Q:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Vibration and shock. The control cabinet equipped with frequency converter will cause bad electrical contact when subjected to mechanical vibration and shock. At this time, in addition to improving the mechanical strength of the control cabinet, away from the vibration source and shockShock source should also use shock rubber pads, fixed outside the control cabinet and internal electromagnetic switches and other parts of the vibration generated. After running for a period of time, the equipment should be inspected and maintained.
Q:What's the use of switching frequency of converter?
Meanwhile, the switching frequency of the converter is adjusted, and the power loss can be adjusted. Because the switching frequency of power loss and inverter power module IGBT is related with the increase in switching frequency inverter and increasing the power loss, this makes the efficiency drop, two is the power module heating increases, is detrimental to the operation, of course work electric converter pressure is high, the power loss also increase effect.
Q:How can I learn the converter well?
If you are engaged in maintenance or after sale, you must know the main circuit diagram of the converter, rectifier, filter, inverter. Some electronic components must know, from the main circuit is frequently such as varistors, charging resistance, pressure resistance, no sense of capacitor, filter capacitor, driving circuit of multiple optocoupler such as 2503503120316, this is referred to as the optocoupler and the role, you must know the pin. Because the maintenance process should always be to determine the quality of the device.
Q:What does a frequency converter do?
Frequency converter1. What is a frequency converter?The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.2, what is the difference between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.
Q:What's the difference between universal inverter and fan pump converter?
In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.
Q:At the base block Yaskawa inverter is what reason?
For example: when you put the inverter to stop, there will be a signal to the inverter, then the converter will base the blockade, cut off the output, the motor will no longer work; when you need a converter work, there will be a signal to the inverter, inverter will cancel the locks on the base, and the normal work,This function is only equivalent to one protection.
Q:Hello everyone, I was doing fine tuning, ask inverter carved machine always ranging from the time jump out ah?
Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.
Q:Ask, what is the ratio of frequency converter?
Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.
Q:Which brand of converter is better?
Shanghai international shipping center Yangshan deep water port project, Shanghai Pudong Airport, Shanghai Hongqiao Airport, the Three Gorges project, Gansu satellite launch center, the south to North Water Diversion, the west east gas transmission, China Petroleum group,
Q:What are the precautions for frequency converter wiring installation?
1, between the power supply and inverter, access to low-voltage circuit breaker and contactor, protection of frequency converter and easy installation and maintenance;2, frequency converter and motor are generally not allowed to access contactor;3, frequency converter generally does not need to meet the thermal relay;4, the output side of the inverter is not allowed to connect capacitors and capacitive single-phase motors.5, the surrounding pay attention to ventilation, dust-proof6, the power input line has sufficient area, the screws tighten as far as possible, but do not slip, you can refer to the specifications torque.7, connect the motor cable as short as possible, there are computer occasions, as far as possible shielded cable8, the control signal line should not parallel to the power line. If parallel must be used, the shielding line and one end of the earth will be used.9, use 485 or 232 communication to wear a magnetic ring, and use twisted pair.
