6.0 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.
13
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
operating characteristics of a typical AC induction motor with a 60 Hz base speed.
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.
MICRO Series product lines 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 MICRO Series is a 16 bit microprocessor based, keypad programmable, variable speed AC motor drive.
There are four major sections; an input diode bridge and a 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 (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 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.
15
6.2.3 MC1000 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 14.0 - CONTROL WIRING and 15.0 - CONTROL WIRING DIAGRAMS for more
information.
16
The following describes the possible relay output settings:
NONE 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
decelerated to 0.5 Hz, the drive has "tripped", or the input voltage 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 turning.
FAULT The relay energizes when input voltage is applied to the drive and remains
energized until the drive "trips" into a fault condition, or input voltage is removed.
/FAULT INVERSE FAULT - The relay energizes when the drive trips into a fault
condition, and remains energized until the fault condition is cleared.
LOCK FAULT LOCKOUT - This relay is 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 five restarts, or input voltage is removed.
@SPEED 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
actual speed and the speed setpoint differ by 3 Hz.
ABOVE #3 The relay energizes when the output frequency of the drive exceeds the value
corresponding to the SPEED #3 value, and de-energizes when the output
frequency returns to a value lower than the SPEED #3 value. See Parameter 3 SPEED #3 in Section 18.0 - DESCRIPTION OF PARAMETERS.
I LIMIT 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 16 - CURRENT in Section 18.0 - DESCRIPTION
OF PARAMETERS.
AUT/MAN The relay energizes when the drive is in the AUTOMATIC mode, and
de-energizes in the MANUAL mode. Refer to Section 14.2.6 - SPEED

7.0 INSTALLATION
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 LEESON 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. 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.
Maintain a minimum spacing around the drive as follows:
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.

7.1 INSTALLATION AFTER A LONG PERIOD OF STORAGE
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 6 months (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.
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:
"LEESON Electric inverter products are sold with no warranty of fitness for a particular purpose or
warranty of suitability for use with explosion proof motors. LEESON Electric accepts no
responsibility for any direct, or incidental or consequential loss, cost, or damage that may arise
through the use of its AC inverter products in these applications. The purchaser expressly agrees to
assume all risk of any loss, cost, or damage that may arise from such application. LEESON Electric
or LEESON Electric's engineering department will not knowingly approve applications involving
explosion proof motors."

WARNING
8.0 INPUT AC REQUIREMENTS
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 18.0 - DESCRIPTION OF PARAMETERS SECTION.
The drive is suitable for use on a circuit capable of delivering not more than 18,000 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 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 MICRO Series 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 5.0 - 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 VAC drives.
Current limiting type fuses should be used when input fusing is required. Select Class CC or Class T fuses
with low I2T value, rated at 2,000,000 AIC. Recommended fuses are Bussman type KTK-R, JJN, JJS or
equivalent. Similar fuses with equivalent ratings by other manufacturers may also be acceptable.

input voltages of 480 to 590 Vac (+10%, -15%), at 48 to 62 Hz.
NOTE: Parameter 0 - LINE VOLTS must be programmed according to the applied input voltage. See
Section 18.0 - DESCRIPTION OF PARAMETERS.
10.0 POWER WIRING
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 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 LEESON Electric, 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 11.0 - MICRO SERIES 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.
Do not install contactors between the drive and motor without consulting LEESON Electric for more
information.
21
WARNING
11.0 MICRO SERIES POWER WIRING DIAGRAM
