Summary of Contents for Delta Electronics VFD-DD Series

  • Page 2 Preface Firmware Version 1.07 Thank you for choosing DELTA’s high-performance VFD-D D Series. The VFD-DD 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 3 Do NOT connect AC main power directly to the drive’s output terminals U/T1, V/T2 and W/T3. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor drive is easily damaged by high-pressure. A charge may still remain in the main circuit terminals with hazardous voltages, even when motor has come to stop.
  • Page 4 without prior notice. Please contact your local distributors or visit our website to download the most updated version at http://www.delta.com.tw/industrialautomation/. The AC motor drive may also be called as “drive”, all drive mentioned in this manual refers to the AC motor drive.
