Page 56: Wiring The Main Circuits
Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. Wiring 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 57 Wiring Main Circuit Terminals 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.

No general- controllers purpose noise filter can effectively suppress noise generated from the Inverter.
Page 59 Wiring Main Circuit Terminals 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.
Page 60 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 254: Compensating For Insufficient Torque At Startup And Low-Speed Operation (Torque Compensation)
Compensating for Insufficient Torque at Startup and Low-speed Opera- tion (Torque Compensation) The torque compensation function detects that the motor load has increased, and increases the output torque. V/f control calculates and adjusts the motor primary loss voltage according to the output voltage (V), and compensates for insufficient torque at startup and during low-speed operation.
Page 255 Improved Operating Efficiency Adjusting Torque Compensation Gain Normally, there is no need to make this adjustment. Do not adjust the torque compensation gain when using open-loop vector control. Adjust the torque compensation gain using V/f control in the following circumstances. If the cable is very long, increase the set value.

Page 380 Speed Control (ASR) Gain Adjustment for Flux Vector Control Use the following procedure to adjust C5-01 and C5-03 with the mechanical system and actual load con- nected. At zero-speed, increase C5-01 (ASR P Gain 1) until there is no oscillation. At zero-speed, decrease C5-02 (ASR I Time 1) until there is no oscillation.
Page 381 Individual Functions Adjusting ASR Proportional Gain 1 (C5-01) This gain setting adjusts the responsiveness of the speed control (ASR). The responsiveness is increased when this setting is increased. Usually this setting is higher for larger loads. Oscillation will occur if this setting is increased too much.
Page 382 Different Gain Settings for Low-speed and High-speed Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the mechanical system at low speed or high speed. The proportional gain P and integral time I can be switched according to the motor speed, as shown below.
Page 383 Individual Functions Gain Adjustment for Speed Control during V/f Control with PG When using V/f control with PG, set the proportional gain (P) and the integral time (I) at E1-09 (minimum out- put frequency) and E1-04 (maximum output frequency). Fig 6.90 Speed Control Gain Integral Time Adjust- ment for V/f Control with PG shows how the proportional gain and integral time change in linear fashion based on the speed.
Page 384: Increasing The Speed Reference Response (Feed Forward Control)
Increasing the Speed Reference Response (Feed Forward Control) Use feed forward control to increase the responsiveness to speed references. This function is effective for machines for which the ASR gain cannot be increased to a large value because doing so would result in vibra- tions.

Page 439: 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 440: If The Motor Does Not Operate
If the Motor Does Not Operate Use the following information if the motor does not operate. The 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 and the DRIVE indicator on the Digital Operator (JVOP-161) does not light up, the Inverter will remain in ready status and will not start.
Page 441 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 442: If The Direction Of The Motor Rotation Is Reversed
The motor only rotates in one direction. "Reverse run prohibited" is selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run pro- hibited), the Inverter will not receive Reverse Run Commands. To use both forward and reverse operation, set b1-04 to 0.
Page 443: If The Motor Operates Higher Than The Reference
Troubleshooting If the Motor Operates Higher Than the Reference Use the following information if the motor operates higher than the reference. The 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.
Page 444: If The Motor Overheats
The deceleration time setting is too long. Check the deceleration time setting (parameters C1-02, C1-04, C1-06, and C1-08). Motor torque is insufficient. If the parameters are correct and there is no overvoltage fault, then the motor's power is limited. Consider increasing the motor capacity.
Page 445: If There Is Noise When The Inverter Is Started Or From An Am Radio
Troubleshooting The ambient temperature is too high. The motor rating is determined within a particular ambient operating temperature range. The motor will burn out if it is run continuously at the rated torque in an environment in which the maximum ambient operating temperature is exceeded.
Page 446 There may be resonance between the mechanical system's characteristic frequency and the carrier frequency. If the motor is running with no problems and the machinery is oscillating with a high-pitched whine, it may indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency with parameters C6-02 to C6-05.
Page 447: If The Torque Generated For The Motor Is Insufficient (Insufficient Power)
Troubleshooting PID control diverges. The following causes are possible. Feedback is not being input. If no feedback is being input and the detection value is zero, PID control will fail to function and the output will diverge. This will cause the motor speed to increase to the maximum frequency. Check for a break in the feedback signal or for an incorrect setting of either H3-09 (multi-function analog input terminal A2 function selection) = B or H6-01 (pulse train input function selection) = 1.
Page 448: If Ov Is Detected When The Fan Is Started, Or Fan Stalls
If OV is Detected When the Fan is Started, or Fan Stalls Generation of OV (main circuit voltage) and stalling can occur if the fan is turning when it is started. The DC injection braking is insufficient when starting. This can be prevented by slowing fan rotation by DC injection braking before starting the fan. Increase the parameter b2-03 (DC injection braking time (initial excitation) at start) setting.

Page 509: Inverter Application Precautions
Inverter Application Precautions This section provides precautions for selecting, installing, setting, and handling Inverters. Selection Observe the following precautions in selecting an Inverter. Installing Reactors A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a phase capacitor.
Page 510: Installation
Inverter Application Precautions Options Terminals B1, B2, 3 are for connecting only the options specifically provided by OMRON. Never connect any other devices to these terminals. Installation Observe the following precautions when installing an Inverter. Installation 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.
Page 511: Handling
Handling Observe the following precautions when wiring or performing maintenance for an Inverter. Wiring 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. Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.
Page 512: 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 513: Using The Inverter For Special Motors
Using the Inverter for Special Motors Observe the following precautions when using a special motor. Pole-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.
Page 514: Conformance To Ul Standard
Conformance to UL Standard Conformance to UL Standard To comply with UL standard, follow the appropriate installation instructions.
