Frequency conversion speed regulation of several special motors - Senlan frequency converter

What happens when the inverter-controlled motor presses the abort button, and the motor is not controlled to speed up? 1. If it is a newly installed inverter, it is generally necessary to consider the wiring problem, you can first change the parameters to switch to the panel control, the panel is given the frequency, and then see if the inverter operation will appear in this ...

1. Obtain accurate motor parameters from low to high parameters at different frequencies, and establish motor models of corresponding frequency bands in different frequency segments, so that the inverter can control the motor from low to high. 2. V/F control (1) It is possible to select 15 pre-set V/...

1. Phase alignment method of incremental encoder The alignment between the phase of the UVW electronic transmutation signal and the phase of the rotor pole, or the phase of the TV spot, of the incremental encoder with the signal exchange is as follows: 1) Use a DC power supply to pass the UV winding of the motor to less than the amount of ...

Poor choice This should be the situation that friends have encountered the most in the Z, the situation of large horse-drawn carts and small horse-drawn carts is everywhere. The big horse-drawn trolley is not bad, at least there is no big problem in use, the most investment has been added, and the equipment can still operate normally; But the small horse-drawn cart ...

1: In the operation of the motor, if dust, water stains and other debris enter its interior, it will constitute a short-circuit medium, which can damage the wire insulation layer, form an inter-turn short circuit, increase the current, increase the temperature and incinerate the motor. Therefore, dust, water stains and other debris should be prevented from entering the motor.

Prior to the introduction of frequency converters, overhead crane operators operated the cranes using contactor-based controls. For low-cycle cranes, the system is equipped with a single or two-speed motor. For cranes with higher load cycles, they use so-called wound rotor motors. ...

(1) Check whether the motor is hot. If the temperature rise of the motor is not high, you should first check whether the size of the load, the acceleration and deceleration time, and the running cycle time are reasonable, and correct the V/F characteristics, and check whether the electronic thermal protection function of the inverter is preset reasonably, such as the inverter.

1. The cause of inverter leakage According to the inverter to control the operation of the motor, the three-phase electricity is supplied to the inverter bridge (IGBT) through the filter capacitor through the rectification, and then the operation of the motor is controlled by the three-phase electricity with adjustable output frequency and voltage of the inverter. We all know that the three-phase stator winding of the motor ...

1. What is regenerative braking? If the motor decreases the command frequency during operation, the motor becomes an asynchronous generator and works as a brake, which is called regenerative (electrical) braking. 2. Can you get more braking power? Regenerated from the motor ...

The types of production machinery are complex, the functional and process requirements are different, and the torque characteristics are also different, therefore, before the application of the inverter, the first thing is to understand the nature of the load carried by the motor, that is, the load characteristics, and then select the inverter and the motor. There are three types of loads: ...

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

There are many setting parameters of the inverter, each parameter has a certain selection scale, and the inverter can not work normally due to the improper setting of individual parameters in use, so it is necessary to set the relevant parameters correctly. ...

1.SB200 fan pump special inverter, widely used in textile, printing and dyeing, washing, cable, packaging, machinery, ceramics, constant pressure water supply, constant temperature control or various OEM. 2.HG1000 high-performance light-load intelligent inverter ...

Assuming that the inverter has a built-in braking unit and additional braking resistors, it is important to pay attention to the correct wiring of the braking resistors. The braking resistor should be connected between the P terminal and the DB terminal, but not between the P terminal and the N terminal, otherwise the three-phase rectifier bridge will operate at full load when it is not working, resulting in the equipment being unable to ...

The presentation of inverters has brought a revolution to industrial automation control and motor energy saving. Industrial production is simply inseparable from the inverter, even in the daily livelihood, elevators, inverter air conditioning has become a part of the insistence, inverter from the beginning into all corners of production, subsistence. However...

When various factory equipment uses frequency conversion speed regulation, harmonic disturbances will be generated on the power supply side and motor side of the inverter (VFD), which will cause electromagnetic disturbance to the power supply network and other electrical equipment near the VFD. In addition, in order to ensure the long-term reliable operation of the VFD, the wiring of the VFD is very important. ...

Investigation of the function of the inverter system Before debugging the inverter, it is necessary to carefully read the instruction manual and related information of the inverter to be debugged to understand the use environment and precautions. Especially before the inverter is energized, it is necessary to carefully investigate and check whether the inverter has obvious problems.

Most of the damage of the inverter module is due to the damage of the driving electric, which causes the two switching devices on one bridge arm to be turned on at the same time. Inverter inverter power module damage is a common problem in other inverter equipment such as vector inverter or energy-saving inverter.

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This will help prevent the inverter's control circuit from being disturbed by harmonics in the inverter's main circuit. 2. To separate the connection of the inverter from the terminals or contacts of other control circuits, ...

1. Look After taking over a faulty inverter, remove the inverter shell and clean it up, and carefully investigate the appearance, shape, and integrity of the relevant components on the circuit board with both eyes according to the type of inverter fault. This method is about charging resistors, filter electrolytic capacitors, IG ...
