Technical Specification

Motor Wiring

Short circuit or grounding of the variable frequency controller output terminals is prohibited. Otherwise, it will cause damage to the internal VFD Inverter Components.

Avoid output cables (U/V/W) short circuit or short circuit to enclosure, otherwise there is a risk of electric shock.

It is strictly forbidden to connect a capacitor or phase lead LC/RC noise filter to the output of the AC Converter Drive, otherwise the drive will be damaged.

When a contactor is installed between the High quality VFD and the motor, the switching action of the output contactor cannot be performed during the operation of the drive, otherwise a large current will flow into the drive to and the drive will report fault information.

Cable length between drive and motor: When the cable between the RS485 Modbus Frequency Drive and the motor is too long, the high-order harmonic leakage current at the output will adversely affect the drive and peripheral devices. It is recommended to install a output AC reactor when the motor cable exceeds 100 meters, and contact the manufacturer to inquire whether the carrier frequency needs to be modified.

Applications

VFD Electrical Electronic Engineering Representative Industry

AC drives are used to bring about process and quality improvements in industrial and commercial applications' acceleration, flow, monitoring, pressure, speed, temperature, tension, and torque. Whenever a load has either a variable torque or a variable speed, a VFD should be considered to control torque and speed. V9 series universal speed AC drive of Shenzhen V&T Technologies Co.,Ltd. is suitable for V&T Pump Drives, Printing Packaging, Petrochemical, Textile, Cable Machinery, Food Packaging, Electric Vehicles, Plastic Machinery, Metal Products Equipment, Centrifuges and High-end applications requiring closed-loop vector or torque control.
