Motor inverter key parts from Germany and Japan

Product Characteristic:

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

10. Overload capacity: Type G:150%  1 minute: 180% 1 second: 200% transient protection

                                  Type P:120%  1 minute: 150% 1 second: 180% transient protection

11.Control method: speed  sensorless  vector  control (SVC)

12.Protection funtion: Input open-phase protection,over-current protection,overload protection,undervoltage protection,overheating protection and etc.

13.Some components inside the inverter are imported from Germany and Japan . Like We used  Infineon IGBT and MITSUBISHI IGBT . and the  NICHICON and STG capacitor .
