- Q: What is the common COM point of the PLC and the inverter? Is it positive?
- It depends on your PLC and inverter I / O is what type, the most simple can be divided into two kinds of NPN and PNP, NPN COM point is negative, PNP COM is positive.
- Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- 1,2P refers to the number of motor poles, so it is certainly even 2, if the inverter is set to determine the number of motor poles, please write 2P value, if 2P = 4, please write 4 3, look at the nameplate on the motor rated speed for how much, you can confirm the number of motor poles. (N = 60f / p) P: pole pairs
- Q: 5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
- Because the frequency converter can reach 60 Hz frequency, while the three-phase power supply is the standard 50 Hz. So the inverter can make the motor speed faster than the rated 1500 rpm. The fastest up to about 1800 turn.
- Q: Servo control system can give the inverter signal,
- Servo motor driver can give the inverter signal, with analog output to control,
- Q: My laptop can not use the power adapter, and can only use the battery, how is it ah,
- Depending on your question may be the problem that the laptop's internal lines may be short-circuited 1, you can go to the video online to find the same type of machine disassemble video and then repair their own 2, get to the maintenance of the place to get on nothing
- Q: There is no inverter comes with simple PLC programming function
- The PLC is programmed to handle digital and analog, the core of the entire control system. It can output the digital to the inverter, so that the inverter is reversing, you can output the analog to the inverter set speed, but also through the communication, direct control inverter
- Q: Inverter principle eff23
- According to the use of classification, can be divided into general-purpose inverter, high-performance dedicated inverter, high-frequency inverter, single-phase inverter and three-phase inverter. VVVF: change the voltage, change the frequency CVCF: constant voltage, constant frequency. The AC power supply used by each country, whether it is for home use or for the factory, has a voltage and frequency of 400V / 50Hz or 200V / 60Hz (50Hz), and so on. In general, a device in which an alternating current having a constant voltage and frequency is converted into a voltage or a variable frequency alternating current is referred to as a "inverter". In order to produce a variable voltage and frequency, the device first converts the alternating current of the power supply into direct current (DC). For the motor control of the inverter, both can change the voltage, but also can change the frequency. Inverter control mode
- Q: Do not the laptop directly connected to the power adapter?
- 3, the notebook internal circuit using low-voltage direct current work, if the direct use of 220V AC and its connection will burn the circuit in the low-voltage devices, which is absolutely prohibited, but also basic common sense. At the same time, its external power jack is also dedicated, and the AC outlet is different;
- Q: Can the inverter be used to control the speed of the DC motor?
- The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
- Q: Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
- Which model ah, CE alarm, it should be communication failure. CE4, it seems that should be written to the read-only address. You follow the inverter model, to the Delta website to download the corresponding manual, there are fault alarm instructions.
