Comparison of three speed regulation methods for Delta DC motors

1. Each VFD should be cleaned and protected once a quarter. Protecting and cleaning equipment must have specific records and the signature of the person in charge. As long as the management is in place, the task can be completed with quality and quantity; 2. Before cleaning, the power supply must be blocked, and the voltage must be reduced to a safe voltage before starting to work. ...

1. When the Delta inverter breaks down in the future, it is best not to hand it over to someone who has no experience in repairing the inverter to repair the inverter, otherwise it may get worse and worse. Sometimes it's about to fuse, be sure to check whether there is a problem with the module, some electricians have not experienced it, and immediately install a good fast melt (definitely not ...

Fault 1: Overcurrent in acceleration Clarification: Overcurrent in acceleration Solution 1: Check whether the wiring from U-V-W to the motor is poorly insulated; 2: Increase acceleration and deceleration time; 3: Replace the inverter with a larger output capacity; 4: Reduced (P54) torque ...

Automatic: P0-02 Drive Status Display Parameter Function: 07Motor Speed (r/min) P1-01 Control form and control command input source setting parameter function: 02 Select S form (r/min) P1-38: Zero speed detection accuracy (no response below set speed) P1-4 ...

Human Machine Interface (HMI) is a digital product that allows operators to communicate with automation equipment. The human-machine interface provides a variety of communication ports to facilitate communication with a variety of equipment, and the touch panel allows the operator to intuitively set parameters.

Not long ago, Delta was awarded the "2020 Excellence Award for Optimal Allocation of Human Resources Resources" by the Human Resource Management Service Project Organization "Future", which stood out from more than 5,000 companies. This is also the second time since 2018 that Delta has won this honor. Delta ...

Industrial control automation products inverters are depicted as power-saving, energy-saving control automation products, therefore, many people will think that as long as the equipment is installed with inverters, it will be able to save energy, but this is not the case. The inverter of industrial automation products itself produces energy-saving ...

In addition to adhering to the high reliability, excellent efficiency and outstanding power of Delta's UPS products, the N1-3kVA series has three obvious core advantages: 1. High availability planning Delta N 1-3kVA series ...

In the inverter problem, it is often encountered that the energized panel does not appear. Generally speaking, the problem of the inverter panel not showing up is usually caused by three parts, one is the poor contact of the contactor, the second is the control panel of the inverter, and the third is the damage of the power module that supplies power to the control panel.

　　Delta's frequency modulator frequency modulation is mainly operated on the control panel, and the process: 1. Press the Menu button to enter the parameter programming menu, 　　​ 　　2,P0.01=1,Enter this parameter to complete the correction frequency of the panel button, ...

1. Harmonic problems The equipment that plays the role of switching in the main circuit of the inverter must generate harmonics in the process of turning on and off the circuit. The lower harmonics generally have a greater impact on the motor load and cause torque ripple; The higher harmonics increase the leakage current of the inverter's output cable, making ...

(1) Ambient temperature: Like other electronic equipment, the inverter has certain requirements for the ambient temperature, which is generally "-10-+40°C". Because the inverter is a high-power electronic equipment, it is very easy to be affected by the working temperature, but in order to ensure the safety of the inverter's work.

1. The problem of the inverter and the motor itself If the motor has been used for a long time, it is not good to clean the insulation function, or the bearing may be stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced, the fixtures of the motor are loose, etc.

Correct installation, operation and maintenance of the reducer is an important part of ensuring the normal operation of mechanical equipment. Therefore, when you install a planetary reducer, it is necessary to carefully assemble and operate it in strict accordance with the following matters related to the operation of the device. ...

The rapid development of the national economy has opened up a broad shopping mall space for the growth of the civil aviation industry. In order to meet the surge in the number of flights, an international airport in Northwest China has invested in the third phase of the expansion project, and has been listed as the "number one project" for civil aviation development and the "benchmark demonstration project" for national civil aviation.

Installing a variable-frequency drive (VFD) on the power frequency motor can complete the accurate control and speed regulation of the motor, and improve the efficiency and accuracy of the motor. However, if not properly equipped and used, it may cause the following hazards: ...

The motor can be started after the work is completed before use, and attention should be paid to the investigation of the motor, transmission device, production machinery and line voltage and ammeter, if there is an abnormal phenomenon, it should be stopped immediately, the fault should be identified and swept away, and then it can be closed and started again. When the motor is running, ...

One is hardware, similar to the CPU reset circuit, which gives the downtube a short high-level drive pulse during the initial power-up, and then the voltage drops to 0 to cut off the downtube. The second is the software, when the CPU is operating normally, it outputs a square wave pulse that only needs to be turned on by the lower three tubes, so that the upper tube ...
