Summary of Contents for Delta Electronics VFD-M Series

  • Page 4: Preface

    AC motor drive is to be installed. Refer to the Basic Wiring Diagram. VFD-M series is used only to control variable speed of 3-phase induction motors, NOT for 1- phase motors or other purpose.
  • Page 5 WARNING! DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage. 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.

If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and motor maybe damaged.
  • Page 167 Appendix CHow to Select the Right AC Motor Drive| C.1 Capacity Formulas 1. When one AC motor drive operates one motor The starting capacity should be less than 1.5x rated capacity of AC motor drive The starting capacity= ⎛ ⎞ ×...
  • Page 168 Appendix CHow to Select the Right AC Motor Drive| 2.3 When it is running continuously The requirement of load capacity should be less than the capacity of AC motor drive(kVA) The requirement of load capacity= × ≤ capacity motor drive η...
  • Page 169 Appendix CHow to Select the Right AC Motor Drive| C.2 General Precaution Selection Note 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.
  • Page 170 Appendix CHow to Select the Right AC Motor Drive| 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.
  • Page 171 Appendix CHow to Select the Right AC Motor Drive| 7、 Motor torque characteristics vary when an AC Motor Drive instead of commercial power supply drives the motor. Check the load torque characteristics of the machine to be connected. 8、 Because of the high carrier frequency PWM control of the VFD series, pay attention to the following motor vibration problems: Resonant mechanical vibration: anti-vibration (damping) rubbers should be used to mount equipment that runs at varying speed.
  • Page 172 Appendix CHow to Select the Right AC Motor Drive| the AC motor drive operates more than one motor, please pay attention to starting and changing the motor. Power Transmission Mechanism Pay attention to reduced lubrication when operating gear reduction motors, gearboxes, belts and chains, etc.
