!Caution Do not stop operation by switching OFF electromagnetic contactors on theprimary or secondary side of the inverter.

When there has been a sudden power failure while an operation instruction isactive, then the unit may restart operation automatically after the power failurehas ended. If there is a possibility that such an occurrence may harm humans,then install an electromagnetic contactor (Mgo) on the power supply side, sothat the circuit does not allow automatic restarting after the power supplyrecovers. If the optional remote operator is used and the retry function hasbeen selected, this will also cause automatic restarting when a Run commandis active. So, please be careful.

!Caution Do not insert leading power factor capacitors or surge absorbers between theoutput terminals of the inverter and motor.

!Caution EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTERIn the case below involving a general-purpose inverter, a large peak currentcan flow on the power supply side, sometimes destroying the converter mod-ule:

1. The unbalance factor of the power supply is 3% or higher.

2. the power supply capacity is at least 10 times greater than the inverter ca-pacity (or the power supply capacity is 500 kVA or more).

3. Abrupt power supply changes are expected, due to conditions such as:

a) Several inverters are interconnected with a short bus.

b) A thyristor converter and an inverter are interconnected with a shortbus.

c) An installed phase advance capacitor opens and closes.

Where these conditions exist or when the connected equipment must behighly reliable, you MUST install an input side AC-reactor of 3% (at a voltagedrop at rated current) with respect to the supply voltage on the power supplyside. Also, where the effects of an indirect lightening strike are possible, installa lightening conductor.

!Caution SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTERThe inverter uses many semiconductor switching elements such as transis-tors and IGBTs. Thus, a radio receiver or measuring instrument located nearthe inverter is susceptible to noise interference.

To protect the instruments from erroneous operation due to noise interfer-ence, they should be used well away from the inverter. It is also effective toshield the whole inverter structure.

The addition of an EMI filter on the input side of the inverter also reduces theeffect of noise from the commercial power line on external devices.

Note that the external dispersion of noise from the power line can be mini-mized by connecting an EMI filter on the primary side of the inverter.

!Caution When the EEPROM error E08 occurs, be sure to confirm the setting valuesagain.

1-2 MX2 Inverter Specifications

1-2-1 Model-specific tables for 200 V and 400 V class invertersThe following tables are specific to MX2 inverters for the 200 V and 400 Vclass model groups. Note that General Specifications on page 7 in this chap-ter apply to both voltage class groups. Footnotes for all specification tables fol-low the table below.

Footnotes for the preceding table and the tables that follow:

Note 1 The protection method conforms to JEM 1030.

Note 2 The applicable motor refers to a standard 3-phase motor (4p). When usingother motors, care must be taken to prevent the rated motor current (50/60 Hz) from exceeding the rated output current of the inverter.

Note 3 The output voltage decreases as the main supply voltage decreases (exceptwhen using the AVR function). In any case, the output voltage cannot exceedthe input power supply voltage.

Note 4 To operate the motor beyond 50/60 Hz, consult the motor manufacturer for themaximum allowable rotation speed.

Note 5 For achieving approved input voltage rating categories:

• 460 to 480 VAC - Over-voltage category 2

• 380 to 460 VAC - Over-voltage category 3

To meet the Over-voltage category 3, insert an EN or IEC standard compliantisolation transformer that is earth grounded and star connected (for LowVoltage Directive).

Note 6 At the rated voltage when using a standard 3-phase, 4-pole motor.

Note 7 The braking torque via capacitive feedback is the average deceleration torqueat the shortest deceleration (stopping from 50/60 Hz as indicated). It is notcontinuous regenerative braking torque. The average deceleration torque var-ies with motor loss. This value decreases when operating beyond 50 Hz. If alarge regenerative torque is required, the optional regenerative braking unitand a resistor should be used.

Note 8 The frequency command is the maximum frequency at 9.8 V for input voltage0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic isnot satisfactory for your application, contact your Omron representative.

Note 9 If the inverter is operated outside the region shown in the graph in the deratingcurve, the inverter may be damaged or its service life may be shortened. Set Carrier Frequency Adjustment in accordance with the expected outputcurrent level. See derating curve section for the detailed information of theinverter operating range.

Note 10 The storage temperature refers to the short-term temperature during transpor-tation.

Note 11 Conforms to the test method specified in JIS C0040 (1999). For the modeltypes excluded in the standard specifications, contact your Omron sales rep-resentative.

Note 12 Watt losses are calculated values based on specification of main semi-con-ductors. You must take suitable margin when designing cabinet based onthese values. Otherwise there is a possibility of heating trouble.

1-2-3 Signal RatingsDetailed ratings are in .

1-2-4 Derating CurvesThe maximum available inverter current output is limited by the carrier fre-quency and ambient temperature. Choosing a higher carrier frequency tendsto decrease audible noise, but it also increases the internal heating of theinverter, thus decreasing (derating) the maximum current output capability.Ambient temperature is the temperature just outside the inverter housing suchas inside the control cabinet where the inverter is mounted. A higher ambienttemperature decreases (derates) the inverter's maximum current outputcapacity.

An inverter up to 4.0 kW may be mounted individually in an enclosure or side-by-side with other inverter(s) as shown below. Side-by-side mounting causesgreater derating than mounting inverters separately. Graphs for either mount-ing methods are included in this section. Refer to Installation Environmentclearance on page 31 for minimum clearance dimensions for both mountingconfigurations.

1-3 Introduction to Variable-Frequency Drives

1-3-1 The Purpose of Motor Speed Control for IndustryOmron inverters provide speed control for 3-phase AC induction motors. Youconnect AC power to the inverter, and connect the inverter to the motor. Manyapplications benefit from a motor with variable speed, in several ways:

• Energy savings - HVAC

• Need to coordinate speed with an adjacent process - textile and printingpresses

• Need to control acceleration and deceleration (torque)

• Sensitive loads - elevators, food processing, pharmaceuticals

1-3-2 What is an InverterThe term inverter and variable-frequency drive are related and somewhatinterchangeable. An electronic motor drive for an AC motor can control themotor's speed by varying the frequency of the power sent to the motor.

An inverter, in general, is a device that converts DC power to AC power. Thefigure below shows how the variable-frequency drive employs an internalinverter. The drive first converts incoming AC power to DC through a rectifierbridge, creating an internal DC bus voltage. Then the inverter circuit convertsthe DC back to AC again to power the motor. The special inverter can vary itsoutput frequency and voltage according to the desired motor speed.

The simplified drawing of the inverter shows three double-throw switches. InOmron inverters, the switches are actually IGBTs (insulated gate bipolar tran-sistors). Using a commutation algorithm, the microprocessor in the driveswitches the IGBTs on and off at a very high speed to create the desired out-put waveforms. The inductance of the motor windings helps smooth out thepulses.

1-3-3 Torque and Constant Volts/Hertz OperationIn the past, AC variable speed drives usedan open loop (scalar) technique to controlspeed. The constant-volts-hertz operationmaintains a constant ratio between theapplied voltage and the applied frequency.With these conditions, AC induction motorsinherently delivered constant torque acrossthe operating speed range. For some appli-cations, this scalar technique was ade-quate.

Introduction to Variable-Frequency Drives Section 1-3

Today, with the advent of sophisticated microprocessors and digital signal pro-cessors (DSPs), it is possible to control the speed and torque of AC inductionmotors with unprecedented accuracy. The MX2 utilizes these devices to per-form complex mathematical calculations required to achieve superior perfor-mance. You can choose various torque curves to fit the needs of yourapplication. Constant torque applies the same torque level across the fre-quency (speed) range. Variable torque, also called reduced torque, lowers thetorque delivered at mid-level frequencies. A torque boost setting will add addi-tional torque in the lower half of the frequency range for the constant and vari-able torque curves. With the free-setting torque curve feature, you can specifya series of data points that will define a custom torque curve to fit your appli-cation.

1-3-4 Inverter Input and Three-phase PowerThe Omron MX2 Series of inverters includes two sub-groups: the 200 V classand the 400V class inverters. The drive described in this manual may be usedin either the United States or Europe, although the exact voltage level for com-mercial power may be slightly different from country to country. Accordingly, a200 V class inverter requires (nominal) 200 to 240 VAC, and 400 V classinverter requires from 380 to 480 VAC.

The 200 V class inverters MX2-B accept single-phase 200 V class input volt-age, those MX2-2 three-phase power only. All 400 V class inverters requirethree-phase power supply.

!Tip If your application only has single phase power available, refer to MX2 inverterof 3HP or less; they can accept single phase input power. Note: Larger mod-els may be able to accept single-phase with derating. Contact your Omrondistributor for assistance.

The common terminology for single phase power is line (L) and Neutral (N).Three-phase power connections are usually labeled Line 1 [R/L1], Line 2 [S/L2] and Line 3 [T/L3]. In any case, the power source should include an earthground connection. That ground connection will need to connect to theinverter chassis and to the motor frame (see “Wire the Inverter Output toMotor” in section 2-3-12 (page 51) and “Inverter output terminal (U/T1, V/T2,W/T3)” i
