5 MC3000 RATINGS

The following tables indicate the input and output ratings of the MC3000 Series drive.
NOTE: The output current ratings are based on operation at carrier frequencies of 8 kHz

and below. At full ambient temperature, operation at carrier frequencies above
8 kHz requires derating the drive by multiplying the output current rating by the
following factors: 0.94 at 10 kHz, 0.89 at 12 kHz, and 0.83 at 14 kHz. Refer to
Parameter 23 - CARRIER in Section 18 - DESCRIPTION OF PARAMETERS.

6 THEORY

6.1 DESCRIPTION OF AC MOTOR OPERATION

Three phase AC motors are comprised of two major components, the stator and the rotor.
The stator is a set of three electrical windings held stationary in the motor housing. The
rotor is a metal cylinder, fixed to the motor drive shaft, which rotates within the stator.
The arrangement 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. Synchronous speed is a
function of the frequency 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

Where: Ss = Synchronous speed (rpm)
f = frequency (Hz)

p = number 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 rotor 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 obtained by maintaining a constant ratio between
voltage amplitude (Volts) and frequency (Hertz). For 60 Hz motors rated at 230, 460,
and 575 Vac, common values for this V/Hz ratio are 3.83, 7.66, and 9.58 respectively.
Operating with these V/Hz ratios generally yields optimum torque capability. Operating at
lower ratio values results in lower torque and power capability. Operating at higher ratio
values 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 cooling fans
become less effective, supplemental cooling may be needed to operate at full torque
output continuously.

If the frequency 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 approximately constant. Motors run in this mode when
operated above base speed, where drive output voltage is limited by the input 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 characteristics of a typical AC induction motor with a 60 Hz base speed.

WARNING!

Consult motor manufacturer before operating motor and/or driven
equipment above base speed.

6.1.1 VARIABLE TORQUE VS. CONSTANT TORQUE
Variable frequency drives, and the loads they are 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.

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

“Variable torque” refers to the fact that the torque required varies with the square of the
speed. Also, the 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. Variable torque drives usually have a low
overload capacity (110% - 120% for 60 seconds), because variable torque applications
rarely experience overload conditions. To optimize efficiency and energy savings, variable
torque drives are usually programmed to follow a variable V/Hz ratio.

The term “constant torque” is not entirely accurate in terms of the actual torque required
for an application. Many constant torque applications have reciprocating loads, such
as vibrating conveyors and punch presses, where the rotational motion of the motor is
being converted to a linear motion. In such cases, the torque required can vary greatly at
different points in the cycle. For constant torque loads, this fluctuation in torque is not a
direct function of speed, as it is with a variable torque load. As a result, constant torque
drives typically have a high overload rating (150% for 60 seconds) in order to handle
the higher peak torque demands. To achieve maximum torque, constant torque drives
follow a constant V/Hz ratio.

Both MC Series product lines (MC1000 and MC3000) have full overload capacity (150%
for 60 seconds, 180% for 30 seconds), so that either one can be used for either type of
application. The V/Hz ratio can also be changed to optimize performance for either type
of application.

6.2 DRIVE FUNCTION DESCRIPTION

The MC Series is a 16 bit microprocessor based, keypad programmable, variable speed
AC motor drive. There are four major sections: an input diode bridge and 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-up. The pulsating DC voltage
is filtered by the bus capacitors which reduces the ripple level. The filtered DC voltage
enters the inverter section of the drive, composed of six output intelligent insulated gate
bi-polar transistors (IGBTs) 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 the serial communications port. The Power Board
contains the control and protection circuits which govern the six output IGBTs. The Power
Board also contains a charging circuit for 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 MC3000 INPUTS AND OUTPUTS

The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed
reference, PID setpoint reference, or PID feedback. A speed potentiometer (10,000 ohm)
can be used with the 0-10 VDC input.

There are also two analog outputs: one is proportional to speed (frequency), and the
other is proportional to load.

The drive has three programmable outputs for status indication: one Form C relay and
two open-collector outputs.

Refer to Sections 14 - CONTROL WIRING and 15 - CONTROL WIRING DIAGRAMS
for more information.

7 INSTALLATION

WARNING!

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 Lenze AC Tech 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 that 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 as follows:

SPACING REQUIREMENTS

HP

SPACING

INCHES mm

0.25 - 5 2 50

7.5 - 25 4 100

30 - 60 6 150

All drive models MUST be mounted in a vertical position for proper heatsink cooling.
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.

If it is necessary to drill or cut the drive enclosure or panel, extreme care must be taken
to avoid damaging 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.

The MC3000 Series is UL approved for solid state motor overload protection. Therefore, a
separate thermal overload relay is not required for single motor applications. In applications
where one drive is operating more than one motor, a separate thermal overload relay is
required for each motor per NEC.

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 three
years (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 8 hours prior to actually operating the
drive/motor system.

7.2 EXPLOSION PROOF APPLICATIONS

Explosion proof motors that are not rated for inverter use lose their certification when
used for variable speed. Due to the many areas of liability that may be encountered when
dealing with these applications, the following statement of policy applies:

"Lenze AC Tech Corporation inverter products are sold with no warranty of fitness for a
particular purpose or warranty of suitability for use with explosion proof motors. Lenze
AC Tech Corporation accepts no responsibility for any direct, incidental or consequential

8 INPUT AC REQUIREMENTS

WARNING!

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 input voltage must match the drive’s nameplate 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 0 - LINE VOLTS in Section
18 - DESCRIPTION OF PARAMETERS.

The UL file for this drive shows that it is suitable for use on a circuit capable of delivering
not more than 200,000 RMS symmetrical amperes, at the drive’s rated voltage. The CSA
file identifies a short-circuit withstand rating of 5,000 RMS symmetrical amperes at the
drives 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 SUPPLY TRANSFORMER 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.

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 MC3000 drive is capable of withstanding up to 150% current overload for 60 seconds.
Select a fuse or magnetic trip circuit breaker rated at 1.5 times the input current rating
of the drive (the minimum size should be 10 amps, regardless of input current rating).
Refer to Section 5 – MC3000 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.

Current limiting type fuses should be used when input fusing is required. Select fuses
with low I

2

T values, rated at 200,000 AIC. Recommended fuses are Bussman type
kTk-R, JJN or JJS. Similar fuses with equivalent ratings by other manufacturers may
also be acceptable.

10 POWER WIRING

WARNING!

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

Note the drive input and output current ratings and check applicable electrical codes for
required wire type and size, grounding requirements, overcurrent protection, and incoming
power disconnect, before wiring the drive. Size conservatively to minimize 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 Lenze AC Tech 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 240/120 Vac single phase input, wire the input to terminals
L1 and N and jumper terminals L1 to L2 for 120 Vac input voltage, or wire to terminals
L1 and L2 (do not wire to N) for 240 Vac input voltage. Refer to Section 11 - MC3000
POWER WIRING DIAGRAM.

If the drive is nameplated for three phase input only, wire the 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 power and control 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
26 - 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 device is closed.
