About products:

Stablize the country the intersection of letter and frequency converter can apply petrochemical industry to while being very extensive, cement, pottery, central air conditioner, water supply of constant pressure, safety glass light industry and machinery, packages printing machinery, mangling apparatus, metallurgical steel, centrifuge, control of tension, wire drawing machine, numerical control lathe, textile

The products are detailed:

Specialized serial frequency converters of water pump of G7/P7 air blower

Technical feature characteristic

l The death district optimized compensates technology, export the perfect sinusoidal wave electric current wave form

l High-power and machine fiber optic communication can reach 380V, 1200KW to drive

l The software can set up 220V, 380V, 660V, 1140V voltage grade

l Practical dormancy function, apply to the control system of supplying water of constant pressure extensively

l PID feedback control algorithm optimized, the customer debugs simply and conveniently

l Two No. 4 is 20mA, 0 10V outputs signals availably

l The succession inputs and absorbs and protects the circuit, has strengthened it to the protection commutating the return circuit

l Totally independent intellectual property right, can be customized and develops according to customer’s requirement

l Electric current shake, inhibit technology, solve light year such as electrical machinery or the empty load electric current shakes the difficult problem greatly

l Many kinds of drive protect technology and lengthen IGBT life-span, has improved the fault-free running time of frequency converter

l The reliable rotational speed follows the trail of the function, can discern the rotatory electrical machinery speed and direction automatically, used for the rotatory air blower starting directly

l The available liquid crystal is operated the panel, one pair of keyboards is operated at the same time, accuse of operating (too availably to need external power) outside 100 meters of keyboards far

l Optimize the space vector control method of the voltage, two kinds of PWM ways are available, PWM way 2 can reduce IGBT temperature greatly

l Park function accurately, generally touch off and park by periodically scanning the digital input terminus son, probably need 10MS reaction speed, will cause the uncertain delay, park in G7 software the order is that one is cut offs, the precision is improved greatly to park

l RTU of standard high fault-tolerant, compatible Modbus passes through technologically and helps customers to solve the communication obstacle, apply ripely to various scenes

l Ripe high reliable high-power drives technology, unit high-power 500KW, 680KW batch are applied ripely to various scenes
AM300 common serial frequency converters
l Control method Hold the ring vector to control (SVC) , V/F control, close the the intersection of ring and vector (VC) , open and close the torque control of the ring, the position ring is controlled

l Starter torque 0.5Hz/150%( SVC) , 0HZ/180% (VC)

l Adjust speed range 1: 100 ( SVC) , 1: 1000( VC)

l Steady precision & plusmn; 0.5%( SVC)

l The software and hardware inhibits interfering with and reporting the trouble by mistake strongly, guarantee not to trip to run

l Vector VF controls: The automatic torque is promoted; The manual torque is promoted 0.1% ~ 30.0%, Very self-defining VF contours

l The automatic limit flows: Limit the electric current during operation automatically, the trouble prevents from frequently overly to flow to trip, realize and has not tripped to operate

l The vector controls and makes the big torque of low frequency to run steadily, speed sensor vector does not control excellent control performance

l Can choose LED, LCD keyboard, support one pair of keyboards to be operated at the same time

l Dual relays export, two routes of 0(4) ~20 mA ,0(2) ~It is exported that 10V analog quantity is available

l The reliable rotational speed follows the trail of the function, can discern the rotatory electrical machinery speed and direction automatically, used for the rotatory air blower starting directly

l Totally independent intellectual property right, can be customized and develops according to customer’s requirement

l Voltage grade 220V, 380V, 690V, 1140V

l Ultra high-power drives technology, the unit 380V, 680KW, and machine 1400KW

l The electric wire netting loses the electricity and does not shut down in the twinkling of an eye

l The torque is controlled and run: The end son supports the speed, torque to control the mode to switch over

l High dependability: Drive ripely reliably, protect circuit design, anti-interference to design

l Close the intersection of ring and vector control, bring speed ring, the intersection of electric current and ring, the intersection of position and ring, can make zero control while being servo

l The electrical machinery parameter is studied by oneself: Rotate, resting and study by oneself

l The automatic signal carrier is adjusted: According to the load characteristic, adjust the frequency of the signal carrier automatically

l The automatic voltage is adjusted: When the voltage of the electric wire netting is changed, can keep the output voltage invariable automatically

l Automatic energy-conservation runs: According to the load situation, optimize V/F curve automatically, realize energy-conservation runs
