Sunland inverter wiring standard

Assuming that the inverter has a built-in braking unit and additional braking resistors, it is important to pay attention to the correct wiring of the braking resistors. The braking resistor should be connected between the P terminal and the DB terminal, but not between the P terminal and the N terminal, otherwise the three-phase rectifier bridge will operate at full load when it is not working, resulting in the equipment being unable to ...

Poor choice This should be the situation that friends have encountered the most in the Z, the situation of large horse-drawn carts and small horse-drawn carts is everywhere. The big horse-drawn trolley is not bad, at least there is no big problem in use, the most investment has been added, and the equipment can still operate normally; But the small horse-drawn cart ...

The wearing parts of the driver mainly include electrolytic capacitors for filtering and cooling fans, and their service life is closely related to the environment and maintenance of the operation. Depending on the operating moment, the user can determine whether a wear part needs to be replaced. Cooling ...

The inverter is a motor control (speed regulation) device that uses the on-off effect of power semiconductor devices to convert the power frequency power supply to another frequency. Composition 1: 1. Rectifier unit: convert the communication electricity with fixed operating frequency into DC ...

(1). Constant torque load Different speeds, load resistance and torque base are stable. The output power is directly proportional to the rotational speed. Such as belt conveyors. (2). Constant power load Different speeds, stable load power base ...

In order to ensure the safe, efficient and reliable operation of the inverter, the following keys should be grasped when using the inverter: 1) It is necessary to reliably ground the grounding terminal of the inverter, so as to effectively press the radio frequency disturbance and enhance the reliability of the system.

It is necessary to separate the signal line from the power line: when using analog signals for long-distance control of the inverter, in order to reduce the disturbance of the analog amount from the inverter and other equipment, please separate the signal line of the control inverter from the strong current circuit (main circuit and sequential control circuit). Inverter ...

1. Select the inverter according to the load characteristics, such as the load is constant torque load, you can choose Siemens MM440 inverter, ABB ACS800 series inverter, etc.; If the load is a fan or pump load, you can choose Siemens MM430 inverter, ABB ACS510 series inverter, etc. 2、 ...

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.SB200 fan pump special inverter, widely used in textile, printing and dyeing, washing, cable, packaging, machinery, ceramics, constant pressure water supply, constant temperature control or various OEM. 2.HG1000 high-performance light-load intelligent inverter ...

In the process of operation, try to ensure that the inverter (hereinafter referred to as -VFD) has a satisfactory acceleration and deceleration time, and the VFD has its own soft start function when starting or accelerating; When the power is shut down or the speed is slowed down, it has the function of soft shutdown. Add acceleration and deceleration times as much as possible within the range promised by the device. When the device requires ...

1. The inverter itself has strong electromagnetic disturbance, which will disturb the operation of some equipment, so we can add a cable sleeve to the output cable of the inverter. 2. The control line in the inverter or control cabinet is spaced at least 100mm, and the power cable is at least 100mm. 3. In the purchase of inverter ...

1. Repair the damage of the inverter rectifier block The damage of the inverter rectifier bridge is also one of the common faults of the inverter, the inverter rectifier block in the early production is mainly diode rectifier, and now some rectifier blocks choose the rectifier mode of thyristor (voltage regulation and frequency modulation inverter). Middle...

In general, there is a problem with the maintenance trip of the VFD. If you look at the faulty code, you can see what kind of fault is causing it. 1. The selection talent of VFD may be too small; Generally, when selecting VFD, it should be about 20% larger than the rated power of the motor, so that when the motor reaches full load...

Planning specifications: The planning of inverter cabinets should conform to relevant national norms and industry norms, such as GB/T15576-2018 "Low-voltage Distribution Cabinet", GB7251.1-2017 "Low-voltage Complete Switchgear and Control Equipment", etc. Material specifications: The materials of the control cabinet should conform to the relevant codes and regulations.

(1) The VFD should be installed in the control cabinet. (2) The VFD is best installed in the center of the control cabinet; The VFD It should be vertically installed with the top and bottom protected from large parts that may obstruct the exhaust and intake. (3) VFD control cabinet or partition, or the upper and lower parts of the necessary device ...

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. ...

It is important to set the torque to improve the function. When the power frequency of the motor decreases, the speed of the motor will also decrease, and if the load torque remains unchanged, the output power will also decrease. According to the principle of conservation of energy, if the rotation of the load ...

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, ...

Natural heat dissipation methods are generally used for heat dissipation of small-capacity inverters, because their operating environment should be well ventilated and free of dust and floating objects. The drag targets of such inverters are mostly household air conditioners, CNC machine tools, etc., and the power is small. Still...
