Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try

Q:That is, some parameters of the inverter, such as torque, current, frequency, etc., are displayed on the Kingview software interface, but not through the PLC. The idea that the MODBUS protocol between SIEMENS and 200PLC has never been successful before, so that's the idea of the ABB. If it can be achieved,Is it necessary to write the script program on the Kingview, and what problems should I pay attention to when using the MODBUS protocol in Kingview software?The problem is a little bit more, I hope the experts teach me this rookie! Thank you: ABB converter supports MODBUS protocol, can be directly connected to the ModbusRTU in your choice of Kingview, device configuration, set up converter address directly in Kingview read the corresponding parameters can be

Q:What is the working principle of a three phase AC asynchronous motor inverter?: Heat dissipation: the heating of the inverter is caused by internal losses. In the frequency converter, the main part of the loss is mainly the main circuit, accounting for about 98%, and the control circuit accounts for 2%. In order to ensure the normal operation of the inverter must be reliable, we usually adopt inverter heat dissipation cooling fan; inverter fan installed inside the box body can be internal heat converter away, if the fan is not working properly, should immediately stop running the inverter; inverter power also need to fan in the control cabinet, control cabinet design to air duct reasonable, all air inlet to set dustproof net, exhaust unobstructed, avoid the formation of vortex in the cabinet, the formation of dust accumulation in a fixed position; to select the matching according to the amount of ventilation fan inverter manual, fan installation should pay attention to the problem of earthquake.

Q:Heating inverter commissioning steps: And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.

Q:What are the differences between the two quadrant and the four quadrant of the inverter?: Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)

Q:Can the motor with frequency converter directly wave the insulation?: Frequency converter with motor, is a high-power three stage tube, C, E in the output, you directly shake insulation, measuring the pressure of the transistor. So you can't measure it.

Q:How to choose frequency converter?: Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on.

Q:How to deal with the fault Yaskawa inverter GF: This problem most likely. While G7 or F7 are generally Holzer Holzer sensor, sensor due to temperature. The influence of environmental factors such as humidity, work is easy to drift, to report "GF", another reason may be: E2-01 improper setting may also reported GF fault.

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:Can a power converter be used in a motor with small power? Will it burn the motor?: Can a power converter be used in a motor with low power, depending on your load and what type of converter is it?.If it is only a common fan, water pump or light load operation, then basically no request, you can use, as long as the relevant parameters can be set.
