Inverter selection conditions and precautions - Reynolds

Motion control has obvious period characteristics, it is a variety of high-tech generalization, used to push industrial automation, office automation and home automation to a higher stage. Nowadays, motion control is mainly composed of variable frequency drive (VFD), electric motor, control ...

1. EPS the first use of the emergency power supply, the battery pack should be charged continuously for 48 hours after discharging protection; 2. EPS emergency power supply to keep the whole machine dry, clean, free of dust and foreign objects, wipe with a soft cloth after shutting down, and strictly ...

Inverters are mainly divided into two categories according to the frequency conversion method: communication/DC/communication and communication/communication inverters. Here we take the widely used general "communication/DC/communication" as an example to briefly talk about its structure and operating principle. As can be clearly seen from the above diagram, the communication/...

1. See if it is energy-saving. When selecting equipment products, many business managers will take into account the energy-saving embodiment, which is due to the excellent energy-saving embodiment of the product, which can save a lot of money and resources.

1. Safety precautions 1. The primary requirement is to have certain electrical professional knowledge, and understand the job site, understand the equipment status, and have certain electrical operation technology. 2. Determine the electrical ...

1. What are the factory recovery parameters of Reynolds inverter? N600 = 100 (often press the WR button for 3-5 seconds), it is necessary to be in the shutdown state to be effective. 2. In the parameters of the N308 motor of the inverter, is the [motor leakage inductance reactance] specified sub-leakage inductance or rotor leakage inductance react? Decide...

1. When the servo motor of the robot is running at a very low speed, it is fast and slow, just like a creeping machine. Low-speed prostrate servo motors are usually caused by low system gain. Please adjust the parameter N.10.N.11.N.12 to adjust the system gain appropriately, or the automatic gain adjustment function of the running driver ...

Reynolds soft starters include soft starters for high, medium and low voltage motors, including JJR1000 series, JJR2000 series, JJR5000 series, and RNB3000 series frequency converters. Reducing the starting power supply avoids voltage drops and voltage dips in the power supply. Smooth start-up avoids product damage. ...

1. The acceleration moment is too short. Theoretically, the longer the acceleration time, the stronger the load lifting capacity. If the acceleration time is set too short, some VFDs will show an overcurrent or overload, overtemperature alarm, while others will not, and will only be stuck in a certain frequency band. 2.The V/F ratio is too large Some of this ...

First, the selection of inverter power The system power is equal to the product of the inverter power and the motor power, and the system power is higher only when both are operating at a higher power. From the perspective of power, when selecting the power of the inverter, we should pay attention to the following points: 1) ...

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.

Water pump inverter pressure conditioning steps: 1. Open PID closed-loop control; 2. Close the pressure circuit; 3. Set the pressure feedback and set the given pressure; When the pump speed is changed, the outlet pressure can be changed. Adjust the operating frequency of the VFD. The higher the frequency, the higher the pump speed and the higher the pressure. About ...

Variable frequency speed regulation can be used in most motor drag occasions, because it can provide accurate speed control, so it can easily control the rise, descent and variable speed operation of mechanical transmission. The use of frequency conversion can greatly improve the efficiency of the process (the variable speed does not depend on the mechanical part) and at the same time ...

Most inverter brand products can rely on the heat generation of internal electrical components to remove moisture during normal use. If you don't have to do it for a long time, it's easy to get wet. The chip pins, penetrating resistors, capacitors, and inductor pins of the DIP package will be severely rusted or desoldered, resulting in on-resistance ...

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.

Take the RNB2000 series inverter as an example. The model number of the RNB2000 series 37kW inverter is: RNB2037-U RN: on behalf of Reynolds; B: low-voltage frequency conversion governor; 2: 2000 series; ...

Misunderstanding: connect electromagnetic switches and electromagnetic contactors in the output circuit of the inverter In actual use, some occasions require the use of contactors for frequency converter switching: such as when the frequency conversion is faulty, switch to the power frequency operation, or when the one-to-two method is adopted, a motor is faulty, and the variable frequency is used.

Reynolds JJR5000 series all-digital intelligent AC motor soft starter adopts power electronics technology, microprocessor technology and modern control theory technology, which is a new type of starting equipment at the current level. This product can limit the starting current of the asynchronous motor when it starts, and is widely used in fans, ...

The selection of the acceleration form and deceleration form of the inverter is also called the selection of acceleration and deceleration curves. Generally, there are several forms of inverter, such as linear, S-shaped, semi-S-shaped, etc., and the characteristics and uses of each form are as follows. 1. Linear form The form makes the inverter ...

As an electronic electric, the inverter itself also consumes electricity (about 3-5% of the additional power). A 1.5 hp air conditioner consumes 20-30W of electricity, which is equivalent to the length of a lamp. The inverter works under the power frequency and has the function of saving electricity, which is practical. But the conditions are: At the top of the list, great success ...
