Single-table driver for HLP2B

The basic components of PLC for power production: 1. Memory 　　​ 　　The memory that registers the architecture software is called the architecture program memory. The memory that registers the application software is called the user program memory. 2. Power supply ...

1. Look: The normal operation of the motor has a great relationship with the surrounding environment. Therefore, during the daily inspection, check the water leakage and dripping conditions around the motor (which will cause the low insulation of the motor to form breakdown and burn out), and check whether the peripheral of the motor has affected its ventilation and heat dissipation ring.

The XGT series is a creative PLC product family that combines LS's power generation technology capabilities to provide next-generation solutions based on open networks, ultra-high-speed processing speeds, compact scales, and greatly improved software for the engineering environment. XGT series for a variety of ...

An important difference between servo and frequency conversion is that frequency conversion can be without encoder, while servo must have an encoder for electronic commutation. 1. What the two have in common: The AC servo technology itself is to learn and apply the technology of frequency conversion, and the servo control of the DC motor is based on the ...

1. The low-voltage fuse cannot be used as an overload maintenance of the motor. 2. The additional voltage of the fuse must be greater than or equal to the operating voltage of the distribution line. 3. The additional current of the fuse must be greater than or equal to the ...

First, the process requirements of the grinding machine: The grinding machine is a kind of textile machinery, and its function is to polish the dyed cloth to improve its added value, which is an important process in the printing and dyeing process. The traditional drive mode is driven by a DC motor, which is linked with the lifting rod ...

1. Trapezoidal stairs start from the horizontal line and end up with a vertical line (generally you can omit not to draw, only draw the left busbar). On the left side of each row is the junction combination, indicating the conditions that drive the logic coil, while the logic coil indicating the effect can only be connected to the bus on the right. The contact can not appear in the coil right ...

Servo drives and frequency converters are defined differently The driver, also known as servo manipulator and servo amplifier, is a kind of manipulator used to control servo motors, and its function is similar to that of a frequency converter acting on a general communication motor. It is part of the servo system, mainly used for high-precision positioning ...

1. Select the corresponding category of contactor according to the control object, operation times and application category of the contactor. 2. Select according to the rated voltage of the line at the application location. 3. Select the rated current of the main contact of the contactor according to the load capacity. 4. About the voltage level of the lead coil ...

The working principle of the power production contact is: when the contact coil is energized, the coil current generates a magnetic field, and the generated magnetic field leads the static iron core to produce electromagnetic attraction to the iron core, and drives the AC contact action, the normally closed contact is disconnected, the normally open contact is closed, and the two are connected to each other. When the coil is de-energized, the electric ...

1. Outstanding frequency conversion speed regulation characteristics Completing the frequency conversion speed regulation of asynchronous motor is the "century wish" that people have been waiting for since the creation of asynchronous motor for 100 years. Through unremitting improvement, enhancement and perfection, the speed regulation function of VFD is not bad, that is, compared with the DC speed regulation system, the part ...

The protection of the motor by the power converter mainly includes the following aspects: overvoltage protection, undervoltage protection, overcurrent protection, phase loss protection, inverter protection, overload protection, grounding protection, short circuit protection, overfrequency protection and stall protection. ...

LS power automation drives are mainly for industrial enterprises and construction enterprises, including municipal, metallurgical, electric power, chemical and other power-oriented industrial enterprises, car, food and beverage, pharmaceutical and other professional enterprises, as well as OEM equipment manufacturing enterprises. ...

LS inverter and LG inverter are the same, there is no difference between the two. LS inverter, the full name of LS AC inverter governor, after supplying a variety of configurations, converts direct current into communication power, and changes the general power supply ...

The inverter circuit is the first part of the inverter The function of the DC central circuit is to smooth the output of the rectifier circuit to ensure that the inverter circuit and the control power supply can obtain a DC power supply with higher quality. When the rectifier circuit is the voltage flow of the central circuit, the primary component is the electrolysis of Darongtong ...

Due to poor contact of network connectors, or due to disturbance and other problems, DP networks that have been used for a long time may show a "transient disconnection" situation, that is, occasionally disconnected instantaneously, and quickly recover to normal. If OB86 is not downloaded, the CPU will stop during a transient outage. Now all over the option to download a ...

When the LS power generation module is put into operation, its working process is generally divided into three stages, namely input sampling, user program fulfillment and output rewriting. The completion of these three phases is called a scan cycle. During the entire operation, the PLC's CPU repeatedly performs the upper ...

In Clarivate's recent statement, LS Electric was named one of the top 100 innovators in the world. The trophy handover ceremony was held in Anyang, LS Electric R&D Park, with Kim Yeong-geun, Chief Technical Officer of LS Electric, and Ahn Seong-sik, CEO of Clarivate Korea, acting as representatives of both parties.

Switch Mode Power Supply (SMPS) will cause the base of the switch tube to fail to get the switching pulse and intermittently operate due to the short circuit of the load, the failure of the self-vibration circuit and the loss of control of the protection circuit, which makes it difficult to locate the shortcomings of SMPS. Difficult to repair the work ...

Myth 1: Connect electromagnetic switches and electromagnetic touches in the output circuit of the inverter In practical application, some occasions need to use the touch device for frequency converter switching: such as switching to the power frequency state when the frequency conversion is faulty, or the election is used to drag two methods, a motor is faulty, and the variable frequency is used.
