR DIRT; STRONG
VIBRATION; EXCESSIVE AMBIENT TEMPERATURES. CONSULT AC TECHNOLOGY FOR
MORE INFORMATION ON THE SUITABILITY OF A DRIVE TO A PARTICULAR ENVIRONMENT.

The drive should be mounted on a smooth vertical surface capable of safely supporting the unit without
vibrating. The LCD display has an optimum field of view, this should be considered when determining the
mounting position.

Chassis models must be installed in an electrical enclosure which will provide complete mechanical
protection and maintain uniform internal temperature within the drive’s ambient operating temperature
rating. All drive models MUST be mounted in a vertical position for proper heatsink cooling.

Maintain a minimum spacing around the drive of 4 inches for units rated 20 HP and below, 6 inches for
units rated 25-50 HP, and 8 inches for units rated 60 HP and above.

Fans or blowers should be used to insure proper cooling in tight quarters. Do not mount drives above other
drives or heat producing equipment that would impede the cooling of the drive. Note the ambient
operating temperature ratings for each drive model.

WARNING!

If it is necessary to drill or cu t the drive en closure or p anel, extreme care must be take n to avoid da maging
drive components or contaminating the drive with metal fragments (which cause shorting of electrical
circuits). Cover drive components with a clean cloth to keep out metal chips and other debris. Use a
vacuum cleaner to clean drive components after drilling, even if chips do not appear to be present. Do not
attempt to use positive air pressure to blow chips out of drive, as this tends to lodge debris under electronic
components. Contaminating the drive with metal chips can cause drive failure and will void the warranty.

7.1 INSTALLATION AFTER A LONG PERIOD OF STORAGE

WARNING!

Severe damage to the drive can result if it is operated after a long period of storage or inactivity without
reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding one year (due to storage,
etc), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive
leakage current. This can result in premature failure of the capacitors if the drive is operated after such a
long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply
input power to the drive for 2 hours prior to actually operating the drive/motor system.

8.0 INPUT AC POWER REQUIREMENTS

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

W ARNING!

Hazard of electrical shock! Disconnect incoming power and wait three minutes before servicing the drive.
Capacitors retain charge after power is removed.

8.1 INPUT AC POWER REQUIREMENTS

8.1.1 VOLTAGE:

The system line voltage must match the drive’s input voltage rating. Voltage fluctuation must not vary by
greater than 10% overvoltage or 15% undervoltage.

NOTE: Drives with dual rated input voltage must be programmed for the proper supply voltage - see Parameter
94 - AC INPUT in Section 18.0 - DESCRIPTION OF PARAMETERS SECTION.

The drive is suitable for use on a circuit capable of delivering not more than 200,000 RMS symmetrical
amperes, at the drive’s rated voltage.

Three phase voltage imbalance must be less than 2.0% phase to phase. Excessive phase to phase imbalance
can cause severe damage to the drive’s power components.

Motor voltage should match line voltage in normal applications. The drive’s maximum output voltage will
equal the input voltage. Use extreme caution when using a motor with a voltage rating which is different from
the input line voltage.

8.1.2 kVA RATINGS:

If the kVA rating of the AC supply transformer is greater than ten times the input kVA rating of the drive, a
drive isolation transformer, or a 2 - 3% input line reactor (also known as a choke) must be added. This only
applies to 240/200 Vac and 480/400 Vac models rated 20 HP and below, and 590/480 Vac models rated 3 HP
and below, as larger units have standard built-in line reactors.

8.2 INPUT FUSING AND DISCONNECT REQUIREMENTS

A circuit breaker or a disconnect switch with fuses must be provided in accordance with the National Electric
Code (NEC) and all local codes.

The QC1000 and QC2000 drives are capable of withstanding up to 150% current overload for 60 seconds,
and the QC3000 is capable of 120% current overload for 60 seconds. Therefore, select a fuse or magnetic trip
circuit breaker rated at a maximum of 1.5 (QC1000/2000), or 1.25 (QC3000) times the input current rating of
the drive. Refer to Section 5.0 - DRIVE RATINGS.

Minimum voltage rating of the protection device should be: 250 Vac for 240/120 Vac and 240/200 Vac rated
drives, and 600 Vac for 480/400 Vac and 590/480 Vac drives.

If using fuses, current limiting fuses should be used. Select fuses with low I
Recommended fuses are Bussman type KTK-R and JJN for 240/200 Vac models, or type KTK-R and JJS for
480/400 Vac and 590/480 Vac models. Similar fuses with equivalent ratings by other manufacturers may
also be acceptable.

Hazard of electrical shock! Disconnect incoming power and wait three minutes before servicing the drive.
Capacitors retain charge after power is removed.

Note drive input and output current ratings and check applicable electrical codes for required wire type and
size, grounding requirements, over-current protection, and incoming power disconnect, before wiring the
drive. Size conservatively to minimize the voltage drop.

Input fusing and a power disconnect switch or contactor MUST be wired in series with terminals L1, L2, and
L3 (L1 and L2 if input is single phase). If one has not been supplied by AC Technology Corporation, a
disconnect means must be wired during installation. This disconnect must be used to power down the drive
when servicing, or when the drive is not to be operated for a long period of time, but should not be used to start
and stop the motor. Repetitive cycling of a disconnect or input contactor (more than once every two minutes)
may cause damage to the drive.

10.1 WIRING FOR SINGLE PHASE OR THREE PHASE INPUT

If the drive is nameplated for single phase input only, wire input to terminals L1 and L2.

If the drive is nameplated for single or three phase input, wire input to terminals L1 and L2, and jump L2 to L3
for single phase input, or wire input to L1, L2, and L3 for three phase input.

If the drive is nameplated for three phase input only, wire input to terminals L1, L2, and L3.

All three power output wires, from terminals T1, T2, and T3 to the motor, must be kept tightly bundled and
run in a separate conduit away from all other wiring.

It is not recommended to install contactors or disconnect switches between the drive and motor. Operating
such devices while the drive is running can potentially cause damage to the drive's power components. If
such a device is required, it should only be operated when the drive is in a STOP state. If there is potential for
the device to be opened while the drive is running, the drive must be programmed for COAST TO STOP (see
Parameter 65 - COAST STOP), and an auxiliary contact on the device must be interlocked with the drive's run
circuit. This will give the drive a stop command at the same time the device opens, and will not allow the
drive to start again until the devide is closed.

INSTALL, WIRE, AND GROUND IN ACCORDANCE WITH ALL APPLICABLE CODES.

NOTES:

1. Wire the motor for the proper voltage per the output rating of the drive. Motor wires MUST be run in a
separate steel conduit away from control wiring and incoming AC power wiring.

2. Do not install contactors between the drive and the motor without consulting AC Technology for more
information. Failure to do so may result in drive dam a ge.

3. Remove any existing, and do not install, power factor correction capacitors between the drive and the
motor. Failure to do so will re sult in drive damage.

4. Use only UL and CSA listed and approved wire.

5. Minimum wire voltage ratings: 300 V for 120, 200 and 240 Vac systems, and 600 V for 400, 480, and
590 Vac systems.

6. Input/output wire gauge must be based on a minimum of either 150% (QC1000/2000) or 125%
(QC3000) of the rated input/output current of the drive, and a minimum 75°C insulation rating. Use
copper wire only.

7. Wire and ground in accordance with NEC or CEC, and all applicable local codes.

12.0 INITIAL POWER UP

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

Hazard of electrical shock! Disconnect incoming power and wait three minutes before servicing drive.
Capacitors retain charge after power is remov e d .

Before attempting to operate the drive, motor, and driven equipment be sure all procedures pertaining to
installation and wiring have been properly followed. Before powering up the drive for the first time, wire
the drive for operation via the keypad (see Section 13.0 - KEYPAD CONTROL), then follow the
procedures below.

Severe damage to the drive can result if it is operated after a long period of storage or inactivity without
reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding one year (due to storage,
etc), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive
leakage current. This can result in premature failure of the capacitors if the drive is operated after such a
long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply
input power to the drive for 2 hours prior to actually operating the drive/motor system.

Disconnect the driven load from the motor. Verify that the drive input terminals (L1, L2, and L3) are
wired to the proper input voltage per the nameplate rating of the drive.

WARNING!

WARNING!

WARNING!

Incoming AC power MUST NOT be connected to output terminals T1, T2, and T3! Do not cycle input
power to the drive more than once every two minutes.

Energize the incoming power line. The LCD display should light and flash TESTING and the voltage
and horsepower rating of the drive. The display should then show the following:

STOP 20.00 HZ

0% LOAD FWD KEY

This display in dicates that the drive is stopped, the present speed setpoint is 20.00 Hz, there is no load on
the drive (because it is stopped), forward rotation is selected, an d speed contr ol is from the keypad. If the
display does not appear, remove the incoming power, wait three minutes for the bus capacitors to
discharge, and verify correct installation and wiring. If the wiring is correct, re-apply incoming power
and note the display for drive status. If the display still does not appear, refer to Section 20.0 ­TROUBLESHOOTING, or call the factory for assistance. If th e drive powers up correctly, follow the
procedure given below to check the motor rotation:

14.0 CONTROL WIRING

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

14.1 GENERAL

14.1.1 KEYPAD CONTROL

The drive can be controlled by the keypad or by control devices wired to the terminal strip. To operate the
drive from the keypad, refer to Section 13.0 - KEYPAD CONTROL.

14.1.2 CONTROL WIRING VS. POWER WIRING

External control wiring MUST be run in a separate conduit away from all other input and output power
wiring. If control wiring is not kept separate from power wiring, electrical noise may be generated on the
control wiring that could cause erratic drive behavior, possibly resulting in damage to the drive. Use twisted
wires or shielded cable grounded at the drive chassis ONLY.

14.1.3 TB-2: CIRCUIT COMMON

The TB-2 terminals are used as circuit common for the start/stop, forward/reverse, jog, local/remote, analog
input, analog output, and E-stop functions. There are two TB-2 terminals available on the terminal strip, and
they are internally connected to each other on the main control board. If necessary TB-2 may be connected to
chassis ground.

14.1.4 SURGE SUPPRESSION ON RELAYS

Current and voltage surges and spikes in the coils of contactors, relays, solenoids, etc, near or connected to the
drive, can cause erratic drive operation. Therefore, a snubber circuit should be used on coils associated with
the drive. For AC coils, snubbers should consist of a resistor and a capacitor in series across the coil. For DC
coils, a free-wheeling or flyback diode should be placed across the coil. Snubbers are typically available from
the manufacturer of the device.

14.2 REMOTE CONTROL

14.2.1 REMOTE MODE SELECTION

To select the REMOTE mode, DO NOT close terminal TB-7 to TB-2. Closing TB-7 to TB-2 will select the
LOCAL mode.

14.2.2 TWO-WIRE START/STOP CONTROL

A two-wire (maintained contact) start/stop circuit can be accomplished by one of two methods on the QC
Series drive. Follow the appropriate procedure listed below:

FORWARD ROTATION ONLY

1. Select REMOTE mode (see above).

2. Connect a jumper between TB-12A and TB-2 to provide a permanent START command to the drive.

33

3. Connect a jumper between TB-12B and TB-2 to select FORWARD rotation.

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

4. Wire a normally open maintained contact between TB-1 and TB-2. Close this contact to START the

drive, and open this contact to STOP the drive.

FORWARD an d REVERSE ROT A TIO N

1. Selec t REM O TE mode (see a bove ).

2. Program Parameter 66 - ROTATION to FWD + REV to allow rotation in both directions.

3. Connect a jumper between TB-12A and TB-2 to provide a permanent START command to the drive.

4. Select the desired rotation by closing the appr opriate terminal (TB-12B for forward, or TB-12C for

reverse) to TB-2. This can be don e with a toggle switch or equivalent circuit.

5. Wire a normally open maintained contact between TB-1 and TB-2. Close this contact to START the

drive, and open this contact to STOP the drive.

Refer to Section 15.2 for a diagram illustrating a typical two-wire start/stop control.

14.2.3 ALTERNATE START/STOP CONTROL METHOD

This method uses the direction selection contacts (TB-12B and TB-12C) to start and stop the drive. This
is used when only two dry contacts are available and th e user needs to con trol start/stop and direction
functions.

1. Selec t REM O TE mode (see a bove ).

2. Connect a jumper between TB- 1 and TB-2 to de-activate the S T O P inp u t.

3. Connect a jumper between TB-12A and TB-2 to provide a permanent START command to the drive.

4. ENABLE Parameter 70 - AUTO START, or Parameter 71 - RESTART ON FAULT. This will put

the drive into the RUN mode when power is applied. RUN will be flashing and three flashing
question mar ks (???) will appear in th e DIRECTION portion of the display.

5. Wire a normally open maintained con tact between TB-12B and TB-2. Close this contact to START

the drive in FORWARD, and open this contact to STOP the drive.

6. Wire a normally open maintained contact between TB-12C and TB-2. Close this contact to START

the drive in REVERSE, and open this contact to STOP the drive.

NOTE: When a connect ion is mad e between TB-2 an d eit her TB -12B (for war d), or TB- 12C ( rever se) t o
start the drive, the flashing question marks will be replaced by the selected direction indication (FWD or
REV), and the flashin g RUN will change to ACCEL as the drive accelerates t o th e speed set poin t. Wh en
the con nection is opened to stop the drive, the DRIVE STATUS indication will change to DECEL, and
the DIRECTION indication will change back to the three flashing question marks. When the drive
reaches the end of the deceleration ramp, the flashing question marks will remain, and the DRIVE
STATUS indication will return to the flashin g RUN.

Refer to Section 15.3 for a diagram illustrating the alternate start/stop control.

34

14.2.4 THREE-WIRE START/STOP CONTROL

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

A three-wire (momentary contacts) start/stop circuit can be accomplished by following the appropriate
procedure listed below:

FORWARD ROTATION ONLY

1. Selec t REM O TE mode ( s e e above).

2. Conn ect a jump er between TB-12B a nd T B- 2 to select the FO RWARD d irection .

3. Wire a n ormally closed momen tary con tact between TB-1 and TB-2. This is the STOP input. Open
this contact to STOP the drive.

4. Wire a normally open momentary contact between TB-12A an d TB-2. Close this contact to START
the drive.

FORWARD an d REVERSE RO TAT ION

1. Selec t REM O TE mode ( s e e above).

2. Program Parameter 66 - FWD / REV to FWD + REV.

3. Select the desired rotation by closing the appropriat e termina l (TB-12B for forward, or TB-12C for
reverse) to TB-2. This can be done with a toggle switch or equivalent circuit.

4. Wire a normally closed momentary con tact between TB-1 and TB-2. Open this contact to STOP the
drive.

5. Wire a normally open momentary contact between TB-12A an d TB-2. Close this contact to START
the drive.

NOTE: If the opposite direction is selected while the drive is running, the drive will deceler ate t o 0 Hz
and then accelera te back to t he speed s etpoint in the opposite directi on.

Refer to Section 15.4 for a diagram illustrating a typical three-wire star t/stop control.

14.2.5 ANALOG SPEED REFERENCE SI GNALS

The drive allows for three analog speed reference inputs: a speed potentiometer (10 kilohm), 0-10 VDC,
or 4-20 mA.

SPEED POT Connect the wiper to terminal TB-5A, and connect the high and low end leads to

terminals TB-6 and TB-2, respectively.

0-10 VDC Wire the positive to terminal TB-5D and the negative to terminal TB-2.

4-20 mA Wire the positive to terminal TB-5B and the negative to terminal TB-2.

The input impedance of terminal TB-5A (speed pot input) is 100 kilohms, terminal TB-5B (4-20 mA
input) is 100 Ohms, and termin a l TB-5D (0-10 VDC) is 200 kilohms. Termi nal TB-2 is circuit common.

35

14.2.6 SPEED REFERENCE SELECTION

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

To select an AUTOMATIC speed reference, the drive must be in the AUTO mode. This is done by setting
Parameter 67 - AUTO/MAN SEL to either AUTO SPEED, AUTO & MAN LOCAL, or AUTO & MAN
SPEED. When set to AUTO & MAN LOCAL or AUTO & MAN SPEED, the AUTO mode can be
selected using the AUTO/MAN button on the keypad.

Once the drive is in the AUTO mode, a speed reference is selected by closing the appropriate terminal that
corresponds to the desired speed reference to TB-2. Refer to the terminal strip diagram in Section 15.0.

JOG Closing TB-12D to TB-2 will JOG the driv e at the JOG SPEED (Parameter 19 ).

Open TB-12D to TB-2 to STOP the drive.

When operating in JOG mode, the STOP input at TB-1 and the STOP key
stop the drive, the contact between TB-12D and TB-2 must be opened.

SPEED POT Close TB-12E to TB-2 to select speed control by a 10 kilohm potentiometer at

TB-5A.

4-20 mA Close TB-12F to TB-2 to select speed control by a 4-20 mA signal at TB-5B.

use TB-10B. If a 4-20 mA signal is required, program Parameter 50 to 4-20 MA FREQ or 4-20 MA
LOAD, and use T B-10D.

14.2.8 DRIVE STAT US OUTPUT CONTACT S

The control board has two FORM C relays at terminals TB-16, 17, and 18, and TB-19, 20, and 21.
Contacts are rated 2 amps at 28 VDC or 120 Vac.

There is also an open-collector output at terminal TB-14. The open-collector circuit is a current-sinking
type r ated at 30 VDC a nd 40 mA maximum. An external 24 VDC power supply must be used to power
the open-collector output. The drive does n ot h ave a dedicated 24 VDC supply for the open-collector
circuit.

The FORM C relays and th e open-collector output can be programmed to indicate any of the following:
NO FUNCTION, RUN, FAULT, FAULT LOACKOUT, AT SPEED, ABOVE SET SPEED, C URRENT
LIMIT, FOLLOWER PRESENT, MAINTENANCE TARGET, AUTO SPEED MODE, or START
PENDING. See Parameters: 121 - RELAY #1 FUNCTION, 122 - RELAY #2 FUNCTION, and 124 ­TB-14 FUNCTION. Refer to Section 6.2.5 for a complete description of each of these status indications.

14.2.9 EMERGENCY STOP (E-STOP)

Terminal TB-22 is the E-STOP input, which must be closed to TB-2 for the drive to operate. If the
connection between TB-22 and TB-2 is opened, the drive will trip in to an EMERGENCY STOP fault. If
the drive is running when this occurs, the drive will COAST to a stop, even if Parameter 65 - COAST TO
STOP is disabled.

The QC Series drive is shipped from the factory with a jumper between TB-22 and TB-2. If safety
interlocks are to be connected to the drive, remove the factory jumper and install th e interlocks betwen
TB-22 and TB-2.

WARNING!

Do not connect 120 Vac to the control board! Severe damage will result! Use relays to provide dry
contacts to the terminal strip. Only RELAY 1 and RELAY 2 are rated for 120 Vac.

NOTES:

1. Remove the factory jumper between TB-7 and TB-2 to select REMOTE mode.

2. Close TB-1 to TB-2 to START, and open to STOP.

3. If REVERSE direction is required, Parameter 66 - FWD/REV must be set to FWD + REV. If
REVERSE direction is not required, TB-12B (FORWARD) must be wired directly to TB-2.

4. TB-12F (4-20 mA SELECT) must be closed to TB-2 in order for the drive to respond to the 4-20 mA
signal. If TB-12F is not closed to TB-2, speed control will default to the key pad.

5. To connect normally closed safety interlocks, remove the factory E-STOP jumper and wire the
interlocks between TB-22 and TB-2.

WARNING!

Do not connect 120 Vac to the control board! Severe damage will result! Use relays to provide dry

18.0 DESCRIPTION OF PARAMETERS

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

1

The current limit setting determines the maximum value of the output current. This is usually done to limit
motor torque capability. For most applications the current limit is maintained at the maximum setting.
When the drive output current exceeds the CURRENT LIMIT value, the drive will attempt to avoid an
OVERLOAD fault by decelerating the load in an effort to reduce the output current. When the overcurrent
condition passes, the drive will return to normal operation and accelerate back to the speed setpoint.
However, if the drive cannot reduce the current quickly enough by decelerating, it will trip on an
OVERLOAD fault. Also, if the drive enters current limit during acceleration, the time required to reach
the speed setpoint will be longer than the time indicated by the acceleration rate setting (NORMAL
ACCEL, PRESET ACCEL, or JOG ACCEL).

2

The THERMAL OVERLOAD setting is used to protect the moto r from overheating d ue to ex cess current.
The trip time for the THERMAL OVERLOAD setting is based on an "inverse I
emulates a mechanical thermal overload relay (commonly referred to as "heaters").

To determine the correct THERMAL OVERLOAD setting, divide th e full load current rating o f the mo tor
by the output current rating of the drive, and multiply by 150% (for QC1000/2000), or 120% (QC3000).
Entering the resulting percentage in to this parameter will calibrate the ove rload circuitry to the particular
motor, allowing the motor to draw either 150% or 120 % of the motor current rating (rather than the drive
rating) for one minute.

t" function. This function

Example:

HP motor with a full load current rating of 11 amps. Divide the motor current rating by the drive output
current rating and then multiply by 150%: (11.0 / 14.0) X 150% = 118%. Entering this value into the
THERMAL OVERLOAD parameter will allow the motor to operate at 16.5 amps (150% of 11 amps) for
one minute. If the THERMAL OVERLOAD parameter is left at 150%, the motor would be allowed to
operate at 21 amps (150% of 14 amps) for one minute.

3

SLIP COMPENSATION is used to compensate for changes in motor speed ("slip") caused by changes in
load. In a standard AC induction motor, as the load on the motor increases, the motor current increases and
the motor shaft speed decreases. By increasing the output frequency in response to the increased motor
current, motor speed fluctuation can be greatly reduced. Speed regulation with no load to full load
fluctuations of less than 1% of base speed are attainable in most ap plications. SLIP COMPENSATION is
often set to 3% as that is the standard slip rating of most AC induction motors.

4

This parameter selects the output frequency of the drive that will correspond to the minimum analog speed
reference input (4 mA or 0 VDC). This parameter is used in conjunction with Parameter 5 below to define
a speed range for the drive that corresponds to the analog speed reference input (4 - 20 mA or 0 - 10 VDC).

A 10 HP, 480 Vac QC Series drive with an output current rating of 14 amps is operating a 7.5

SPD 20MA/10V

(SPEED AT 20 mA OR 10 VDC)

This parameter selects the output frequency of the drive that will correspond to the maximum analog speed
reference input (20 mA or 10 VDC). This parameter is used in conjunction with Parameter 4 above to
define a speed range that corresponds to the analog speed reference input (4 - 20 mA or 0 - 10 VDC).

NOTE:

The drive can be programmed for inverse operation so that minimum speed reference corresponds
to the maximum output frequency, and the maximum speed reference corresponds to the minimum output
frequency. This is accomplished by setting SPEED 4MA/0 V larger than SPD 20MA/10V. Therefore, as
the speed reference increases, the drive speed will decrease, and as the sp eed referen ce decreases, the dr ive
speed will increase. See the example below.

Example:

The drive is being controlled by a pressure transducer that provides a 4-20 mA signal
proportional to duct pressure. The minimum frequency desired is 20 Hz, and the maximum is 60 Hz. Set
SPEED 4MA/0V for 60 Hz, and SPD 20MA/10V for 20 Hz. As the duct pressure rises, the output signal
from the transducer will increase, cau sing the speed of the drive to decrease. Th is results in a decrease in
duct pressure and a decreasing transducer signal. The drive responds to the decreasing signal by increasing
speed, which again raises the duct pressure. In this way, the average duct pressure can be maintained at a
desired level. If the acceleration and deceleration rates are set too fast however, the drive will react quickly
to signal changes which will cause the drive speed to hunt up and down excessively.

9

PRE. ACC/DEC

(PRESET SPEED ACCEL & DECEL)

This parameter is used to ENABLE or DISABLE the individual acceleration and deceleration times
(Parameters 21-27, and 31-37) for each of the seven preset speeds. When disabled, the preset speeds will
follow the NORMAL ACCEL (Parameter 20) and NORMAL DECEL (Parameter 30) settings.

11-17

PRE #1 SPEED - PRE # 7 SPEED

(PRESET SPEEDS)

Preset speeds are programmable and are activated via contact closures between TB-2 and TB-13A, 13B,
and 13C. Seven preset speeds are available, which can be activated according to the following table:

NORMAL ACCEL

(NORMAL ACCELERATION)

This parameter sets the acceleration time when the speed is controlled from the keypad, a speed pot, 4-20
mA, or 0-10 VDC. It also determines the acceleration rate for the preset speeds if Parameter 9 - PRESET
ACC/DEC is DISABLED. The NORMAL ACCEL setting indicates the time to accelerate from 0 Hz to
BASE FREQUENCY (Parameter 100). The minimum acceleration setting depends on the horsepower
rating of the drive. See the table b elow for the NORMAL ACCEL range of adjustment.

NOTE:

The ability to accelerate a given load at a particular rate will be limited by the output power
capabilities of the drive/motor co mbination. The acceleration of high-inertia and high -friction loads may
be affected by the current limiting characteristics of the drive. See Parameters: 1 - CURRENT LIMIT,
104 - AUTO V BOOST, and 105 - MANUAL BOOST.

However, the value shown in the WITHOUT DB column is the operational limit of a drive without
dynamic braking. For example, NORMAL DECEL can be set as low as 0.8 seconds on a 50 HP drive
without dynamic braking, but the actual minimum deceleration time would be 3.0 seconds.

The parameter can actually be set as low as the value shown in the WITH DB column.

Taper decel varies the deceleration "ramp" in order to increase stopping capacity on high inertia loads.
When this parameter is ENABLED, the deceleration curve is altered from a linear function to the "top half
of an S-curve". During the first part of the deceleration period, when rotational kinetic energy is the
highest, the deceleration rate is slow. During the later part of the deceleration period the deceleration rate
increases, and becomes a linear function once again.

NOTE:

480/400 Vac models 40 HP and below. All other models have this feature built in to the deceleration
function in order to help avoid HI BUS VOLTS faults when decelerating high-inertia loads.

These parameters are used to prevent continuous operation at critical speeds, or frequencies. Critical
frequencies cause mechanical resonance, resulting in excessive vibration of the driven equipment. The
SKIP SPEEDS are used with the SKIP BANDWIDTH to define up to three speed avoida nce ranges. The
SKIP SPEED setting is the mid-point of the speed avo idanc e rang e, while the SKIP BANDWIDTH defin es
the width of the range.

Example:

Hz, and set SKIP BANDWIDTH to 5 Hz. This will result in a speed avoidance range from 17.5 Hz to 22 .5
Hz. If the drive were operating below 17.5 Hz, and then commanded to operate at a speed within the
avoidance range, the drive would accelerate to 17.5 Hz an d remain there until the speed setpoint b ecomes
greater than 22.5 Hz. The drive would then accelerate through the avoidance range to the new setpoint.
Likewise, if the drive were operating above 22.5 Hz, and then commanded to operate at a speed within the
avoidance range, the drive would decelerate to 22.5 Hz and remain there until the speed setpo int becomes
less than 17.5 Hz. The drive would then decelerate through the avoidance range to the new setpoint.

This parameter scales the analog output signal at TB-10B, 10D, and 10E, when set to indicate output
frequency. This setting is the output frequency that will cause the maximum analog outp u t sign al (1 0 VDC
or 20 mA) to be measured at TB-10B, 10D, and 10E.

52

This parameter is used to select the output impedance of the 4-20 mA signal at TB-10D. The total
resistance connected between TB-2 and TB-10D should equal 250 ohms. A series resistor can be added to
accomplish this. When the resistance of the 4 - 20 mA device is less than 250 ohms, and a series resistor
cannot be added, the actual measured resistance needs to be entered here in order to have proper scaling of
the 4 - 20 mA signal.

MAXIMUM FREQUENCY sets the highest outpu t frequenc y at which the d rive will o perate. This is used
in conjunction with Parameter 61 - MINIMUM FREQUENCY to define the operating range of the drive.

If the drive trips, it will attempt to restart after a time delay set by Par ameter 73 - RESTART DELAY. The

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

number of restart attempts is governed by Parameter 72 - RESTART LIMIT. If the drive attempts the
programmed number of restarts, and is unsuccessful, it will display FAULT LOCKOUT. Once the
condition passes that caused the drive to trip (such as high or low input voltage), the FAULT LOCKOUT
can be cleared by pressing the STOP key, issuing a STOP command at TB-1, or cycling input power.

The RESTART ON FAULT function is designed to restart into a spinning motor by conducting a speed
search to catch the motor, and then accelerate it back to the speed setpoint. The speed search is
conducted by first restarting the drive at MAXIMUM FREQUENCY at a reduced voltage. The voltage is
then increased and the motor current rises to a h igh lev el cau sing the d rive to go in to cu rren t limit (b ased on
Parameter 76 - RESTART CURRENT LIMIT). The motor current rises to the current lim it level due to the
differential between the output frequency of the drive and the speed of the spinning motor. The drive
output frequency then decelerates (based on Parameter 75 - RESTART DECEL) until the motor current
drops below the current limit level (this occurs when the drive output frequency matches the motor speed).
Once the output frequency matches the motor speed, the drive has caught the spinning motor and can
accelerate it back to the speed setpoint.

NOTE:

governed by the AUTO START function. Therefore, if it is necessary to start into a spinning motor after a
power outage, enable RESTART ON FAULT, and disable AUTO START.

Automatic starting of equipment may cause damage to equipment and/or injury to personnel! Automatic
start should only be used on equipment that is inaccessible to personnel.

72

The RESTART LIMIT sets the number of times th e drive will attempt to restart after a fault. I f the drive
attempts the programmed numb er of restarts, and is unsuccessful, it will display FAULT LOCKOUT, and
will require a reset via the STOP key, opening TB- 1 to TB-2, or cycling incom in g power.

73

The RESTART DELAY is the time delay between restart attem pts. During this time delay the drive will
display "WARNING! START PENDING". This parameter also determines the time period which must
elapse after a fault before the drive can be reset.

The QC Series drives are dual rated (200/240 Vac, 400/480 Vac, and 480/590 Vac) to allow operation on a
wide range of input voltages. QC1000/2000 Series drives also have dual current ratings to compensate for
lower input voltage, and this parameter must be set correctly to calibrate the thermal overload circuitry.
The selections are described below:

For QC3000 Series drives, set this parameter to 240/480/590, regardless of the input voltage. The QC3000
does not have a dual current rating, and if this parameter is set to 200/400/480, the thermal overload

100

The BASE FREQUENCY is the frequency at which the drive applies full output voltage to the motor. For
most applications the base frequency should be set to the rated frequency of the motor.

The BASE FREQUENCY determines the V/Hz ratio of the drive outpu t. For example, if the drive is rated
for 460 Vac and the BASE FREQUENCY is set to 60 Hz, the drive will maintain a constant ratio of 7.66
V/Hz from 0 to 60 Hz. However, if Parameter 101 - V/HZ CURVE is not set for LINEAR 1.0, the V/Hz
ratio will not be constant. The BOOST parameters (Parameters 104 and 105) also alter the V/Hz ratio.

101

This parameter is used to change the relationship between the output voltage and frequency. Choices are:

AUTO V BOOST

(ACCELERATION BOOST)

AUTO V BOOST overrides the V/Hz setting determined by th e BASE FREQUENCY and V/HZ CURVE
to increase output voltage during acceleration, which increases motor torque. AUTO V BOOST is usually
used in applications with high inertia loads where quick accelerations are desired. Setting AUTO V
BOOST too high may cause erratic drive behavior. Therefore, it should be set to the lowest value that
yields satisfactory performance.

105

MANUAL BOOST

(STARTING BOOST)

The MANUAL BOOST overrides the V/Hz setting determined by the BASE FREQUENCY and V/HZ
CURVE to increase output voltage at lower frequencies, which increases motor torque. MANUAL BOOST
is used in applications which require high starting torque. (e.g. conveyors, lifts, and other loads which have
high static friction or high inertia). As with AUTO V BOOST (Parameter 104), MANUAL BOOST should
be set to the lowest value that yields satisfactory performance, to avoid erratic drive behavior. The default
MANUAL BOOST setting depends on horsep ower. See the table below for the default settings.

NOTE:

Both AUTO V BOOST and MANUAL BOOST will reset to factory d efault settings if Parameter
137 - CARRIER SEL is changed. Therefore, if these parameters are used, they must be re-programmed
after the carrier frequency is changed. Also, the amount of boost required to achieve the same performance
may be different after the carrier frequency is changed.

This parameter is used with the serial communications feature. When using this feature, the inverter can
communicate with a personal computer (PC), programmable logic controller (PLC), or other external
device that utilizes RS-232, or RS-485 serial communications for control. The serial interface may be used
to read present parameter settings (uploading to the control device), write new parameter settings
(downloading from the control device), monitor present drive activity, and control current drive activity.
These settings also allow use of the serial interface as a diagnostic tool.

This parameter selects the drive operations that are valid from an external control device over the serial
link. This parameter can be set to the following access levels: DISABLED, DETECT, MONITOR ONLY,
PROGRAM, CONTROL, PROGRAM & CONTROL. If the serial communications feature is not being
used, leave this parameter set to the default setting of PROGRAM.

DISABLED The serial port is inactive and will not respond to any requests from the external

version level. This allows the drives to be included in an RS-485 network, even
if they are not to be monitored, programmed, or controlled via the serial link.

MONITOR ONLY In addition to drive type identification and software version, present drive status

and the present drive parameter settings can be read. This function only allows
reading information from the drive.

PROGRAM The drive will accept updated parameter values from the external device.

Additionally, all MONITOR functions are available.

CONTROL The drive will accept control commands from the external control device, and

will not accept PROGRAM functions. Additionally, all MONITOR functions
are available.

PROG. & CONTROL All PROGRAM, CONTROL, and MONITOR functions are available.

If developing an application for a serial control device, refer to the QC Series Modbus Communications
Specification, or the Qc Series Metasys N2 System Protocol Specification. Standard QC Series drives are
configured for RS-232 and are Modbus compatible. Metasys compatibility and RS-485 are optional.

146

This parameter is used with the serial communications feature. The drive has an internal "watchdog timer"
that is active when an external device has control of the drive via the serial interface, Parameter 145 ­SERIAL COMMUNICATIONS is set to either CONTROL or PROGRAM & CONTROL, and an active
control link is established. During an active control link there is control and “handshake” information that
is passed back and forth between the control device and the drive. If the serial link is broken, for a time
period exceeding the SERIAL TIMEOUT, the drive will automatically stop and return to local ope ratio n.

NOTE:

Though setting this parameter to 0 SEC may be appropriate during setup, CAUTION should be used, since
a setting of 0 SEC will allow the drive to operate via the serial link without a failsafe mechanism.

The SERIAL TIMEOUT function should always be enabled for normal serial link operation.

147

This parameter is used with the serial communications feature, an d is intended for use in a multiple drive
network (RS-485). The serial link will support drives with addresses from 1 up to 247 (Modbus) or 255

19.1 DYNAMIC BRAKING

In ap plicat ions where h igh in ertia loads n eed to be decelera ted qui ckly, or th ere is a n overh aulin g load,
dynamic braking may be required. High inertia and over hauling loads can regenerate voltage back into
the drive, causing the DC bus voltage to rise, which eventually results in a HIGH BUS VOLTS fault.
Dynamic braking dissipates this regen erated energy as h eat through resistors in order to maintain the DC
bus voltage below the trip level. When the dynamic braking circuitry senses that the DC bus voltage has
become too high , a tran sistor is tur ned on which connects the resi stors acr oss th e DC bus. Th e excess
energy bleeds off through the resistors, bringing the DC bus voltage back down to the nominal level.

The QC Series drives can be equipped with either standard duty or heavy duty dynamic braking,
depending on the requirements of the application. Some applications which typically require dynamic
braking are: elevators, escalators, con veyors, large cen trifugal fans, pun ch presses, cran es and hoists,
mach i n e tool s, etc. Ap pl ica t ion s s uch a s el evat or s, es cal a tor s, and cr anes would r eq ui r e d yna mi c bra k in g
during periods when the load is being lowered to counteract the overhauling effects of gravity. High
inertia loa ds such as con veyors and machine tools woul d need dyn amic braking if quick deceler ation times
are required. However, if the load can be allowed to coast to a stop, dynamic braking would not be
necessary.

19.1.1 STANDARD DUTY DYNAMIC BRAKING

The standard duty dynamic braking option consists of a NEMA 1 enclosure and resistors which are
mounted to their own heatsink. T he assembly is designed to mount on top of the QC1000 dr ives. For
applications requiring NEMA 12 or NEMA 4 protection, refer to 19.2 - HEAVY DUTY DYNAMIC
BRAKING below. Care must be taken to ensure adequate ventilation.

The resistor assembly is electrically connected to the drive usin g two wir es, which should be run down the
inside righ t han d side of the drive enclosure and connect to DB1 and DB2 on the power board. Conn ect
the RED wire to DB1 and the BLUE wire to DB2.

Parameter 86 - DYNAMIC BRAKE m ust be ENABLED for the dynam i c brakin g to operate.

Standard duty dynamic braking is not recommended for continuous cycling applications which require
stopping inertial loads greater than twice that of the motor, or more than eight times from 1800 RPM, four
times from 2500 RPM, or two times from 3600 RPM, within a five minute period.

The table below shows the additional height of the drive as a result of the standard duty braking option:

19.1.2 HEAVY DUTY DYNAMIC BRAKING

Phone: [phone] - Fax: [phone] - www.ctiautomation.net - e.mail: [e-mail]

The heavy duty dynamic braki ng option is capable of pr oviding more frequent stopping, and stopping of
higher inertia loads than the standard duty dynamic braking option. The heavy duty braking option
consists of a r esistor assembly and a NEMA 1 enclosure, wh ich is designed to be mounted near the drive,
but not on top of the drive. The resistors are not mounted to a h eatsink, but include mounting brackets.
The resis tors a nd enclosure are sh ipped loose when order ed with a drive.

For NEMA 12 or NEMA 4 applications, the resistors must be mounted in an appropriate enclosure of
sufficient size to dissipate the generated heat. Care must be taken to ensure adequate ventilation.

As with the standard duty brakin g option, two wires need to be connected to the power board in the drive.
These should be run in rigid metal conduit fr om the braking assembly to the drive. Connect the RED wire
to DB1, and the BLUE wi re to DB2 on the power board.

Parameter 86 - DYNAMIC BRAKE must be ENABLED for the dynam i c brakin g to operate.

Heavy duty dynamic braking is not recommended for continuous cycling applications which require
stopping inertial loads greater than twice that of the motor, or more than eight times from 1800 RPM, four
times from 2500 RPM, or two times from 3600 RPM, within a one minute period.

Heavy duty dyna mic braking can provide 100% of motor torque continuously for output frequencies up to
15 Hz, 50% continuously up to 30 Hz, or 25% continuously up to 60 Hz.

Heavy duty dynamic braking can also provide 180% of motor torque for 30 seconds per minute at output
frequencies up to 15 Hz , 15 seconds per minut e up to 30 Hz, or 7 seconds per minute up to 60 Hz.

NOTE: Con s ult the fa ctor y when dyna mic bra king is requ ir e d on drive m odels above 15 HP .
