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. To guarantee safe operation of the equipment, read the following safety guidelines before connecting power to 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. ; Only the qualified technicians are allowed to install, wire and maintain AC motor drive.

Appendix B How to Select AC Motor Drive |DD Series Appendix B How to Select AC Motor Drive The choice of the right AC motor drive for the application is very important and has great influence on its lifetime. If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and motor maybe damaged. If the capacity of AC motor drive is too small, it cannot offer the required performance and the AC motor drive maybe damaged due to overloading.

Appendix B How to Select AC Motor Drive |DD Series B-2 General Precautions Drives Selection 1. When the AC Motor Drive is connected directly to a large-capacity power transformer (600kVA or above) or when a phase lead capacitor is switched, excess peak currents may occur in the power input circuit and the converter section may be damaged. To avoid this, use an AC input reactor (optional) before AC Motor Drive mains input to reduce the current and improve the input power efficiency. 2.

Appendix B How to Select AC Motor Drive |DD Series B-3 How to Choose a Suitable Motor Standard motor When using the AC Motor Drive to operate a standard 3-phase induction motor, take the following precautions: 1. The energy loss is greater than for an inverter duty motor. 2. Avoid running motor at low speed for a long time. Under this condition, the motor temperature may rise above the motor rating due to limited airflow produced by the motor’s fan. Consider external forced motor cooling. 3.

Appendix B How to Select AC Motor Drive |DD Series Special motors: 1. Pole-changing (Dahlander) motor: The rated current is differs from that of a standard motor. Please check before operation and select the capacity of the AC motor drive carefully. When changing the pole number the motor needs to be stopped first. If over current occurs during operation or regenerative voltage is too high, please let the motor free run to stop (coast). 2.
