Summary of Contents for Delta Electronics VFD S 115V Series

  • Page 4: Preface

    Preface Thank you for choosing DELTA’s high-performance VFD-S Series. The VFD-S Series is manufactured with high-quality components and materials and incorporate the latest microprocessor technology available. This manual is to be used for the installation, parameter setting, troubleshooting, and daily maintenance of the AC motor drive.
  • Page 5 WARNING! DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor drive is easily damaged by high-pressure. There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

In order to retain the warranty coverage, the AC motor drive should be stored properly when it is not to be used for an extended period of time.
  • Page 14 Chapter 1 Introduction|VFD-S Series If the AC motor drive is stored for more than 3 months, the temperature should not be higher than 30 °C. Storage longer than one year is not recommended, it could result in the degradation of the electrolytic capacitors. When the AC motor drive is not used for a long time after installation on building sites or places with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.

    Chapter 8 Maintenance and Inspections Modern AC motor drives are based on solid-state electronics technology. Preventive maintenance is required to keep the AC motor drive in its optimal condition, and to ensure a long life. It is recommended to have a qualified technician perform a check-up of the AC motor drive regularly. Daily Inspection: Basic check-up items to detect if there were any abnormalities during operation are: Whether the motors are operating as expected.

  • Page 163 Appendix B Accessories|VFD-S Series The length of motor cable When motor is driven by an AC motor drive of PWM type, the motor terminals will experience surge voltages easily due to components conversion of AC motor drive and cable capacitance. When the motor cable is very long (especially for the 460V series), surge voltages may reduce insulation quality.

  • Page 164: Dimensions

    Appendix B Accessories|VFD-S Series If the length is too long, the stray capacitance between cables will increase and may cause leakage current. It will activate the protection of over current, increase leakage current or not insure the correction of current display. The worst case is that AC motor drive may damage.
