Control the hovering function operation and principle of the inverter - Sunland inverter

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.

Robot contactors are noisy? Cause: It is likely that the joint contact surface of the contactor is uneven, and the surface is sand or rust. The result will constitute a phase loss, which will lead to the burnout of contactors, switch frequency conversion and other components. Solution: will control the ...

After the inverter selection is completed, it is necessary to consider whether other peripheral equipment needs to be equipped according to the actual situation of the site. The peripheral equipment for frequency converter selection mainly includes circuit breakers, reactors, contactors, braking resistors, etc. 1. Circuit breaker ...

1. Discrimination The inverter power module mainly includes IGBT, IPM, etc., check whether the appearance has exploded, and whether there are ablation marks between the terminal and the connected printed board. Use a multimeter to check whether C-E, G-C, G-E have been passed, or use a multimeter to measure whether the resistance of P to U, V, W and N to U, V, W is inadequate.

Sunland HOPE530 series inverter is a high-performance, high-reliability intelligent controller, widely used in a variety of industrial occasions. It is easy to operate, diversified equipment and high quality, and has become one of the intelligent power control equipment trusted by users. ...

From October 28th to 29th, the "First National Tailings Engineering and Comprehensive Utilization Skills Seminar" sponsored by the China Nonferrous Metals Society was successfully held in Dexing City, Jiangxi Province. From China Nonferrous Metals Society, China ENFI, Jiangxi Copper, Beijing Institute of Mining and Metallurgy, University of Science and Technology Beijing and other countries...

Before the asynchronous motor is equipped with an inverter, let's take a look at the three major types of mechanical equipment loads: 1. Constant torque load: such as conveyor belt and mixer; When the inverter drags the load of constant torque nature, the torque at low speed should be large enough, and the overload should be large enough. If you need ...

1. How to distinguish between heavy faults and light faults According to the occurrence time of inverter faults, we can divide the types of faults into two categories: sudden faults and intermittent faults: (1) The sudden fault of inverter repair refers to the failure of the equipment when it is running, without warning.

After inspection, the circuit board of the machine is composed of a fan switching power supply board, a control board with a switching power supply and a driving board, etc., the fan power supply and the control board operation power supply are independent of each other, the fan power supply output is normal, and the control board operation power supply is not output due to the problem. ...

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 ...

Dynamic "fast response" DC motors are rectified constrained and excessively high di/dt is not allowed. The asynchronous motor is only constrained by the capacity of the inverter, and the multiple of the forced current can be very high, so the speed echoes quickly, generally reaching the millisecond level, which has surpassed the DC motor in terms of speed. At low frequencies ...

1. Select the inverter according to the load characteristics Second, when selecting the inverter, the actual motor current value should be used as the basis for the selection of the inverter, and the extra power of the motor can only be used as a reference. Secondly, it should be fully considered that the output of the inverter contains higher harmonics, which will form the power factor of the motor.

1. What is frequency conversion resolution? What's the point? In the case of digitally operated inverters, the output frequency is given in a given order, even if the frequency command is an analog signal. The smallest unit of this gradient is called the variable resolution. Change...

1. The ambient temperature ---- is generally "-10-+40°C"; Derating between 40 and 50°C, the additional output current must be reduced by 1% for every 1°C increase. If the ambient temperature is too high and the temperature changes greatly, the insulation of the inverter will be greatly reduced, which will affect the life of the inverter. ...

Sunland's low-voltage SB70 inverter integrates a high-precision rotor magnetic field directional vector control algorithm, with 250% instantaneous torque control capability. It has the original multi-form PLC operation function, which is especially suitable for industrial cleaning equipment and manufacturing equipment. Practical multi-speed function: two sets of parameters, can be rooted ...

1. Motor control The inverter is mainly used in the field of motor control, which can complete the speed control, torque control, and azimuth control of the motor. The inverter can adjust the speed and load of the motor according to the process requirements, which can improve the output power and quality. 2. Air conditioning refrigeration ...

Hope Sunland Technology Co., Ltd. is a national key high-tech enterprise dedicated to the research and development of high, medium and low voltage frequency conversion technology and the design, development, production, sales and service of related products.

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. Delta's super password-B series: 57522; - H-series: 33582; S1 series inverter universal password: 575222. Second, Huifeng inverter (that is, now Ou Rui inverter), the general super password of its products is: 18881500-G 1500-P 1000- ...

1. Whether it has perfect maintenance function There will be many problems in the production process of the equipment, and if you want to prevent accidents, the equipment must have a perfect maintenance function, so as to prevent the loss of the enterprise. Therefore, when buying an exhaust fan inverter, you need to understand the safety function of the equipment first.
