  • Page 2: 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.
  • Page 3 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.

  • Page 11: Storage

    Chapter 1 Introduction|VFD-S Series DIVISION PLATE SCREW 1.4 Storage The AC motor drive should be kept in the shipping carton or crate before installation. 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 12 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.

  • Page 36 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.

    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.

    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.
  • Page 50 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.

The shielding on both ends of the motor cable should be grounded with the minimum length and maximum contact area. 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.
  • Page 160 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.

    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 the motor needs to decelerate within a certain time with high load inertia that can’t be handled by the AC Motor Drive in the required time, either use an external brake resistor and/or brake unit, depending on the model, (to shorten deceleration time only) or increase the capacity for both the motor and the AC Motor Drive.

Motor dynamic balance and rotor endurance should be considered if the operating speed exceeds the rated speed (60Hz) of a standard motor. Motor torque characteristics vary when an AC Motor Drive instead of commercial power supply drives the motor.
