Introduction and features of Reynolds soft starters

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. 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 ...

Assuming Icu=60KA, then when a faulty current of 60KA is generated in the line, the circuit breaker can safely cut off the circuit without abnormal conditions such as contact welding and blasting. Pay attention to the extreme breaking ...

1. The power and temperature rise of the motor Regardless of the method of the inverter, different degrees of harmonic voltage and current occur during operation, so that the motor runs under non-sinusoidal voltage and current. Rejection of material introduction, taking the sine wave PWM type inverter that is now widely used as an example, ...

Working environment In the actual application of inverters, most people install inverters directly in industrial sites in order to reduce costs. The job site generally has the problems of large dust, high temperature and high humidity, and in some occupations, there are also metal dust, corrosive gases and so on. There must be ...

First, select from the inverter "software". The reason why the factory chooses the inverter to work together with the fan is that it is hoped that the automation and intelligent design of the inverter technology can improve the speed regulation mode of the fan, and reduce the wasted energy consumption, which not only improves the wind efficiency.

Inverters are widely used in all walks of life, in a variety of applications, inverters will inevitably encounter rainy and humid climate, resulting in internal wetness, or accidentally into the water, in fact, as long as it is found in time, it can still be rescued. If it is in the unpowered state ...

The basic principle of vector control is to control the excitation current and torque current of the asynchronous motor according to the principle of magnetic field orientation through the measurement and control of the stator current vector of the asynchronous motor, and then achieve the purpose of controlling the torque of the asynchronous motor. Specifically, the stator of the asynchronous motor ...

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 ...

Recently, in the "2012 National Torch Program Project" issued by the Ministry of Science and Technology of the People's Republic of China, the "RNB6000 Frequency Conversion Governor" independently developed by Reynolds was included in the "2012 National Torch Program Project" with its domestic leading skills and efficient energy-saving conversion power.

1. If the bearing is in good continuous rotation condition, it will emit a low whining or humming sound. Sharp hissing, squeaking and other irregular sounds often indicate that the bearing is in a bad continuous rotation condition. The sharp squeaky noise can be due to the formation of an inappropriately smooth ...

1) Query and query fault phenomena. The fault phenomenon of the inverter is varied, for example, the same type of problem may have different problem phenomena, and different types of problems may have the same kind of problem, which brings difficulties to find the problem. However, the problem phenomenon is the fundamental basis for repairing the inverter ...

Precautions for low-voltage soft starters For cooling purposes, the soft starter must be installed in a straight direction. In order to ensure excellent heat dissipation, there should be room for the soft starter device. Main circuit selection ...

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.

The voltage waveform output by the inverter is only similar to a sine wave, but not a real sine wave, and its waveform contains a large number of harmonic components. As we all know, the higher harmonics will increase the output current of the inverter, causing the motor winding to heat up.

1. Problems of the inverter and the motor itself; After the motor has been used for a long time, it cannot be ruled out that the insulation function is not good, or the bearing is stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced in three phases, and the fixtures of the motor are loose.

1. Direct launch The universal inverter insists on starting at the beginning of the time according to the set starting frequency and starting frequency, and then accelerates to a given frequency according to the selected acceleration time Second, the speed of the tracking start Universal inverter ...

There are three types of fault signals for the inverter: (1) Excessive mechanical load: The primary feature of excessive load is that the motor heats up, and the operating current can be read from the display screen to find. The primary reason is that the load of the inverter is too large, and the acceleration and deceleration time and operation cycle time are too short; V/F ...

1. What are the factory parameters of inverter rehabilitation? 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, [motor leakage inductance reactance] is the specified sub...

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.
