Selection and technical parameters of Huichuan frequency converter MD310 series

1. Compact structure
Small size, high cost-effectiveness. Multiple units can be installed in parallel, saving space.

2. High starting torque performance
Full load speed and torque test: motor output rated torque of 102.4Nm at full load; SVC control speed fluctuation measured at 0.2%; SVC control stable speed accuracy measured at 0.4%.

3. Instant stop function
This function means that the frequency converter will not stop during an instantaneous power outage. In the event of a sudden power outage or voltage drop, the frequency converter reduces its output speed and compensates for the voltage drop by feeding back energy through the load, in order to maintain the short-term operation of the frequency converter.

4. Perfect braking function
The overexcitation function can effectively suppress the rise of bus voltage during deceleration and avoid frequent overvoltage faults.

5. Built in PID function
Built in PID regulator, combined with the selection of frequency given channels, users can easily achieve automatic adjustment of process control, realizing control applications such as constant temperature, constant pressure, tension, etc.

6. Swing frequency function
In textile and chemical fiber processing equipment, the use of swing frequency function can improve the uniformity and density of yarn spindle winding.

7. Multi motor switching function
It can store 4 sets of motor parameters, and one frequency converter can control the operation of four motors in a time-sharing manner.

8. Timer control function
Timer operation function, the running time can be set through parameters and analog quantities.

9. Support multiple fieldbus options
The standard RS485 communication interface supports Modbus RTU communication and can be extended to CANopen and CANlink, enabling fast bus connection with Huichuan products.

10. Powerful backend software
Support frequency converter parameter operation and virtual oscilloscope function. Visual monitoring of the internal status of the frequency converter can be achieved through a virtual oscilloscope.

11. Equipped with input phase loss protection, motor to ground short circuit and motor to phase short circuit protection functions
More reliable operation is guaranteed.

12. Full range standard configuration with built-in brake unit
Standard brake unit, users can directly connect the brake resistor without external braking, saving costs.
