Description of  Frequency Inverter

 

CMAX  frequency  inverter is a high-quality, multi-function, low-noise variable frequency drive which is designed, developed and manufactured according to international standards. It can meet different needs of industrial conditions.The inverter applies advanced control technology of space voltage vector PWM, with functions of constant voltage control, power-off restart, dead zone compensation, automatic torque compensation, online modification parameter, high-speed impulse input, simple PLC and traverse

 

Features of Frequency Inverter

 

1).Adopts 16 bit microprocessor, sine wave PWM control

 

2).Automatic torque ascension and automatic sliding compensation function

 

3).Output frequency 0.1-400 Hz

 

4).8 period of speed setting and 7 period can be running the program

 

5).Low noise, carrier frequency can from 1 kHz-15 kHz adjustment

 

6).Two paragraphs Acceleration and deceleration time and two segments of the S Curve slow and deceleration

 

7).Simulation frequency set acceptable 0-10 VDC, 4-20 mA

 

8).The built-in serial communication interface RS-485(baud rate can reach 38400)

 

9).Save energy running and automatic voltage stabilizing section function (AVR)

 

10).Adjustable V/F curve Acceleration and automatic and deceleration function

 

11).Simple vector control and built-in PID control, and the simple positioning function

 

12).Sleep/wake up function and zero velocity keep function
