With the ever-mounting quality of automation control in the market, our clients demand higher levels of efficiency and accuracy for their automation equipment. The applications of their equipment become more and more specialized and diverse in response to the competitions from the market. Therefore, they start to ask for better quality of the automation components.

Delta launched VFD-VE series AC motor drive in March, 2007. VFD-VE series is the general purpose AC motor drive well-designed for the high-end equipment in the automation industry, particularly suitable for applying in elevators, hoists, all kinds of CNC equipment, plastic production lines and printing equipment.

VFD-VE series have various control modes for different demands, e.g. V/f, V/f PG, SVC (sensorless vector control), FOC PG (field oriented control) and torque control. In addition, with a PG card, VFD-VE is able to perform zero servo and multiple-point positioning. The double rated CT (constant torque)/VT (variable torque) mode can automatically upgrade the power range on the application of variable torque, e.g. blower, water pump, centrifuge and fan, saving not only your cost but also the energy.

In terms of performance, VFD-VE is very accurate in control, e.g. V/f control 1: 10, SVC control 1: 100, FOC PG control 1:1,000 and the speed accuracy can reach +0.02%. At zero servo, VFD-VE is able to output 150% holding torque. Even under SVC control and with an output frequency of 0.5Hz, VFD-VE is able to produce 150% output torque. With these features, VFD-VE will be able to satisfy all kinds of your application demands.

VFD-VE series AC motor drives are certificated by UL and CE. The power consumption 230V from 1HP ~ 50HP, 460V from 1HP ~ 100HP. The models below 10HP are built-in with a braking chopper; the models above 15HP are built-in with DC reactor, digital keypad and Modbus communication interface. The Windows PC software offers many functions including easy reading and writing of all parameters, a monitor window to view all real time measurements such as Output current, Output Frequency, Output voltage, etc., Scope function allowing users to capture peak loads and store the data for further analysis and drive tuning.

The launch of VFD-VE series is in response to the changed applications in the high-end market. Delta will continue to pursue high quality and cost effectiveness, offering wider automation applications for the industry.
