6.0THEORY

6.1DESCRIPTION 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..

17

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.

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

6.1.1VARIABLE 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..

6.2DRIVE 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..

6.2.1DRIVE 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.

6.2.2CIRCUIT 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..

19

6.2.3MICRO SERIES INPUTS AND OUTPUTS

The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed reference, PID set point 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..

20

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 set point 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
	REFERENCE SELECTION..

7.0INSTALLATION

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 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.

Maintain a minimum spacing around the drive as follows:

SPACING REQUIREMENTS

	SPACING
HP	INCHES		mm
0..25 - 5	2		50
7..5 - 25	4		100
30 - 60	6		150
75 - 150	8		200

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..

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..

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 MICRO 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.

22

7.1INSTALLATION 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 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..

7.2EXPLOSION 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.”

23

8.0INPUT 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..

8.1INPUT AC POWER REQUIREMENTS

8.1.1VOLTAGE:

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..

8.1.2SUPPLY 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.

8.2INPUT 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 200,000 AIC. Recommended fuses are Bussman type KTK-R, JJN, JJS or equivalent. Similar fuses with equivalent ratings by other manufacturers may also be acceptable.

10.0 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 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 or to isolate 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.

10.1WIRING 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..
