Senlan low-voltage inverter has four series of applications

First, the operation of the machine before the technical transformation The sugar separation process of a sugar factory in Yunnan uses centrifugal dehydration method. The separation machine is mainly composed of a cone drum and a drive motor, and the motor shaft is directly connected to the bowl. Solid sugar crystallized from a high concentration of sugar water, in a cone bowl ...

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This will help prevent the inverter's control circuit from being disturbed by harmonics in the inverter's main circuit. 2. To separate the connection of the inverter from the terminals or contacts of other control circuits, ...

The signal line and the power line must be routed separately: when using the analog signal to remotely control the inverter, the signal line of the control inverter and the strong current circuit (main circuit and sequential control circuit) can be separated from the inverter and other equipment to the analog interference, and the interval should be more than 30cm. Signal ...

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

When the peripheral equipment and the inverter share the same power supply, the disturbance generated by the inverter is transmitted against the power line, which will cause other equipment in the same system to malfunction. The following methods can be adopted: (1) The input device of the inverter is equipped with an EMI filter or a ferrite common-mode filter (magnetic ring) ...

1. Common faults of motor heating up too high or smoke motor Causes: 1. Excessive load; 2. Two-phase operation; 3. Blocked air duct; 4. The working temperature is too high; 5. Interphase or inter-turn short circuit fault of motor stator winding; 6. Motor stator winding grounding device; 7. The power supply voltage is too high or too low; Overhaul...

Hope Senlan inverter control panel button function diagram 1. The "FUNC/DATA" button is a programming key, press this button once to convert the operation mode, and press it again to read and write the utility code. 2."S ...

Motherboard faults are often manifested as faults that are difficult to visually identify, such as system startup failure and screen invisibility. You can use a brush to gently brush off the dust on the motherboard, in addition, some plug-in cards and chips on the motherboard are in the form of plugs.

With the rapid development of the national economy, the installed capacity of captive power plants and the planning of transmission and distribution networks have been expanding. After the power system fails, if the power supply cannot be quickly restored, it will cause huge economic losses and severe social impact. How to ensure the safety and stability of the enterprise, long-term production ...

Now, the frequency conversion speed regulation system has been widely used in the industrial production of various small and medium-sized enterprises. This is all due to our ability to provide accurate speed control and complete stepless speed regulation. Therefore, it can easily control the ascent and descent of mechanical transmissions, traverse ...

How does the hovering function of the inverter work? When the speed of the asynchronous motor is 0, the encoder response is meaningless, and it needs to be converted to V/F control, and the frequency is set to 0; The voltage is set to 0 speed at which the motor promises to withstand the current at the moment ...

From September 15th to 19th, the 22nd China International Industry Fair was held at the National Convention and Exhibition Center (Shanghai). As the first national industrial exhibition held under the normalization of epidemic prevention and control this year, the theme of this expo is "Intelligence, Interconnection: Enabling the New Development of Industries".

1. The power supply voltage is low The solution is to preset the active voltage adjustment function of the inverter, so that when the frequency is low and the rated frequency is dry, the inverter has the function of active voltage stabilization, and if the output voltage is low, the inverter will actively increase the output voltage ...

1. Connect X (switching input) drive terminal to control the inverter start-stop/forward and reverse rotation; 2. Connect to the AI (analog input) terminal to control the frequency of the inverter (perhaps made into PID closed-loop control active conditioning frequency) 3. Other DO (switching output) is used for transmission ...

A. Wound rotor asynchronous motor The rotor winding of the wound rotor asynchronous motor is a set of three-phase windings with star connection. The end points of the three-phase winding are connected to the three collector rings, which are connected to the brushes and the external resistor (for starting or speed regulation) through the collector rings. Select inverter ...

What happens when the inverter-controlled motor presses the abort button, and the motor is not controlled to speed up? 1. 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 ...

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. ...

(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 ...

A frequency converter (VFD) is an electrical energy control device that converts a power supply to another frequency by using the on-off effect of power semiconductor equipment. It can realize the soft start, frequency conversion speed regulation, improved operation accuracy, power factor, overcurrent/overvoltage/overload protection of AC asynchronous motor, etc.
