Although care has been given in documenting the product, please contact your OMRON representative if you have any suggestions on improving this manual.

The product contains potentially dangerous parts under the cover. Do not attempt to open the cover under any circumstances. Should you find any problems with the product, immediately contact your nearest local sales representative. Set screws and other necessary parts must be prepared by customers. Always turn the main circuit off before modifying wiring or checking signals.

Touching terminals while the main circuit is on may cause an electrical shock and dam- age the equipment. Therefore, constant numbers can be confirmed easily. Separate Input and Output Terminal Blocks Power input terminals are located in the upper section, while motor output terminals are in the lower section.

Page Digital Operator Chapter 2 Digital Operator Data display section Monitor item indicators In-service item indicators green indicators Display These items can be monitored or set even section during operation. Stopped item indicators red indicators These items can be set only when the Inverter is stopped. Note 1. AR 0. ABR 0. Page Ambient Temperature Control Chapter 3 Ambient Temperature Control To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature rises.

If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50 C. The surface temperature of the Inverter may reach 30 C higher than the ambient tem- perature. Constant no.

If the power supply for the main circuit is to be shut off because of the sequence, a mag- netic contactor can be used instead of a molded-case circuit breaker. Other controllers Note Use a special-purpose noise filter for Inverters.

If voltage is applied to the output terminals, the internal mechanism of the Inverter will be damaged. Never Short or Ground the Output Terminals Caution If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur.

Page 27 Chapter 3 Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller to malfunction. Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make noise.

How to Prevent Induction Noise As described above, a noise filter can be used to prevent induction noise from being generated on the output side. Page Ground Wiring Chapter 3 Cable Length between Inverter and Motor If the cable between the Inverter and the motor is long, the high-frequency leakage cur- rent will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency set in n37 as shown in the table below.

Page Wiring Control Circuit Terminals Chapter 3 Note Minimize the total length 5 m or less between the ground electrode and the ground terminal, and also use a thick wire 1. Leakage current flows through the Inverter. Therefore, if the distance between the ground elec- trode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable. Page 30 Chapter 3 Always separate the control signal line from the main circuit cables and other power cables.

Thin-slotted screwdriver Control circuit terminal block Length of stripped portion: Approx. Otherwise, faulty contact may result.

Always separate the transmission cables from the main circuit cables and other power cables. Always connect the positive terminal to the positive terminal and the negative terminal to the negative terminal. Do not connect a positive terminal to a negative terminal. Setting the Terminator Open the terminal block cover in the lower part of the Inverter. Installation: Install the Inverter according to installation conditions. Check that all the installation conditions are met.

Wiring: Connect the Inverter to power supply and peripheral devices. Select peripheral devices that meet the specifications, and wire them correctly. Set and end unit as necessary. Page 36 Chapter 4 c n31 electronic thermal reference current d n11 reference frequency Test Run: Check motor operation. Use the Digital Operator to check motor operation. Perform a no-load test run and an actual loading test run to check the direction of motor rotation, speed, and output cur- rent.

Page Function Of Each Component Chapter 4 Function of Each Component Display Sections Data display section Reference frequency values, output frequency values, output current values, constant settings, and error codes are displayed. Monitor item indicators When this indicator is lit, an output frequency value Hz is displayed in the data display section.

During operation, only the items in the in-service item indicators section can be monitored and the constants for these items can be set. When the Inverter is stopped, all items can be monitored and the constant for each item can be set. Example Indi- Description of data cator display Output frequency Page Monitor Display Chapter 4 Monitor Display The 3G3EV allows the user to monitor the reference frequency, output fre- quency, output current, and the direction of rotation.

The constants for basic operations are allocated to dedicated indicators, so the user need not refer to the constant nos. The constants allocated to dedicated indicators can be also set by lighting the PRGM indicator. Press the Increment Key. Value Description Deceleration stop Page Carrier Frequency Chapter 4 Note 2. Page 54 Chapter 4 Note As the cable between the Inverter and the motor becomes longer, a high-frequen- cy leakage current from the cable increases, causing the Inverter output current to increase as well.

This may also affect peripheral devices. To prevent this, ad- just the carrier frequency according to the following standards: Cable length of 50 meters or less: 10 kHz or less Cable length of 50 to meters: 5 kHz or less Page 56 Chapter 4 Error code Description Error category n50 is used to specify whether over-torque is to be monitored and specify the action to be taken when over-torque is detected.

Set the word address in constant no. Base no. RM address Allocated to Word no. Page 60 Chapter 4 Word no. Page 62 Chapter 4 Setting Override Data If 0 is set in n06 multi-function input selection 1 , bits 4 to 7 are used to set override data. Output frequency can be set in terms of the percentage of the value set in n18 fre- quency reference 8. First, start the motor through the Digital Operator without connecting the motor to the mechanical system. Next, connect the motor to the mechanical sys- tem and perform a test run.

The RUN, ALARM, and transmission indicators on the front panel indicate the current Inverter status, and the data display section also displays information about an error that has occurred. These functions therefore enable the user to take the appropriate actions to correct most errors. The data display section also flashes.

When warning status arises, no error code is output. Eliminating the cause recovers the system automatically. Data Description Action The acceleration and deceleration time settings are too short.

A special motor is used. The radiation fin overheated because Reduce the load. Reset constant Nos. Howev- er, all indicators are not lit when a control circuit error occurs. If an Inverter error occurs, turn the power off, then on. Page Troubleshooting Chapter 5 Troubleshooting If the Inverter or motor does not operate properly when the system is started, constant settings or wiring may be incorrect. In this case, take the appropriate action as described below. If an error code is displayed, refer to Protective and Diagnostic Functions.

After cor- recting the unit number, turn the power off, then on. Motor capacity should be also increased. If terminals U, V, and W on the Inverter are correctly connected to terminals U, V, and W on the motor, the motor rotates in the forward direction when a forward rotation com- mand is input. Modify the sequence so that brakes are applied when the Inverter enters DC braking status.

Take the following actions to prevent noise: Reduce the carrier frequency of the Inverter. The number of internal switching times is reduced, so noise can be reduced to some extent.
