1.Advanced vector control algorithm , combine accurate speed calculation and self learning of the motor parameter. It realize the accuracy control of motor speed and torque under no- speed sensor mode. V/F and SVC can be selected .
2.Optimized space voltage vector PWM modulation technology, has over-modulation function, high voltage-utilization, low output harmonic, and it greatly improves the motor’s stability and switching loss.
3.Good operation characteristic of low frequency, can realize 0.5HZ/150% rated torque output which under no-speed sensor mode.
4.LCD and LED double display keyboard, display digit and English , the user can operate easily.
5.Control terminal analog voltage output, current output ,digit output, impulse output, Voltage, current , impulse , communication and other multi frequency setting modes. Also can realize the overplay function for all kinds of given source, And the frequency control mode is very flexible.
6.Abundant function:automatic voltage regulation control, automatic slip Compensation, restart when power cut and so on. It can meet the demand of different clients.
7.Customization function design :program running, wobble frequency running, PID control operation , timing function ,counter function ect. can be convenient to form and meet the different industrial field demands
8.Built-in RS485 interface , compat MODEBUS communication protocol, can realize networked control.
9.Super strong protect function: Over voltage, over current , over load, under voltage, over heat , short circuit and so on , can offer more than 20 kinds failure protection function for user
3.Indoor places free from direct exposure to sunlight, dust, corrosive gas, flammable gas, oil mist, steam , drip and salt.
