Page 50: 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 wiring the main circuit power supply inputs. 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 51 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.
Page 52 Incorrect Noise Filter Installation • Power supply MCCB Inverter MCCB General- Other purpose controllers noise filter Power MCCB supply General- Inverter purpose noise filter MCCB Other controllers Do not use general-purpose noise filters. No general- purpose noise filter can effectively suppress noise generated from the Inverter.
Page 53 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 54: Ground Wiring
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.

Suppressing Overshoot If overshoot occurs, reduce derivative time (D), and increase integral time (I). Response Before adjustment After adjustment Time Set a Rapidly Stabilizing Control Condition To rapidly stabilize the control even if overshoot occurs, reduce integral time (I), and lengthen derivative time (D).
Page 309 Suppressing Short Cycle Vibration If vibration occurs when the vibration cycle is short, and the cycle is almost identical to the derivative time (D) set value, the differential operation is too strong. Shorten the derivative time (D) to suppress the vibration. If vibration continues even when the derivative time (D) is set to 0.00 (D control disabled), reduce the propor- tional gain (P), or increase the PID primary delay time constant.

Page 334: Fine Adjustments
Individual Functions Speed Control (ASR) Gain Adjustment for 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 335 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 336 Individual Functions 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 337 Precautions for Open-loop Vector 2 Control (PRG: 102 only) The ASR primary delay time setting for open-loop vector 2 control is divided between constants C5-06 • and C5-10. The constant that is used depends on the size of the operating frequency. If the operating fre- quency is between 0 and 35 Hz, adjust the setting using C5-06, and if the operating frequency is greater than 35 Hz, adjust the setting using C5-10.

Page 394: If Constant Constants Cannot Be Set
Troubleshooting Troubleshooting Due to constant 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 395: 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, it will remain in ready status and will not start. Press the Menu Key to dis- play the drive mode, and enter the drive mode by pressing the DATA/ENTER Key.
Page 396 Troubleshooting The operation method selection is wrong. If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an exter- nal 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 397: If The Direction Of The Motor Rotation Is Reversed
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 435: Inverter Application Precautions
Applications with repetitive loads (cranes, elevators, presses, washing machines, etc.) using Inverters require derating for the repetitive load [reducing carrier frequency and current (changing accel/decel timing, increas- ing the frame size of the Inverter)]. Contact your Yaskawa representative for details. Initial Torque The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the Inverter that is driving the motor.
Page 436: Dc Injection Braking
Inverter Application Precautions Options Terminals B1, B2, 3 are for connecting only the options specifically provided by Yaskawa. 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, air-bourne matter, dust, and other contam- inants, or install the Inverter in a completely enclosed panel.
Page 437: Setting The Power Supply Voltage Jumper (400 V Class Inverters Of 55 Kw Or Higher)
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 wring 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 438: 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 Yaskawa. If 100% torque is required continuously at low speed, consider using a special Inverter or vector motor.
Page 439: 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.
