If it is a newly installed inverter, it is generally necessary to consider the wiring problem, you can first change the parameters to switch to the panel control, the panel is given the frequency, and then see if the inverter operation will appear in this ...

The control specifications of the inverter cabinet include reliability, accuracy, safety, environmental habits and versatility, etc., which are important guarantees to ensure the normal operation and safe production of the inverter cabinet control system. Reliability specification: The control system should have high reliability and can be used for a long time.

Limit switch is an electromechanical control element used to detect the direction of the movement of the machine or equipment, and send a signal when the specific position is in a specific direction to control the operation or stop of the equipment. It is often used in industrial production processes, such as CNC machine tools, conveyors, loading and unloading robots, etc. ...

1. The rectifier module is damaged It is usually caused by grid voltage or internal short circuit. In the case of excluding internal short circuits, the rectifier bridge is replaced. 2. The inverter module is damaged It is usually caused by damage to the motor or cable and the failure of the drive circuit. After repairing the drive circuit, ...

The direct torque control (DTC) function of the inverter is another high-performance communication frequency conversion speed regulation system developed after vector control. In the mid-80s of the 20th century, the German scholar Depenbrock proposed the theory of direct torque control in 1985, and his idea was to combine the electric motor and the inverter.

1. Obtain accurate motor parameters from low to high parameters at different frequencies, and establish motor models of corresponding frequency bands in different frequency segments, so that the inverter can control the motor from low to high. 2. V/F control (1) It is possible to select 15 pre-set V/...

1. The cause of inverter leakage According to the inverter to control the operation of the motor, the three-phase electricity is supplied to the inverter bridge (IGBT) through the filter capacitor through the rectification, and then the operation of the motor is controlled by the three-phase electricity with adjustable output frequency and voltage of the inverter. We all know that the three-phase stator winding of the motor ...

Sunland inverter and soft start is a first-class, reliable and reliable motor control system, which is able to meet the needs of various applications. The advantages of expected Sunland inverters and soft start are: 1. Performance: Expect Sunland inverter and soft start...

Belt conveyor is a kind of continuous conveyor, which is one of the main types of fixed or escorted cranes. Belt conveyor is the use of friction to convey the dynamic, with belts, steel belts, steel fiber belts and chemical fiber belts as a kind of compliance with the transmission of materials and traction operations.

1. Preparation process: Abort the device and admit that the motor is completely aborted. Press the stop button on the operator panel to stop the operation. Disconnect the external mains power supply (low-voltage cabinet drawer). Adequate security treatment should be carried out to ensure that it is indeed disconnected and that it does not ...

1. The control accuracy of the vector type is higher than that of the general type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, and is suitable for use in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If it is used in some of the more common fields ...

(1) Check whether the motor is hot. If the temperature rise of the motor is not high, you should first check whether the size of the load, the acceleration and deceleration time, and the running cycle time are reasonable, and correct the V/F characteristics, and check whether the electronic thermal protection function of the inverter is preset reasonably, such as the inverter.

1. The "FUNC/DATA" key is a programming key, press this button once to convert the operation mode, and press it again to read and write the function code; 2. The "SET/>>" button is the display switch and shift key, press this key to switch the display content, and press it again to ...

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. ...

Mechanical control: It is expected that Sunland inverters are widely used in mechanical control, such as ...

1. Overpressure leads to brake pipe breakdown. The so-called overvoltage of the inverter refers to the fact that the inverter voltage composed of various reasons exceeds the rated voltage, which is reflected in the DC voltage of the inverter DC bus. The overvoltage alarm generally appears at the time of shutdown, and its main ...
