Inverter and servo drive are the most widely used driving equipment in the transmission system. When talking about the difference between the two, many people only know that inverter is often used in low-end mechanical equipment, while servo drive is mostly used in high-end mechanical equipment. This is a relatively general statement. Frequency converter is a power control device that uses the on-off function of power semiconductor devices to convert power frequency power into another frequency. It can realize the functions of soft start, frequency conversion, speed regulation, improving operation accuracy and changing power factors of AC asynchronous motor. Frequency converter can drive frequency conversion motor, common AC motor, mainly acts as the role of adjusting the motor speed. Frequency converter is usually composed of rectifier unit, intermediate circuit, inverter and controller. Servo system is an automatic control system that enables the object's position, orientation, state and other output controlled quantity to follow the arbitrary change of the input target (or a given value). The main task is to amplify, transform and regulate the power according to the requirements of the control command, so that the torque, speed and position of the output of the driving device is very flexible and convenient. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #inverter #forfrequencydrive #ACvfd #frequencyinverter #threephaseacinverter#ZJSHUYI #acdrive #motorinverter #singlephasemotorvfddrives #frequencyconverter#SHUYITOP

Maintenance requirements in the day-to-day operation of the frequency converter 1. Check whether the cooling system is normal, and clean the dust of the air filter. 2. Check whether the screws, bolts and other fasteners of the inverter are loose, and perform necessary tightening; for the parts with soldering and crimping terminals, check whether there is corrosion, discoloration, cracks, damage, etc., and also check the frame Whether the structural parts are loose, whether the conductors and wires are damaged, etc. 3. Check whether the connection of the control circuit board is loose, whether the capacitor is leaking, whether the lines on the board are rusted, broken, etc. 4. Check whether the filter capacitor is leaking and whether the capacitance is reduced. 5. Check whether the insulation resistance is within the normal range. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #VFD #INVERTER #frequencyinverter #frequencyconverter #shuyitop #converter ...

Usually the soft start system is composed of softstart device, peripheral circuit and motor load. Therefore, the objects protected by the soft start system are also the soft start device, peripheral circuit and motor load. The purpose of protecting the soft start system is to ensure the safe and reliable operation of thyristor components, #softstarter equipment and circuits, and not damage or cause safety accidents under various abnormal working conditions. The premise of #softstarter protection is that the design of the soft starter itself should be correct. The thyristor components are correct and used correctly, the drive circuit and the control circuit are reasonably designed and matched with each other, so that the device can work in a good state. These measures are the basis for the safe and reliable operation of the soft starter. Only under this premise, can the devices, circuits, and equipment fail less and not fail from the inside, and the optimized system design should aim ...

Foreword: Inverter repairers must keep in mind that the inverter module and the drive circuit are strongly related to failures. When the inverter module bursts and damages, the drive circuit is bound to be damaged by impact. The damage of the inverter module may also be caused by the failure of the drive circuit. Therefore, whether it is a failure of the drive circuit or the inverter output circuit, it must be The inverter output circuit and the drive circuit are thoroughly inspected together. The power-on test of the main circuit must be carried out under the premise that the drive circuit is normal and can output six excitation pulses normally. Inverter power failure A 132KW inverter has a black screen fault. Part of the wire drawing machine stopped in the wire drawing workshop, and restarted production after half a month. As a result, the inverter went black after being powered on. It was judged that the switching power supply was faulty on the spot. The inverter was removed, and th...
