Misunderstanding of inverter selection - Reynolds

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 ...

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 ...

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

Because inverters are widely used, there are many differences in the corresponding types and specifications. We are broadly divided into two categories: voltage and current. The current type of inverter products is characterized by the use of a large inductor as the energy storage link in the middle DC link, and the reactive power will be buffered by this inductor. ...

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 ...

A brief introduction to the progress of the inverter in terms of torque: This function adds the output voltage of the inverter so that the output torque of the motor is proportional to the square of the voltage, so as to improve the output torque of the motor. Improve the skill of insufficient torque at low speed output of the motor, and use the "vector manipulation" ...

In ancient times, there were ten major tortures, which made people unable to survive and die, and experienced the purgatory of the world; Today, there are ten "tortures" of inverters, and the same can make your inverters suffer. Let's follow the editor to find out which of the top ten "tortures" will make your inverter "worse than dead"! ...

1. The soft starter does not start and the fault-free code appears, perhaps because the control power supply is not connected, the solution is to check the power supply of the control power supply to see if the circuit connection is correct. 2. The motor starts when the motor announces a hum/no start signal, perhaps because of the thyristor/module ...

Single-phase current transmitter is a kind of electric power test substation developed for the power measurement of single-phase communication in motor experiments on the basis of motor experiment and testing technology research, in accordance with IEC and relevant national specifications for motor experiments. The use of advanced filtering technology, reasonable software algorithms, ...

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...

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 ...

The high-voltage inverter has been designed with the safety of the user in mind. However, due to the energy storage capacitor installed inside the power unit of the inverter, it may still carry a high voltage after disconnecting the power supply, and some parts generate a lot of heat, so contact is prohibited. When working on or near the inverter, please ...

1. Advanced technology: (PC or PLC) is used to make the equipment complete the intelligent constant pressure variable supply water supply according to the requirements of water supply and fire protection; 2. High efficiency and energy saving: the system can set the pressure according to the demand, and the system can actively adjust according to the set pressure.

Under the current production conditions, when the inverter is used to form an automatic control system for control, in many cases, it is necessary to choose PLC and inverter to match the use, such as bearing cleaning, packaging paper printing, PCB board production, etc. PLC ...

(1) Frequent starting, resulting in excessive temperature, causing overheating maintenance of soft starter. (The number of starts of the soft starter should be controlled to no more than 6 times per hour, especially for heavy loads) (2) During starting, ...

(1) The starting torque is large and the power factor is high. Because the power factor of the motor is related to the working frequency, the power factor under the power frequency power supply is much lower than that under the low-frequency power supply when the motor is running at low speed. The inverter can control the motor from low frequencies and ...

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 ...

Reynolds soft starter fault code Instantaneous stop -F 01 Instantaneous stop terminal 7 to terminal 10 open TOO LONG STARTING TIME -F 02 STARTING TIME IS TOO LOW AND THE STARTING TIME IS TOO LONG (GREATER THAN 60S) Overheating -F 03 Start too often, reduce the number of starts Input out of phase -F 04 ...

Voltage level: The voltage level should match the voltage level of the power supply and motor to ensure electrical safety and normal operation of the equipment. Current level: The current level should match the rated current of the motor to ensure electrical safety and normal operation of the equipment. Cable Specification: Cable ...

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 ...
