Additionally there may be severe property damage. CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Alert Symbols in this Document WARNING Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury due to an electric shock. Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious injury due to an electric shock. Do not put on or take off the Digital Operator•control circuit terminal block•terminal block cover while the input power is being supplied. Doing so may result in a serious injury due to an electric shock. Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire. (200-V class: type-D grounding, 400-V class: type-C grounding) Do not remove the terminal block cover during the power supply and 5 minutes after the power shutoff. Doing so may result in a serious injury due to an electric shock. Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious injury due to an electric shock. Do not change wiring, mode change switches, optional devices or replace cooling fans while power is being supplied. Doing so may result in a serious injury due to an electric shock. 5 Safety Precautions CAUTION Do not connect resistors to the terminals (+1, P/+2, N/-) directly. Doing so might result in a small-scale fire, heat generation or damage to the unit. Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding brake is not a stop motion device designed to ensure safety.) Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is detected in the braking resistor/regenerative braking unit. The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or other property. Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring. Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the power supply and for some time after the power shutoff. Doing so may result in a burn. Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the Inverter capacity on the power supply side. Not doing so might result in damage to property due to the short circuit of the load. Do not dismantle, repair or modify this product. Doing so may result in an injury. 6 Precautions for Safe Use Precautions for Safe Use Installation and Storage Do not store or use the product in the following places. •Locations subject to direct sunlight. •Locations subject to ambient temperature exceeding the specifications. •Locations subject to relative humidity exceeding the specifications. •Locations subject to condensation due to severe temperature fluctuations. •Locations subject to corrosive or flammable gases. •Locations subject to exposure to combustibles. •Locations subject to dust (especially iron dust) or salts. •Locations subject to exposure to water, oil, or chemicals. •Locations subject to shock or vibration.

Note 1: Install an earth leakage breaker on the power supply input side. (Select an earth leakage breaker having a larger high-frequency sensed current and avoid unnecessary operations.) If the wiring between the Inverter and the motor is too long (longer than 10 m), the thermal relay may malfunction due to harmonics. Install an AC reactor on the Inverter output side, or use a current sensor instead of the thermal relay. Note 2: Connect securely to the ground as specified (type-D grounding for 200-V class, and type-C grounding for 400-V class).

(In the case of stranded wires, make sure that the wires are not unraveled.) • Make sure that the maximum outside coating diameter of the signal line is 2.0 mm or less (except for the alarm signal line). (For the mark tube mounted cable and multi-core cable, keep both the mark tube and the sheathstripped length 40 mm or more from the connecting end. A thick line may prevent proper closing of the cover of the terminal block.) • To meet the UL standards, always insert a UL-standard fuse (J type) on the power supply side. • Use a ground wire with a larger diameter than that of the power cable shown above. 2-15 2-3 Wiring Choose the sensitivity current of the earth leakage breaker (ELB), depending on the total distance (L) between the Inverter and the power supply, and the Inverter and the motor.

Due to the higher specific inductive capacity of the H-IV wire, the leakage current increases about eight times. Use a wire with a sensitivity current one-level higher. The leakage current mentioned here is the effective value of the fundamental wave, and high-frequency currents are excluded.

MC X2 OFF ON X1 DC (24 V) relay * Terminal symbols for 3G3MX-AE are indicated in parentheses ( ). Installing a Ground Fault Interrupter •The Inverter's output uses high-speed switching, and so generates high-frequency current leakage. (Generally, if the power cable is 1 m, the leakage current is approx. 100 mA per Inverter, and approx. 5 mA is added per additional meter.) •At the power supply input part, install a special-purpose ground fault interrupter for Inverters that exclude high-frequency leakage current and detect only the leakage current within a frequency range that is hazardous to humans. (Choose a ground fault interrupter with a sensitivity current of at least 10 mA per Inverter.) •Alternatively, use a general ground fault interrupter with a sensitivity current of 200 mA or more per Inverter, and with an operating time of 0.1 s or more. Installing a Magnetic Contactor (MC) •If the power supply of the main circuit is shut off due to sequencing, a magnetic contactor (MC) can be used. (When forcibly stopping the load with an MC on the primary side of the main circuit, however, the regenerative braking does not work and the load coasts to a stop (free run).) •Frequently opening and closing the magnetic contactor (MC) to start and stop a load may cause the Inverter to break down. To extend the life of the Inverter's internal electrolytic capacitor, limit the frequency to no more than once every 30 minutes. Connection Sequence to the Terminal Block •Input power supply can be connected to any terminal because the phase sequence of the input power supply is irrelevant to that of the terminal block (R/L1, S/L2, and T/L3). 2-18 2 Design •Always connect the Inverter and power supply via a molded-case circuit breaker (MCCB) to protect the Inverter from damage that may result from short-circuiting. •Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an MCCB, according to the Inverter capacity. •Install one MCCB per Inverter. •Choose an appropriate MCCB capacity according to the fuse size on page 2-15. •When choosing an MCCB's time characteristics, be sure to consider the Inverter's overload protection (1 minute at 150% of the rated output current). •By programming the sequence as illustrated below, you can turn off the power via the relay outputs (MA, MB, and MC) for the 3G3MX Series. 2-3 Wiring Installing an AC Reactor •If the Inverter is connected to a large-capacity power transformer (660 kVA or more) or the phase advance capacitor is in use, a large peak current may flow through the input power circuit, causing the converter unit to break down. •Install an optional AC reactor on the input side of the Inverter. An AC reactor will also improve the power factor of the power input side. 2 Installing a Surge Absorber Design •Always use a surge absorber or diode when magnetic contactors (MC), electromagnetic relays, solenoid valves, solenoid, and magnetic brakes are used. Connecting a Regenerative Braking Unit When running a load with a large inertia or a vertical axis, regenerative energy will return to the Inverter. If overvoltage in the main circuit is generated during deceleration, this indicates that the regenerative energy exceeds the capacity of the Inverter. In this case, use a regenerative braking unit. •When using a regenerative braking unit, be sure to include a sequence whereby the power supply for the Inverter will be turned off in the event of abnormal overheating. Not doing so may result in fire. For a regenerative braking unit: Use the error contact output (MA, MB).

(Installing a noise filter on the input side can also reduce the noise from the power line to the Inverter.) 2 <Recommended Input Noise Filters for the Inverter> EMC-conforming 3G3AX-NFI 3G3AX-EFI Power supply Design General Molded case circuit-breaker (MCCB) Input noise filter for the Inverter * Inverter 3G3MX M Molded case circuit-breaker (MCCB) Other device * Use a noise filter designed for Inverters. A general-purpose noise filter may be less effective and not reduce noise. 2-20 2-3 Wiring Wiring the Main Circuit Terminals (Output Side) Connect the Terminal Block to the Load •Connect motor output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W. •Check that the motor rotates forward with the forward command. Switch over any two of the output terminals (U/T1, V/T2, W/T3) and reconnect if the motor rotates in reverse to the forward command. 2 Design Never Connect a Power Supply to the Output Terminals •If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged. Never connect a power supply to output terminals U/T1, V/T2, or W/T3. Never Short-circuit or Ground the Output Terminals •Never touch the output terminals by hand. •If the output wires come into contact with metal materials, an electric shock or ground fault will occur. This is extremely hazardous. Be careful not to short-circuit the output wires. Do Not Use a Phase Advance Capacitor or Noise Filter •Doing so may result in damage to the Inverter or cause the parts to burn. Never connect a phase advance capacitor or LC/RC noise filter to the output circuit. Do Not Use an Electromagnetic Switch •If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in the Inverter. Do not connect an electromagnetic switch or magnetic contactor (MC) to the output circuit. Install a Noise Filter on the Output Side Connect a noise filter to the output side of the Inverter to reduce induction and radio noise. Power supply Molded case circuit-breaker (MCCB) Inverter 3G3MX Signal line Noise filter 3G3AX-NFO Induction noise Controller 2-21 M Radio noise AM radio Induction noise: Electromagnetic induction can generate noise on the signal line, causing the controller to malfunction. Radio noise: Electromagnetic waves from the Inverter and I/O cables can cause the radio receiver to generate noise. 2-3 Wiring Countermeasures Against Induction Noise To reduce induction noise from the output side, the following method is also effective. •Run the cables collectively through the mounted metal pipe. Keeping the metal pipe at least 30 cm away from the signal line reduces induction noise. Power supply Molded case circuit-breaker (MCCB) 2 Inverter 3G3MX M Design 30 cm min. Signal line Controller Cable Length Between Inverter and Motor Use a cable of 50 m or less between the Inverter and the motor. If the cable length is increased, the stray capacitance between the Inverter outputs and the ground is increased proportionally. An increase in stray capacitance causes high-frequency leakage current to increase, affecting the current detector in the Inverter's output unit and peripheral devices. If your system configuration requires a cable length of 50 m or more, perform the following: •Wire in metallic ducts. •Use separate cables for each phase. •Set the Inverter to a lower carrier frequency (b083). Do Not Use Single-phase Motors •A single-phase motor uses the capacitor start method or split-phase start method to determine its rotation direction at startup, and thus is not suitable for the variable speed control via the Inverter. Do not use single-phase motors. *If a capacitor start motor is used, the capacitor may be damaged by a sudden electric charge and discharge caused by Inverter output. If a split-phase start motor is used, the startup coil may burn because the centrifugal switch does not operate. 2-22 2-3 Wiring Specifications of Control Circuit Terminals Design 2 Terminal symbol Terminal name and function PSC External power supply terminal for input signal (input) ...At sink logic Internal power supply output terminal for input signal (output) ...At source logic S1 S3 S4 S5 Frequency reference input Select 6 functions among the 30 functions and allocate them to terminals S1 to S6.

For this reason, we make efforts to conform our products to their related EMC standards so that the machines or equipment which have incorporated our products should easily conform to the EMC standards. The 3G3MX models have conformed to the EMC directive EN 61800-3 by following the installation and wiring method as shown below. Your machines or equipment, however, vary in type, and in addition, EMC performance depends on the configuration, wiring, or location of the devices or control panels which incorporate the EC directive conforming products. This in turn does not allow us to confirm the condition and the conformity in which our products are used. Therefore, we appreciate confirmation of the final EMC conformity for the whole machine or equipment on your own. Wiring the Power Supply •Be sure to connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an EMC conforming dedicated noise filter 3G3AX-EFI . •Keep the ground cable as short as possible. •Keep the cable between the Inverter and the noise filter as short as possible. Connecting a Motor to the Inverter •When connecting a motor to the Inverter, be sure to use shield braided cables. •Keep the cables as short as possible. Low-voltage Directive The 3G3MX models have conformed to the EMC directive EN61800-5-1 by performing the machine installation and wiring as shown below. •The 3G3MX models are an open type device. Be sure to install it inside the control panel. •The power supply and voltage (SELV) with reinforced or double insulation should be used for wiring to the control circuit terminals. •To satisfy requirements of the LVD (low-voltage) directive, the Inverter must be protected with a molded case circuit breaker (MCCB) in case a short-circuiting accident occurs. Be sure to install a molded case circuit breaker (MCCB) on the power supply side of the Inverter. •Use one molded case circuit breaker (MCCB) per Inverter. •Use the crimp-type terminal with an insulation sleeve to connect to the main circuit terminals. •When not using the braking resistor or braking resistor unit, connect the crimp-type terminal with an insulation sleeve to the braking resistor connection terminals (P/+2, N/-). 2-29 Chapter 3 Operation 3-1 Test Run Procedure ......................................... 3-2 3-2 Test Run Operation.......................................... 3-3 3-3 Part Names and Descriptions of the Digital Operator ............................................................ 3-8 3-4 Operation Procedure (Example: Factory Default) ........................................................................... 3-10 3-5 Keys................................................................... 3-16 3-6 Parameter Transition ....................................... 3-17 3-7 Parameter List .................................................. 3-19 3Operation WARNING Do not put on or take off the Digital Operator•control circuit terminal block•terminal block cover while the input power is being supplied. Doing so may result in a serious injury due to an electric shock. Do not remove the terminal block cover during the power supply and 5 minutes after the power shutoff. Doing so may result in a serious injury due to an electric shock. 3 Operation Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious injury due to an electric shock. Do not change wiring, mode change switches, optional devices or replace cooling fans while power is being supplied. Doing so may result in a serious injury due to an electric shock. CAUTION Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the power supply and for some time after the power shutoff. Doing so may result in a burn. Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the Inverter capacity on the power supply side. Not doing so might result in damage to property due to the short circuit of the load. Safety Information Operation and Adjustment •Be sure to confirm the permissible range of motors and machines before operation because the Inverter speed can be changed easily from low to high. •Provide a separate holding brake if necessary. Precautions for Use Error Retry Function •Do not come close to the machine when using the error retry function because the machine may abruptly start when stopped by an alarm. •Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may abruptly start. Operation Stop Command •Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when function settings are performed. •When checking a signal during the power supply and the voltage is erroneously applied to the control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal. 3-1 3-1 Test Run Procedure 3-1 Test Run Procedure Item Description Reference page Installation and Mounting Install the Inverter according to the installation conditions. 2-1 •Make sure that the installation conditions are met.

Level operation: DB operates while a signal is being input. Frequency control mode: DB operates when the frequency reaches the specified level during operation. •If DC injection braking operates at a high motor speed, an overcurrent trip (E01 to E04) or overload trip (E05) may occur. For internal DC injection braking, the following adjustment may help you avoid such a situation: Lower the DC injection braking frequency (A052).

Note that setting the DC injection braking frequency to 0.0 Hz disables internal DC injection braking. •If the DC injection braking delay time (A053) is set, the output is shut off when the frequency reaches the level set in A052 during deceleration, and free-run status arises for the specified period. DC injection braking starts after the set time elapses. •Below are edge/level operations in internal DC injection braking.

DC injection braking is activated for the set time in A055 when the output frequency reaches the set value in A052 after the RUN command (FW) is turned off. Even if the RUN command is turned on during DC injection braking, the latter is effective during the set time in A055. (Example 5-a), (Example 6-a) Level operation: Giving priority to the RUN command, shifts to normal operation, ignoring the DC injection braking time (A055). If the RUN command is turned on during DC injection braking, returns to normal operation, ignoring the set time in A055.

Overload Limit •The Inverter monitors the motor current during acceleration or constant speed operation. If it reaches the overload limit level, the output frequency is lowered automatically according to the overload limit parameter. •This function prevents an overcurrent trip caused by inertia moment during acceleration, or caused by rapid load fluctuations during constant speed operation. •The overload limit level sets a current value for this function to work. •When this function operates, the acceleration time becomes longer than the set time. •With the overload limit parameter set too low, an overvoltage trip may occur due to regenerative energy from the motor. This is because of automatic deceleration from this function even during acceleration. •Make the following adjustments if this function operates during acceleration and the frequency doesn't reach the target level. • Increase the acceleration time. • Increase the torque boost. • Increase the overload limit level. • Use a higher rank Inverter. 4-29 4-2 Function Mode Overload limit level b022 Deceleration set by the overload limit parameter Output current Maximum frequency A004/A204 Target frequency F001 Inverter output frequency b023 4 Overload Warning n Overload limit level b022 Overload warning level C041 Output current OL Soft Lock Function Use this function to prohibit writing of each parameter.

Description To Save the Change to the Holding Register (Enter Command) Even if using the command to write into the holding register (06h) or into the consecutive holding registers (10h), no change can be saved in the Inverter's memory element. If the Inverter power shuts off without saving any changes, the holding register returns to the status before the changes were made. To save the holding register changes in the Inverter's memory element, the "Enter Command" must be issued according to the following procedure. To issue the Enter command: Write into all memory write (holding register number 0900h) using the writing command into the holding register (06h). In this case, a random value can be written into the holding register. Notes: •The Enter command needs considerable time. Monitor the data writing signal (coil number 001Ah) to check whether the data is being written. •Since the Inverter's memory element has a limit on the number of rewrites (approx. 100,000 times), the Inverter life may be shortened if enter commands are frequently used. 4-75 4-2 Function Mode Register Number List R/W in the list shows whether the coil or holding register accepts reading and/or writing.

Financial. If the financial position of Buyer at any time becomes unsatisfactory to Omron, Omron reserves the right to stop shipments or require satisfactory security or payment in advance. If Buyer fails to make payment or otherwise comply with these Terms or any related agreement, Omron may (without liability and in addition to other remedies) cancel any unshipped portion of Products sold hereunder and stop any Products in transit until Buyer pays all amounts, including amounts payable hereunder, whether or not then due, which are owing to it by Buyer.

Certain Precautions on Specifications and Use 1. Suitability of Use. Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases but the following is a non-exhaustive list of applications for which particular attention must be given: (i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document. (ii) Use in consumer products or any use in significant quantities. (iii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations. (iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product. NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO 2. 3. 4. 5. ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM. Programmable Products. Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof. Performance Data. Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability. Change in Specifications. Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product. Errors and Omissions. Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
