- 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:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
- 4 volts too little, at least tens of volts
- Q:Siemens g120 inverter torque limit what is the meaning
- Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
- Q:ASUS and dell notebook power adapter can be universal?
- One, not necessarily interchangeable. Need to compare the two adapter specifications to determine:
1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute.
2, however, some foreign imports of products using 110V AC products, be careful to see clearly.
3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter;
Second, for example:
1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W;
2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
- Q:What are the AC motor speed control methods? What are the characteristics of each
- 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
- Q:How is the notebook with a power adapter?
- The safest option is to choose the same type of notebook power adapter. When in some cases (the original adapter is too expensive or not available), you can select the operating parameters and output connectors and the original adapter.
- Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- Then the motor nameplate on the standard 2P, it must be 2-pole motor, synchronous speed = 60 seconds x frequency (mainland 50Hz) / pole pairs, you can also look at the rated motor speed, about 2940 rev / 60s, so the inverter Set the number of motor poles, is set 2 pole, I hope you can be satisfied.
- Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
- Can be transferred to the rated frequency of 2 times, but to filter the mechanical characteristics of the motor and motor running time, to filter into the motor fever.
- Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
- I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,
