Inverter interference mode and treatment method - Xinjie

Radiative disturbance from space The most useful method for radiation disturbance is metal shielding. Space radiated electromagnetic fields are mainly caused by power networks, lightning, radio broadcasting, radar, etc., and are generally referred to as radiation disturbances. Its impact mainly goes through two paths: one is ...

Following the launch of XDH, XLH series 16-axis and other models, Xinjie has achieved good market feedback, and the XLH-30A32 low-profile controller to be launched today can be expanded by 32 bus nodes, and has better performance in basic performance and bus control ability. ...

PLC programmable logic manipulators are the core part of industrial control. According to the number of I/O points of PLC, PLC can be divided into three categories: small PLC, medium and large. It is a digitally operated electronic device designed for industrial production. It uses a programmable memory to store programs that execute user-facing ...

Motor overload: There is no need to set overload maintenance parameters in frequency conversion. The inverter generally acquiesces to the motor overload maintenance based on the motor power. Generally, it is 1.2 times 60 seconds to report the overload problem. The overload factor is not the same for different frequency converters. ...

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 ...

(1) What is the current setting value of the thermal relay? The setting current of the thermal relay refers to its action current, that is to say, it is adjusted between 0.95 - 1.05 times of the rated current of the motor being maintained.

(1) The analog signal is a small signal, which is very susceptible to external interference, and a double-layer shielded cable should be selected; (2) High-speed pulse signals (such as pulse sensors, digital disks, etc.) should be shielded cables, not only to prevent external interference, but also to prevent high-speed pulse signals from low-power.

On April 21, with the theme of "I2C More Intelligent Industrial Control", the new product launch and brand promotion conference of Xinjie Intelligent Control was successfully held at Gusu Shangri-La Hotel. At the meeting, in addition to the release of new products, it also discussed the connotation of intelligent industrial control, application scenarios, and the outlook of shopping malls.

1. Look inside the electrical cabinet, for example, to see if there are small animals and their droppings, and whether there are condensation or water marks. If the dust in the cabinet is large, please clear the external radiator of the inverter. 2. Assuming that the humidity is relatively large, there are condensation or water marks, please open the cabinet door first, ventilate and dehumidify, you can use electric fans, etc.

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 ...

1.XG1 series is the latest modular medium-sized PLC of Xinjie, aiming at the domestic high-end market. peculiarity Medium-sized series PLCs with powerful functions and larger storage capacity Support 4 channels of 200K high-speed pulse transmission ...

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.

Small PLC manufacturers introduce that PLC products have a wide variety of products, and the specifications and performance are also different. The classification of PLCs is usually based on their structure, function and number of I/O points. 1. Classified by input/output points (1) ...

It is necessary to route the signal line and the power line separately: When using the analog signal remote control inverter, in order to reduce the disturbance of the analog signal of the VFD and other equipment, please separate the signal line of the VFD control from the strong current circuit (main circuit and sequential control circuit). The spacing should be more than 30cm. Even in the control ...

(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 ...

Problem example 1 On the telegram OC problem, measure the 5, 6, and 7 pins of N1 to be 2V. Pin 7 is not 0V for the alarm reason. 1. The "imaginary short" rule of the amplifier is still established, and the N1 chip is good to judge, but the fault is in the bias circuit. 2. Further analysis, at this moment the differential amplifier has ...

The creation of the touch screen screen is done by TouchWin editing tool software. Each screen includes each control menu and video window, and the home page can be written by the relevant units to write the advertising screen welcome speech or system model description. The system mainly includes the following items: ...

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 ...

Common problems with Xinjie touch screen Poor contact Touch screen installation problemRemove the screen from the control cabinet and perform an operational test. If there is no problem with the operation, i.e. the installation problem causes the installation size to be re-measured, do not install it too tightly so as not to squeeze the touchpad.
