  • Page 48: 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/L1, S/L2, and T/L3) and power supply via a molded-case circuit breaker (MCCB) suitable for the Drive.
  • Page 49 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 Drive, however, the regenerative braking does not work and the Drive will coast to a stop.
  • Page 50 Incorrect Noise Filter Installation • Power supply MCCB Drive MCCB General- Other purpose controllers noise filter Power MCCB supply General- Drive purpose noise filter MCCB Other controllers Do not use general-purpose noise filters. General- purpose noise filter can not effectively suppress noise generated from the Drive.
  • Page 51 Wiring Main Circuit Terminals Do Not Use an Electromagnetic Switch Never connect an electromagnetic switch (MC) between the Drive and motor and turn it ON or OFF during operation. If the MC is turned ON while the Drive is operating, a large inrush current will be created and the overcurrent protection in the Drive will operate.
  • Page 52 Countermeasures Against Radio Interference Radio noise is generated from the Drive 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 Drive in a totally enclosed steel box. The cable between the Drive and the motor should be as short as possible.

    Installation Observe the following precautions when installing Drive. Installation in Enclosures Either install the Drive in a clean location not subject to oil mist, airborne matter, dust, and other contaminants, or install the Drive in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Drive does not go beyond the allowable temperature.

  • Page 433: Handling

    Drive Application Precautions Handling Observe the following precautions when wiring or performing maintenance for Drive. Wiring Check The Drive will be internally damaged if the power supply voltage is applied to output terminal U/T1, V/T2, or . Check wring for any mistakes before supplying power. Check all wiring and sequences carefully. W/T3 Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.

  • Page 434: 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 drive or vector motor.

  • Page 435: Using The Drive For Special Motors

    Motor Application Precautions Using the Drive 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 Drive according to the maximum input current of the motor to be used. Before changing the num- ber of poles, always make sure that the motor has stopped.
