The distance between the Reynolds frequency converter and the motor determines the cable and wiring method

Installing a variable-frequency drive (VFD) on the power frequency motor can complete the precise control and speed regulation of the motor, and improve the power and accuracy of the progressive motor. However, if it is not properly used and used, the following damages may occur: ...

Short-circuit maintenance is a function of equipment connected between the power supply and the load, which can effectively disconnect the short-circuit point from the power supply when the load side is short-circuited. If an equipment has a short-circuit maintenance function, it must have a certain short-circuit breaking ability; And a device with the ability to break in a short circuit ...

First, the inverter is not repaired and the power test is tested (1) Inverter repair test rectifier circuit At the two ends of the inverter to detect the internal DC power supply, P and N ends, adjust the multimeter to the resistance RX10 gear, the red watch pen is connected to the P end, and the black watch pen is connected to R, S, T, and there are tens of ohms under normal conditions.

In the repair of the inverter, we often hear about overpressure problems, but underpressure problems are also common problems encountered in the use of inverters. The reason is that the main circuit voltage is lower than the lower limit caused by the maintenance action or the damage of a rectifier bridge or the instantaneous power failure of the power grid, and the input is flat. Inverter after-sales ...

Motor soft starter is the primary selection of power electronics skills and microprocessing skills and modern control theory and design and production of advanced level of new engine equipment, motor soft starter mainly has anti-interference function, high reliability, multiple protection functions and other characteristics, according to these characteristics of electric ...

(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 ...

The acceleration time of the Reynolds inverter is the time required for the output frequency to rise from 0 to the high frequency, and the deceleration time is the time required to decrease from the high frequency to 0. Generally, the frequency converter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. The rise of the frequency setting must be limited when the motor accelerates.

1. Yaskawa inverter G5-G7 power correction: enter the menu and then return to 02-04 after A01=4 is the power data, and the factory voltage of rehabilitation has also changed after the change. 2. Sanken inverter IHF-IPF-SHF series: enter the CD900 parameter and enter 365 to confirm (change 2 times...

1. Clarification of the function of the control panel 1. FUN button; Press the FUN button to enter the settings menu F00; 2. Press and hold the up or down button to scroll to the code you need to set; 3. At this moment, press the FUN button to confirm, and adjust the entry parameters to the required value; 4. After the adjustment is completed, ...

Each type of servo motor has additional torque, maximum torque and servo motor inertia and other parameters in the standard items, each parameter and load torque and load inertia must have a relevant connection, the output torque of the servo motor should meet the requirements of the movement conditions of the load organization, such as the speed of the acceleration ...

After selecting the resistance value of the braking resistor, the power value of the braking resistor should be confirmed, and the selection of the braking resistor power is relatively cumbersome, and it is related to many factors. The instantaneous power consumed by the braking resistor is calculated according to the following formula: P instantaneous = ...

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、 ...

1. Select varieties according to the above series according to the purpose and requirements of use Note that the main circuit load type is strictly differentiated, whether it is DC or communication. The communication contactor is different from the DC contactor, and is only suitable for DC-1 to DC-5 loads when used for DC loads.

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.

a. Output frequency scale. The output frequency scale that can be controlled by the general inverter, the lowest starting frequency is generally 0.1Hz, and the highest frequency is different according to the functional indicators of the inverter, generally 400Hz, and some models are 650Hz. No matter how high the output frequency is, it depends on the scale of the high-frequency inverter. ...

Most of the applications of frequency converters (hereinafter referred to as -VFDs) are primarily due to the fact that VFDs can change the output frequency and thus change the speed of the motor. If the frequency of the VFD cannot be adjusted and no damage is found on the hardware, it can be considered that the maximum output torque of the VFD is less than the load progress torque ...

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 ...
