    Warnings CAUTION Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.

    Acceleration and Deceleration Characteristics This section explains the acceleration and deceleration characteristics of the Inverter. Setting Acceleration and Deceleration Times Acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum out- put frequency (E1-04). Deceleration time indicates the time to decrease the output frequency from 100% to 0% of (E1-04).

    Troubleshooting If the Motor Rotates Even When Inverter Output is Stopped If the motor coasts at low speed after a deceleration to stop has been executed, it means that the DC injection braking is not decelerating enough. Adjust the DC injection braking as follows: Increase the constant b2-02 (DC Injection Braking Current) setting.

    Inverter Application Precautions Installation Observe the following precautions when installing an Inverter. Installation in Enclosures Either install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, 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 279: 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 control sequences carefully. Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.

  • Page 280: Motor Application Precautions

    Installation Withstand Voltage If the input voltage is high (480 V or higher) or the wiring distance is long, the motor insulation voltage must be considered. Contact your Yaskawa representative for details. Noise Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the motor is operated with a commercial power supply.

    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 an appropriate Inverter according to the maximum input current of the motor. Submersible Motor The rated input current of submersible motors is higher than that of standard motors.
