When debugging the inverter, it is necessary to pay attention to safety, comply with operating procedures, and protect the safety of equipment and personnel. For users who are not familiar with inverter commissioning, it is recommended to seek professional technical support or training.

The F08 fault code reported by the SEW inverter is a speed monitoring fault

The reasons for this failure are as follows: the speed controller or current controller (under VFC control without encoder) operates at the set limit value due to mechanical overload or phase failure of the power supply system and motor; The encoder is not properly connected or rotates in the wrong direction; The maximum speed under the VFC operating mode has been exceeded.

Troubleshooting measures: reduce the load; Increase the deceleration time setpoint (P501 or P503); Check the encoder connection and swap A and B in pairs if necessary; Check the encoder power supply; Check the current limit value; inspect the motor cables and motors; Appropriate prolongation of the oblique wave; Check the phase of the power supply system.

The external terminals of the inverter, RH, RM, RL are speed control terminals. The combination of these terminals allows for three-stage and seven-speed control. In addition, the redefinition of other terminals can also achieve fifteen-step speed control.

1. Three-speed operation.

The external terminals RH, RM, RL are the three-speed control end of the inverter, which controls the speed of the motor. By writing the PLC program to control the output signal, and then the PLC output signal respectively controls the RH, RM, RL terminals of the inverter or directly controls the separate on-off of the three speed control terminals, the high, medium and low speed control of the motor can be realized accordingly. The frequencies of the three speeds are set by the parameter , , respectively.

Summary. Hello dear, the inverter is a device used to control the speed of the AC motor, which can achieve precise control of the motor by adjusting the output frequency and voltage. The following are the general inverter adjustment steps:

Make sure the power supply and inverter are connected correctly and wired in accordance with the electrical safety code. Set the required parameters on the inverter panel, such as input voltage, output frequency, overload protection, etc. The specific parameter setting method may vary depending on the brand and model of inverter, and it is recommended to refer to the relevant instruction manual for operation.

Set the operating mode of the inverter to manual mode to ensure that the motor is not started automatically. According to the operation steps of the inverter, gradually increase the output frequency and voltage, and gradually increase the speed of the motor. Pay attention to the sound and vibration of the motor during the adjustment process to ensure the normal operation of the motor.

If further adjustment is required, other parameters can be adjusted according to actual needs, such as acceleration time, deceleration time, frequency hopping control, etc. After the adjustment is completed, the operating mode of the inverter can be switched to automatic mode to achieve automatic control.

After the adjustment is completed, the operating mode of the inverter can be switched to the automatic mode to achieve automatic control.

It depends on what you want to do with it, and the question is very vague.

Generally most of the parameter settings:

1. Control mode:

i.e. speed control, rotation control, PID control, or other means. After the control mode is adopted, static or dynamic identification is generally carried out according to the control accuracy.

2. Minimum operating frequency:

That is, the minimum speed of the motor operation, when the motor runs at low speed and wide bicycle, its heat dissipation performance is very poor, and the motor runs at low speed for a long time, which will cause the motor to burn out. In addition, at low speeds, the current in the cable will also increase, which will also cause the cable to heat up.

3. Maximum operating frequency:

The maximum frequency of the general inverter is 60Hz, and some even reach 400Hz, and the high frequency will make the motor run at high speed, which is for the ordinary motor, its bearing can not run beyond the rated speed for a long time, and whether the rotor of the motor can withstand such centrifugal force.

4. Carrier frequency:

The higher the carrier frequency setting, the larger the higher harmonic component, which is closely related to the length of the cable, the heating of the motor, the heating of the cable and the heating of the inverter.

5. Motor parameters:

The inverter sets the power, current, voltage, speed, and maximum frequency of the motor in the parameters, which can be obtained directly from the motor nameplate.

6. Frequency hopping: At a certain frequency point, resonance may occur, especially when the whole device is relatively high; When controlling the compressor, it is necessary to avoid the surge point of the compression machine.

The commissioning of the inverter needs to be carried out according to the specific model and application scenario. In general, the steps to debug the inverter are as follows:

Confirm the power supply: The power supply of the inverter needs to be consistent with the power supply of the motor, and it is necessary to check whether the power supply meets the rated voltage and frequency of the inverter.

Wiring confirmation: Wiring according to the wiring diagram of the inverter to confirm whether the wiring is correct. In particular, the U, V, and W three-phase wires of the motor and the U, V, and W three-phase wires of the inverter need to be connected correctly.

Adjust parameters: Set the operating parameters of the inverter through the vibrato parameter setting interface of the inverter, including the maximum output frequency, the minimum output frequency, and the fuel load protection parameters of the over/hole hole.

Run test: Connect the output port of the inverter to the motor for operation test. By monitoring the output frequency, voltage, current and other parameters of the inverter, the normal operation of the motor is ensured.

Adjust the parameters: According to the results of the running test, make the necessary parameter adjustments until the best running effect is achieved.

It should be noted that commissioning the inverter requires certain electrical knowledge and experience, and at the same time, it is necessary to comply with relevant safety regulations to ensure the safety of the commissioning process. If you don't have the relevant technical knowledge, it is recommended to ask a professional electrical engineer for commissioning.

The speed regulation of the inverter is achieved by adjusting the frequency and voltage of the inverter, and the specific steps are as follows:1Connect the power supply and connect the PLC to the inverter.

Make sure the connection is correct and follow the correct procedure. 2.Adjust the parameters of the inverter.

The inverter usually has multiple parameters that need to be set, including frequency, voltage, operation mode, starting acceleration, etc., to ensure that these parameters are set correctly. 3.Start the speed regulation.

Speed adjustment can be done either manually or automatically. The manual method requires selecting the motor speed first, and then gradually adjusting the frequency and voltage of the inverter until the desired speed is reached. The automatic speed adjustment function will automatically adjust the motor speed to a specified value.

4.Monitor the slow running status of the motor section. After the speed regulation starts, the motor operation status needs to be monitored to ensure that the motor runs at a smooth speed, and the speed will not exceed the rated value, and there will be no other abnormal phenomena.

5.Complete the speed regulation. After completing the motor speed regulation, you need to verify the speed regulation effect and check whether the equipment is operating normally.

If a problem is found, it needs to be adjusted in time until the desired effect is achieved. In short, the speed regulation of the inverter needs to be adjusted according to the specific situation, including parameter setting, frequency and voltage regulation, and monitoring the running status of the motor. It is necessary to have a certain understanding of the equipment, and the complex inverter speed control equipment needs to be debugged by professional engineers.
