Q:What is the difference between frequency converter and servo driver?: The general use of the situation, such as high-speed, high-precision positioning equipment, servo, high power speed control using frequency conversion.Like the central air conditioning system, elevators and so on, many places use frequency conversion; like the textile machine, the placement machine, the plug-in machine uses the servo. In fact, many cases are used in conjunction with the two systems, according to the needs of the design arrangements.

Q:What are the key points of frequency converter maintenance?: Frequency converter routine maintenance and repair workDo a good job of frequency converter routine maintenance and repair work, including:(1) regular (three months) of dust on the inverter, the focus is the electrical control cabinet, inverter inverter main base, terminal block, inverter air inlet and outlet is dust or because of too much dust and jam. Frequency converter because of its cooling requirements, ventilation volume, so after running a certain period of time, the surface dust is very serious, must be regularly cleaning dust.(2) to drive the front door open, carefully check the AC and DC bus has no deformation, corrosion, oxidation, busbar connection screws are loose, the fixed point solid screws are loose, fixed with insulating piece or insulation column aging or cracking deformation, such as a replacement, and when fastening, on bus has been deformed to be re installed after correction.

Q:What is the main function of the frequency converter on the machine tools?: CNC machine tool spindle drive system is also called the main transmission system, is to complete the main movement of the power unit part. The main shaft drive system is changed into the cutting moment and cutting speed of the tool or workpiece installed on the main shaft by the transmission mechanism, and the ideal parts are matched with the feed movement. It is one of the forming movement of parts processing, and its accuracy has a great influence on the machining accuracy of parts. Machine tool spindle drive and the drive is different, the machine spindle motion is usually rotation, unlike feed drive need wire rod or other linear motion device for reciprocating motion, NC cutter and workpiece by rotating the spindle and feed the cutting motion.

Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?: The reverse brake has one of the biggest disadvantages: when the motor speed is 0, if the power supply is not removed in time, the motor will reverse. There are two methods to solve this problem: 1, in the control loop of the motor power supply phase, adding a time relay, when the brake after a period of time, disconnect the power after inversion, so as to avoid motor reversal. But the braking time is difficult to estimate because of this method, so the braking effect is not accurate. 2. A speed relay is added to the control circuit of the motor's inverting power supply. When the sensor detects the speed of the motor is 0, the inverter power of the motor is cut off in time. Because of this method, the speed relay monitors the motor speed in real time, so the braking effect is much better than the last one. It is precisely because reverse braking has this characteristic, therefore, it is not allowed to reverse the machinery, such as some lathes, etc., the brake method can not use reverse braking, and can only use energy consumption braking or mechanical brake.

Q:What are the benefits of installing economizer in industrial enterprises?: Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.

Q:How can I learn the converter well?: 1. overload or acceleration and deceleration in case of braking resistance to increase, to help the loss of mechanical energy, you may have to set the corresponding parameters. 2. inverter motor with a little weak, if there is an advanced mode (magnetic flux vector control and the like), enable this function can play a maximum motor ability (the specific reference manual, cheap converter is not it) 3. serial communication change frequency, need to understand the communication protocol converter, usually have instructions to write specific parameters of frequency message reference manual.

Q:The functions of frequency converter and UPS are similar, especially the power frequency UPS?: Frequency converter: the principle is AC-DC-AC conversion, output AC amplitude, frequency adjustable, auxiliary function more, more used for AC motor frequency control, no battery;UPS: is intended as a standby power supply uninterruptible power supply, electrical equipment, usually the power is converted to DC and stored through the inverter output fixed amplitude and frequency power supply is cut off the AC power supply, with battery.

Q:Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: There are only three reasons for the POFF fault: (1) the DC bus voltage detected by the machine is seriously low. (2) lack of phase signal. (3) the voltage level parameter of 220V machine is wrong. [method] use the shift key on the keyboard or the mask to switch the display content to the display bus voltage status.

Q:What's the use of switching frequency of converter?: The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.

Q:Can the motor with frequency converter directly wave the insulation?: Is not possible because of the use of the insulating shake shake table while the output is DC but after conversion voltage value will exceed the rated voltage of the motor, the only way to test the motor winding phase to ground and insulation. But if the use of motor inverter drive, measurement of motor and inverter will not disconnect it, shake table issued a "high voltage" will be through the introduction of inverter winding inside, will lead to some components breakdown within the inverter a damaged, because although some internal components can be through the large current but the degree of pressure will be very limited so, in the insulating shake measure motor using frequency converter to the inverter and the motor is disconnected after, can make sure not to damage the transducer.
