Summary of Contents for Delta Electronics AC Motor Drive VFD-G

  • Page 4: Chapter 5 Troubleshooting

    The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and W/T3 directly to the AC mains circuit power supply. Ground the VFD-G using the ground terminal. The grounding method must comply with the laws of the country where the AC motor drive is to be installed.
  • Page 5 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.

    After removing the front cover, check if the power and control terminals are clear. Be sure to observe the following precautions when wiring. General Wiring Information Applicable Codes All VFD-G 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).
  • Page 25 Users must connect wires according to the circuit diagrams on the following pages. Do not plug a modem or telephone line to the RS-485 communication port or permanent damage may result. Pins 1 & 2 are the power supply for the optional copy keypad only and should not be used for RS-485 communication.

  • Page 29 Chapter 2 Installation and Wiring| 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.

  • Page 32 CAUTION! Mains power terminals (R/L1, S/L2, T/L3) Connect these terminals (R/L1, S/L2, T/L3) via a non-fuse breaker or earth leakage breaker to 3- phase AC power (some models to 1-phase AC power) for circuit protection. It is unnecessary to consider phase-sequence. It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off power quickly and reduce malfunction when activating the protection function of AC motor drives.
  • Page 33 Chapter 2 Installation and Wiring| To improve the power factor and reduce harmonics, connect a DC reactor between terminals [+1, +2(+2/B1)]. Please remove the jumper before connecting the DC reactor. Models of 18.5kW~160kW have a built-in DC reactor; models of 185kW~220kW have a built-in AC reactor.

    If the stall prevention function is activated, the accel./decel. time is automatically extended to a length that the AC Motor Drive can handle. 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.
  • Page 181 Appendix C How to Select the Right AC Motor Drive| 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. 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 182 Synchronous motor: The rated current and starting current are higher than for standard motors. Please check before operation and choose the capacity of the AC motor drive carefully.
