Variable Torque AC Drive. Specifically designed for medium and high horsepower fan and pump applications. Offering an adjustable V/F curve and automatic voltage regulation. The VFD-F series drive offers the capability of connecting four motors at the same time and running them consecutively. A set of motors consisting of 1 variable-speed motor and 3 constant-speed motors is allowable.

Features                

• Output frequency from 0.1~120Hz

• Adjustable V/F curve, square and cube curve

• Automatic torque boost and slip compensation

• 8 step preset speed control and 7 step PLC operation

• Built in PID feedback control with sleep/wake function

• 2 sets acceleration/de acceleration time selections, independent accel/decel S curve settings

• Built in communication interface RS-485 Modbus (RJ11)

• Master/Auxiliary and 1st/2nd frequency command source selection

• Optional relay card max 4 motors can be connected for constant pressure or circularity control

• Detachable Keypad
