Common models of Xinjie PLC and their characteristics

1. Select the power supply with excellent performance and press the disturbance introduced by the power grid The power supply of the PLC controller is powered by a non-power line, and is powered by a special line directly led by the main bus of the low-voltage distribution room. Barrier transformer should be selected, the transformer capacity should be 1.2-1.5 times larger than the actual need, and can be used in the barrier...

The primary role of the TP contact screen Supervision: Reflect the internal bit status of the PLC in various ways such as data, curves, graphics, animations, etc., store the numerical value, and then intuitively reflect the process and direction of the industrial control system. Exercise...

1. Acknowledging the characteristics of the load such as load type, speed, and nature; 2. Acknowledging whether it is continuous work, long-term work, short-term work and other work characteristics; 3. Acknowledging the maximum consumption output value and the extra output value; 4. Acknowledging ...

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

The damage of the inverter to the motor contains two aspects, the damage of the stator winding and the damage of the bearing, this damage usually occurs in a few weeks to more than ten months, the detailed moment and the inverter brand, the motor brand, the motor power, the inverter carrier frequency, the cable length between the inverter and the motor, the ring ...

The problem of the inverter is not only affected by external factors, but also by internal factors. 1. The inverter parameter setting is unreasonable and countermeasures to make the inverter work normally, in addition to the normal equipment, the parameter setting is also very important, if the parameter is not set properly, it will not be able to ...

The MS series of servo motors can be installed in either the horizontal or vertical direction. However, if it is installed incorrectly, or in an unsuitable place, it can shorten the life of the motor or cause unexpected accidents. 　　Storage temperature In the unpowered state ...

(1) The PLC itself should be grounded according to the specified wiring specifications and grounding conditions, and attention should be paid to prevent the use of common grounding wires with Xinjie servo, and the two should be separated as much as possible when grounding. (2) When the power supply condition ...

Control principle: PLC controls the operation of the servo motor by controlling the servo motor. 1. The PLC sends a pulse signal to the servo motor driver, pay attention to the driver. 2. The servo motor drive according to the ...

In the process of century industry, the more top-level software and hardware planning for the suspension of frequency conversion skills, first according to the characteristics of traditional air compressor motors, comprehensively analyze the causes of energy consumption and operation characteristics, so as to plan the control of frequency conversion skills speed regulation, air skill tightening, pressure sensing skills improvement, etc.

1. Introduction TP Contact Industrial Graphic Displayer (referred to as contact screen) is a human-machine interface (known as HMI or MMI in foreign countries) that connects humans and machines (mainly PLC), which is known as the face of PLC. It is a generation ...

At present, in the domestic PLC market, there are many kinds, but there are not many domestic PLC manufacturers with real strength, most of the domestic PLC is not an individual without legal person qualifications, or a single-chip microcomputer enthusiast, from the domestic PLC factory to buy the underlying programming code or buy a domestic PLC chip (the domestic P ...

Introduction to Thermal Transfer Transfer printing refers to a printing method that selects the corresponding pressure to transfer the graphics and text on the intermediate carrier film to the substrate, and according to the different selection pressures, transfer printing can be divided into water transfer printing, heat transfer printing, air transfer printing, screen transfer printing, low temperature transfer printing and so on. In the meantime, the heat ...

(1) There is no need to adjust the parameters, we can maintain the original parameters (default value) when the inverter leaves the factory. (2) It is the parameter that needs to be set and changed before the trial operation. (3) It is a parameter that is adjusted in the operation of the demand. Frequency converters ...

Input and output module, if it is the kind of relay output, it is normal to have a little movement, because the relay is a mechanical equipment, there will be a little noise during the action, but the average person can not hear it, if it is obvious, it is estimated that the relay is broken, such as a short circuit between the turns of the coil, please pay attention to: Rongji point ...

The voltage waveform output by the inverter is similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components, especially the higher harmonics will increase the output current of the inverter, form the motor winding heating, produce vibration and noise, accelerate the aging of insulation, and even ...

1. The speed regulation power is high, which is an efficient speed regulation method. This is because after the frequency change, the motor is still working in close proximity to the synchronous speed, and the rated slip is fundamentally adhered to. It's just that in the frequency conversion equipment system, there will be conversion loss, and because of the influence of higher harmonics, the loss of the motor will increase.

Motion control has a significant period characteristic, it is a variety of high-tech generalization, used to bring industrial automation, office automation and home automation to a higher stage. Nowadays, motion control is mainly composed of variable frequency drive (VFD), electric motor, control ...

Because the current at the input and output ends of the inverter contains high-frequency components, the leakage current formed by the high-frequency components when the inverter is driven is greater than that when the grid power supply is supplied. Because there are many varieties of circuit breakers, in some cases, even the inverter wires and motors ...

The XDHI XLH series of 16-axis high-performance EtherCAT controllers is the perfect choice for small motion control. Product model XDH-30A16-E/XDH-30A16L-E Small/16-axis type Frequency: 600MHz Program Capacity: ...
