Wiring Main Circuit Terminals K K K K Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. nWiring Main Circuit Inputs Observe the following precautions for the main circuit power supply input. Installing a Molded-case Circuit Breaker Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker (MCCB) suitable for the Inverter.
Page 58 Installing a Magnetic Contactor If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used. When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter, however, the regenerative braking does not work and the Inverter will coast to a stop.
Page 59 Wiring Main Circuit Terminals Incorrect Noise Filter Installation • Power 3G3RV MCCB supply Inverter MCCB General- Other purpose controllers noise filter Example: SYSMAC Power MCCB 3G3RV supply General- purpose Inverter noise filter MCCB Other Do not use general-purpose noise filters. No general- controllers purpose noise filter can effectively suppress noise generated from the Inverter.
Page 60 When using an MC to switch to a commercial power supply, stop the Inverter and motor before operating the MC. Use the speed search function if the MC is operated during operation. If measures for momentary power interrupts are required, use a delayed release MC. Installing a Thermal Overload Relay This Inverter has an electronic thermal protection function to protect the motor from overheating.
Page 61 Wiring Main Circuit Terminals Countermeasures Against Radio Interference Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box. The cable between the Inverter and the motor should be as short as possible.

Page 377: Troubleshooting
Troubleshooting Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures.
Page 378: If The Motor Does Not Operate
K K K K If the Motor Does Not Operate Use the following information if the motor does not operate. nThe motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Inverter is not in drive mode, it will remain in ready status and will not start.
Page 379 Troubleshooting The operation method selection is wrong. If parameter b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation.
Page 380: If The Direction Of The Motor Rotation Is Reversed
K K K K If the Direction of the Motor Rotation is Reversed If the motor operates in the wrong direction, the motor output wiring is faulty. When the Inverter T1(U), T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a for- ward direction when a forward run command is executed.
Page 381: If The Slip Compensation Function Has Low Speed Precision
Troubleshooting nThe analog frequency reference bias setting is wrong (the gain setting is wrong). The frequency reference bias set in parameter H3-03 is added to the frequency reference. Check to be sure that the set value is suitable. nA signal is being input to the frequency reference (current) terminal A1. When 1F (frequency reference) is set for parameter H3-09 (Multi-function Analog Input Terminal A2 Func- tion Selection), a frequency corresponding to the terminal A2 input voltage (current) is added to the frequency reference.
Page 382: If The Motor Overheats
The torque limit has been reached. When a torque limit has been set in parameters L7-01 to L7-04, no torque will be output beyond that limit. This can cause the deceleration time to be too long. Check to be sure that the value set for the torque limit is suitable.
Page 383: If There Is Noise When The Inverter Is Started Or From An Am Radio
Troubleshooting (i.e., 1,200 V for 400 V class). Be sure to use a motor with a withstand voltage between the motor phases that is greater than the maximum surge voltage. In particular, when using a 400 V class Inverter, use a special motor for Inverters.
Page 384: If The Ground Fault Interrupter Operates When The Inverter Is Run
K K K K If the Ground Fault Interrupter Operates When the Inverter Is Run The Inverter performs internal switching, so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Invert- ers).
Page 385: If The Motor Rotates Even When Inverter Output Is Stopped
Troubleshooting nOscillation and hunting are occurring with V/f control. The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting parameters C4- 02 (Torque Compensation Primary Delay Time Constant), N1-02 (Hunting Prevention Gain), and C3-02 (Slip Compensation Primary Delay Time) in order.

executed, it means that the DC injection braking is not decelerating enough. Adjust the DC injection braking as follows: • Increase the parameter b2-02 (DC Injection Braking Current) setting. • Increase the parameter b2-04 (DC Injection Braking (initial excitation) Time at Stop) setting. K K K K If 0 V Is Detected When the Fan Is Started, or the Fan Stalls Generation of 0 V (main circuit voltage) and stalling can occur if the fan is turning when it is started.
Page 387 Troubleshooting nIncorrect operation due to sneak current. The Inverter input can become indefinitely ON due to an unwanted current path in the control section output. If, in the wiring diagram shown below, the output power supply for the control section is lower than 24 VDC or the power supply is OFF, current will flow as shown by the arrows and the Inverter input will operate.

Inverter Application Precautions K K K K Installation Observe the following precautions when installing an Inverter. nInstallation in Enclosures Either install the Inverter in a clean location not subject to oil mist, airborne matter, dust, and other contami- nants, or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Inverter does not go beyond the allowable temperature.
Page 427: Handling
K K K K Handling Observe the following precautions when wiring or performing maintenance for an Inverter. nWiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check wiring for any mistakes before supplying power. Check all wiring and sequences carefully. nMagnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.
Page 428: Motor Application Precautions
Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore, the motor torque should be reduced in the low-speed range whenever using a motor not made by OMRON. If 100% torque is required continuously at low speed, consider using a special inverter or vector motor.
Page 429: Using The Inverter For Special Motors
K K K K Using the Inverter for Special Motors Observe the following precautions when using a special motor. nPole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped.
