Preface Thank you for choosing DELTA’s high-performance VFD-B Series. The VFD-B Series is manufactured with high-quality components and materials and incorporates 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 5
WARNING! 1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor drive is easily damaged by high-pressure. 2. 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. 3. Only qualified persons are allowed to install, wire and maintain AC motor drives.

Please check the chart of Appendix B and select the correct fuse with rated current. Use of an NFB is optional. Magnetic contactor (Optional) Please do not use a Magnetic contactor as the I/O switch of the AC motor drive, as it will reduce the operating life cycle of the AC drive.

Chapter 2 Installation and Wiring|VFD-B Series DO NOT connect phase-compensation capacitors or surge absorbers at the output terminals of AC motor drives. With long motor cables, high capacitive switching current peaks can cause over-current, high leakage current or lower current readout accuracy. To prevent this, the motor cable should be less than 20m for 3.7kW models and below. And the cable should be less than 50m for 5.5kW models and above. For longer motor cables use an AC output reactor.
PAGE 38
Chapter 2 Installation and Wiring|VFD-B Series WARNING! 1. Short-circuiting [B2] or [-] to [+2/B1] can damage the AC motor drive. Grounding terminals ( ) Make sure that the leads are connected correctly and the AC drive is properly grounded. (Ground resistance should not exceed 0.1Ω.) Use ground leads that comply with local regulations and keep them as short as possible. Multiple VFD-B units can be installed in one location.

Chapter 2 Installation and Wiring|VFD-B Series General Keep control wiring as far away as possible from the power wiring and in separate conduits to avoid interference. If necessary let them cross only at 90º angle. The AC motor drive control wiring should be properly installed and not touch any live power wiring or terminals. NOTE If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as possible to AC drive.

Chapter 3 Start Up 3.1 Preparations before Start-up Carefully check the following items before proceeding. Make sure that the wiring is correct. In particular, check that the output terminals U, V, W. are NOT connected to power and that the drive is well grounded. Verify that there are no short-circuits between terminals and from terminals to ground or mains power. Check for loose terminals, connectors or screws.

Chapter 3 Start Up|VFD-B Series 3.2 Operation Method Refer to 4.2 How to operate the digital keypad VFD-PU01 and chapter 5 parameters for setting. Please choose a suitable method depending on application and operation rule. The operation is usually used as shown in the following table.
PAGE 52
Chapter 3 Start Up|VFD-B Series NOTE 1. Stop running immediately if any fault occurs and refer to the troubleshooting guide for solving the problem. 2. Do NOT touch output terminals U, V, W when power is still applied to L1/R, L2/S, L3/T even when the AC motor drive has stopped. The DC-link capacitors may still be charged to hazardous voltage levels, even if the power has been turned off. 3. To avoid damage to components, do not touch them or the circuit boards with metal objects or your bare hands.

Appendix B Accessories B.1 All Brake Resistors & Brake Units Used in AC Motor Drives Note: Please only use DELTA resistors and recommended values. Other resistors and values will void Delta’s warranty. Please contact your nearest Delta representative for use of special resistors. For instance, in 460V series, 100hp/75kW, the AC motor drive needs 2 brake units with total of 16 brake resistors, so each brake unit uses 8 brake resistors.

Appendix B Accessories|VFD-B Series 8. Definition for Brake Usage ED% Explanation: The definition of the barking usage ED(%) is for assurance of enough time for the brake unit and brake resistor to dissipate away heat generated by braking. When the brake resistor heats up, the resistance would increase with temperature, and brake torque would decrease accordingly. Suggest cycle time is one minute 100% Brake Time T1 ED% = T1/T0x100(%) Cycle Time 9.

Appendix C How to Select the Right 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.

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.
