Operating instructions for the Reynolds control panel

1. The heat dissipation system is different: Generally, the cooling fan in the fan is in the same line as the fan movement, while the two are separated in the inverter motor. Therefore, when the frequency conversion of the fan is too low, it may burn out due to overheating. 2. Frequency conversion ...

Overload can be different Servo drives generally have 3 times the overload ability, which can be used to overcome the inertial moment of the inertial load at the moment of start-up, while the frequency converter generally allows 1.5 times the overload. Handling precision Servo control ...

1. The inverter can not speed up the frequency increase when it starts with load The 1366S-BR 040 inverter carries a load of 37 kW fan motors. During the trial operation, it was found that the inverter could not speed up the frequency increase normally, and the HIM display was speeding up. The inverter only swings at 1-4 Hz, and the motor emits a buzzing ...

There are two types of inverter parking. One form is called "free parking". As the name suggests, it is to quickly "power off" the motor, so that the motor can slide and park by its own inertial force (OFF2 parking); The other form is called "brake parking". So this "brake parking ...

1. The inverter itself has a strong electromagnetic disturbance, which will disturb the work 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 at least 100mm away from the power cable, etc. ...

From September 23rd to September 25th, 2020, the 2020 China International Paper Technology Exhibition was held in Hall D1 of Suzhou International Expo Center.

1. Test rectifier circuit: To the P end and N end of the DC power supply inside the inverter, adjust the multimeter to the resistance X10 gear, the red watch rod is connected to P, and the black watch rod is separated from R, S, T, and there are tens of ohms of resistance in normal times, and it is basically balanced. Instead, connect the black watch rod to the P end, and the red watch stick will be ...

Reynolds inverter RNB1000 series E.oC3 constant speed operation overcurrent fault solution Reynolds inverter fault codes: E.oC3 Reynolds inverter fault phenomenon/type: Constant speed operation overcurrent Possible causes of Reynolds inverter failure: ...

The output voltage of low-voltage general frequency conversion is 380-650V, the output power is 0.75-400kW, and the operating frequency is 0-400Hz. Its control methods have gone through the following four generations. 1U/f=C Sinusoidal Pulse Width Modulation (SPWM) Manipulation MethodIts Characteristics ...

(1) The multi-pronged PWM control method is selected, and the output voltage waveform is close to the sine wave. (2) The rectifier circuit is multiplied, the number of pulses is as high as 36, the power factor is high, and the input harmonic is small. (3) Modular design, compact structure ...

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

The output of the inverter is controlled by PWM (pulse width modulation, similar to high-speed switching), so a high frequency leakage current will occur, if you want to install a general leakage disconnect switch on the primary side of the inverter, it is recommended to select a sensitivity current of more than 200mA for each inverter and the action time is 0.1 seconds ...

Soft starters and frequency converters are two completely different products. The inverter is used in the local area where speed regulation is required, and its output not only changes the voltage but also changes the frequency at the same time; A soft starter is actually a voltage regulator, which is used when starting a motor, and the output only changes the voltage and does not change the frequency. Change...

The first way to use the inverter is to change the output frequency to achieve the controllability of the motor speed, so do you know what steps to complete the output frequency controllability? One of the first and foremost key points is how to complete the change of the frequency signal supplied by the inverter equipment.

1. FUN button; Press the FUN button to enter the settings menu F00; 2. Press and hold the up button or down button to scroll to the code that needs to be set; 3. Press the FUN button to confirm at this moment, and adjust the entry parameters to the required value; 4、 ...

A frequency converter is a power electronic device that can change the frequency of an AC power source to control the speed and output power of a motor. Inverters are widely used in industry, aviation, metallurgy, petroleum, chemical industry, electric power and other fields.

The lightning protection measures of the inverter equipment are another important peripheral measure to ensure the safe operation of the inverter, especially in the area where lightning is active or in the lively season, this problem is particularly important. Today's inverter products are generally equipped with mines.

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This effectively prevents 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, ...

1. The interval between the inverter and the motor should be as short as possible. This reduces the cable's capacitance to ground and reduces the source of disturbance. 2. The control cable is shielded cable, the power cable is shielded cable or from the inverter to the motor.
