Introduction of SVF-G7 Series High-performance Vector General-purpose Frequency Inverter

1. Voltage class: 380V

2. Range of power: 0.4KW~450KW

3. Stable and reliable Control Mode

General

SVF-G7 series VFD communicate with PC, PLC etc upper machines, and they need the support of standard expansion cards SC-EXT1-IO. And the cards supply RS485 communication interface. Between the upper user machine and frequency inverter communicate through the international standard ModBus communication, and the upper user machine as host machine, and the frequency inverter as slave machine. The communication content could be finished as follows: send operating command to frequency inverter, setting operating frequency, changing function code parameters, reading frequency inverter operation situation, monitoring parameters, fault information, function code etc.

AC Driver Variable Frequency Drive for 3 Phase

Q: 65w adapter and 90w laptop power adapter What is the difference?: 65W and 90W is mainly based on your laptop power configuration, the general integrated graphics with 65W, discrete graphics because of the need for additional power supply, so the general need 90W, of course, there are some low-power CPU, such as 25WCPU , 35W, 45W difference, these are the beginning of the manufacturer according to the notebook's power consumption count a maximum power, and then give your laptop with adapter 90W adapter can replace 65W, as long as the interface is the same, but 65W instead of 90W sometimes there may be insufficient power lead to automatic shutdown. In general, the greater the number of watts, the larger the head, because the adapter is actually a coil will be 220V into 19V, according to the power to determine the head, the larger the watt, the same 19V, then the output current will be greater

Q: Three-phase asynchronous AC motor speed control method: Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ??range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.

Q: Laptop power adapter aging: First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.

Q: Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole: Check the inverter operating power factor, straight up the motor to see if it is overheating

Q: How does the variable frequency motor output torque at very low frequencies?: Low frequency, the motor torque is relatively low, generally VF inverter performance is good or bad, the price level reflected in this time. But there is torque to enhance the function, it will not move without moving. If no load can not start, check the motor card and other mechanical problems such as whether there is a problem.

Q: Delta VFD-F frequency converter how to adjust the number of poles: Look at the 07 motor parameters, I VFD-F instructions need, then the mailbox sent

Q: Yasukawa inverter reported bb code that is the reason why the base blockade?: This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad

Q: I power adapter output current 3.25A for a 4.5A, can you use it: As long as the same voltage with the same polarity on the connector can! The The This can also increase the stability of the computer ^ _ ^, and to speed up the role of charging time, in short, will not cause a bad impact on the computer.

Q: How to make the motor speed (control speed), can not use frequency: If you use AC asynchronous motor speed control in three ways: 1 / variable speed control. By changing the motor stator pole pairs to speed, not the linear speed for the sub-file speed, the motor structure and electrical control more complex. 2 / electromagnetic speed control. Driven by the magnet magnet, the electromagnetic coil through the variable size of the DC to speed, for the linear speed, but a waste of energy 3 / frequency control. Through the inverter speed, stepless speed regulation, speed control effect is good, but one-time investment. If the DC motor speed is to change the armature or the excitation coil voltage to achieve speed. Application in the relatively high demand, a one-time investment is relatively large

Q: Quartet of the TA, TC terminals have positive and negative?: This can not be said to be positive and negative, should be called the public, TA, is the common.
