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

Chapter 2 Installation and Wiring|VFD-S Series 2.4 Wiring After removing the front cover, check if the power and control terminals are clear of debris. Be sure to observe the following precautions when wiring. General Wiring Information Applicable Codes All VFD-S series are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters Laboratories (cUL) listed, and therefore comply with the requirements of the National Electrical Code (NEC) and the Canadian Electrical Code (CEC).
Chapter 2 Installation and Wiring|VFD-S Series 2.4.1 Basic Wiring Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply may result in damage to the equipment. The voltage and current should lie within the range as indicated on the nameplate. Check the following items after completing the wiring: 1. Are all connections correct? 2. No loose wires? 3.

Chapter 2 Installation and Wiring|VFD-S 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.

When connecting a relay to the digital outputs, connect a surge absorber or fly-back diode across the coil and check the polarity. General Keep control wiring as far as possible from the power wiring and in separate conduits to avoid interference. If necessary let them cross only at 90º angle.

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/T1, V/T2, W/T3 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. Verify that no other equipment is connected to the AC motor.
Chapter 3 Start Up| VFD-S Series 3.2 Operation Method Refer to 4.2 How to operate the digital keypad and chapter 5 parameters for setting. Please choose a suitable method depending on application and operation rule. The operation is usually done as shown in the following table. Operation Method Operation Command Source Frequency Source Keypad RUN MI2 MI3 Operate from external signal GND Parameter setting: 4-05=10 4-06=11 STOP/RESET External terminals input: M0-GND M1-GND AVI, ACI 3.
Chapter 3 Start Up| VFD-S 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/T1, V/T2, W/T3 when power is still applied to R/L1, S/L2, T/L3 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.

Appendix B Accessories|VFD-S Series 1. 2. Use the cable with shielding (double shielding is the best). The shielding on both ends of the motor cable should be grounded with the minimum length and maximum contact area. 3. Remove any paint on metal saddle for good ground contact with the plate and shielding. Remove any paint on metal saddle for good ground contact with the plate and shielding.
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. To prevent this situation, please follow the rules below: Use a motor with enhanced insulation.
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. If more than one motor is connected to the AC motor drive, the total wiring length is the sum of the wiring length from AC motor drive to each motor. B.2.

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 and the performance. If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and it may be damaged. If the capacity of AC motor drive is too small, it cannot offer the required performance and the AC motor drive may be damaged due to overloading.

When the AC Motor Drive is connected directly to a large-capacity power transformer (600kVA or above) or when phase lead capacitors are switched, excess peak currents may occur in the power input circuit and the rectifier section might 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. B.
