Brand: Hapn – peace

Name: Ask for Kenya’s peaceful factory’s home HPVFV vector and control the frequency converter

Type: HPVFV

About products:

HPVFV vector controls the frequency converter to specially adjust the speed to design for being perfect, performance is excellent, stable and reliable

The products are detailed:

HPVFV frequency converter specially adjusts the speed to design for being perfect, performance is excellent, stable and reliable. By great power output, easy-to-use, security is high, the goal pursued as the products, have performance of controlling and multi-functional and inputting and outputting controlling etc. of tuning function, PID function, multistage speed up automatically, offer the best solution.

Main characteristic:
1.Utilize the high-performance digital signal processor, through the control algorithm optimized, can offer the control of high speed, flexibility, security for complicated transmission. Especially occasion application of suitable low rotational speed, high torsion.
2.Not merely include V/F to control, realize FOC [the intersection of magnetic field and directional vector control ], have the intersection of sense and vector control the function also ‘ Question that the improvement speed that this function can be effective varies with load) ,Reach energy-conservation through transferring to the compensation function of difference.
3.PID function and tuning the function up automatically, has better energy-conserving results at the time of the occasion of supporting etc. in order to be used in the air blower, water pump in the frequency converter.
4.The system starts or reaches while presuming the number value, passes S – curve function, can realize the steady change of the speed, thus improve the control function of load with greater inertia.
5.The device is small, compact.

Main performance parameter:

Main performance:
1.Complete protection function
Pass the intersection of electric current and protection, the intersection of overvoltage and protection, the intersection of low-voltage and protection, the intersection of frequency converter and overheated protection, overload protection, zero the intersection of preface and electric current, protect, it runs to be unusually the intersection of person who protect and many kinds of protection functions.
2.The strong torque is controlled
Make the fast torque, respond to to rapid the intersection of load and change ‘ Reach the high torque to export at a low speed)
Export 150% of the torque while starting
Not feedbacking the device, the correct torque is controlled
Do the fast torque to respond to the rapid load change
1)Change and turn towards and moderate and control 2)Stop the torque to control
3.Operate and control synchronously
4.Double to operate and control rapidly
5.PID operation control function
Built-in PID control, the built-in PID algorithm can control flow, temperature, pressure,etc. in this kind of function is mainly applied to the course and controlled, through setting value and comparison between the person who feedback to close ring, use proportion, total mark, differential function realize the intersection of variable and control. Add PID and deal with the controller in the speed controls the ring. So, outside the frequency converter, even not add PID controller and PLC, can still realize many kinds of functions. PID compensates the function, can carry on effective control to the spool tension.
6.General PID control function, support many kinds of communication procedures
Support Profibus, Modbus, RS485/232C, the intersection of CAN and coherent way, realize control, the intersection of communication and the intersection of procedure and choose, the intersection of trouble and the intersection of person who track and function.
7.Following function of the trouble
Information such as the electric current, voltage, frequency, torque among one second are kept before the fault alarm of the frequency converter.
8.The driving starts the function
Start the function after starting and losing electrical power in the twinkling of an eye to load in the decline
9.Tune the function up automatically
Use simple operation, determine the electrical machinery parameter, reflect the best control function automatically

Main parameter:
1.Input specified the intersection of voltage and grade 400V ‘ 660V, 1140V are available) ,Rated power 5.5~400kW
2.Input the range 50Hz/60Hz of the voltage frequency.
3.The speed regulates the error and is smaller than 1%
4.Allow three phases to input the voltage unbalanced intensity 3% the most largely
Can run for 60 seconds, can run for 2 seconds under 175% of the overload conditions under 5.150% of the overload conditions
6.Starter torque: There is not sense V/F that control 150% (0.5Hz)
Sense vector does not control 200% ( 0Hz)
7.Output frequency / speed: There is no sense: 0.0 300.0 [Hz ] (have no encoder)
0.0 3000.0 [Hz ] (have encoders)
Sensor: 0 8000[rpm]
8.Basis frequency: Imitate I/P: 10 resolution ratios, precision & plusmn; 0.1%,
The consulting value of panel: Resolution ratio 0.01Hz/0.1Hz
9.Accelerate time: V/F controls: -0.5 3000.0[sec]
There is no & sensor vector of sense to control: -0.00 3000.00[sec]
10.The time of moderating: V/F controls: -0.5 3000.0[sec]
There is no & sensor vector of sense to control: -0.00 3000.00[sec]

Employ the occasion:
Suitable for carrying handling facility, high-speed air-blowers, compressors, requiring the higher air blower water pump to control, park apparatus and industry use fields such as the washing machine,etc., especially occasion application of suitable low rotational speed, high torsion.
