The difference between inverter motor and ordinary motor - Reynolds

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 ...

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 ...

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 ...

When it is required to wiring outside the frequency conversion cabinet, it is generally necessary to use the conduit for wiring, which requires suitable mechanical pressure and unsuitable mechanical damage, moisture-proof and corrosion-resistant. Conduits include the following two wiring methods: 1. Kim ...

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. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reasons for this shortcoming are theoretically expounded and stated as follows. Depend on...

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) ...

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 ...

How to use a multimeter to measure the quality of the inverter, it needs to be noted that for personal safety, it is necessary to ensure that the machine is powered off, and remove the inverter input power line R, S, T and output line U, V, W before operation! First of all, the multimeter is hit to the "secondary pipe" file, and then through the multimeter ...

Overload can be different Servo drives generally have 3 times the overload ability, which can be used to overcome the inertial moment of the inertial load at the moment of start-up, while the frequency converter generally allows 1.5 times the overload. Handling precision Servo control ...

Low-voltage air circuit breaker, also known as active air switch or air switch, belongs to the switch electrical appliance, is used when the circuit is overloaded, short circuit and undervoltage can actively break the circuit of the electrical appliances, can also be used as infrequent start of the motor or opening and closing circuit, low-voltage air circuit breaker has an all-round circuit breaker ...

The following faults may be encountered during the use of the inverter, please refer to the following methods for simple fault analysis: 1. No manifestation at power-on: 1) Use a multimeter to check whether the input power supply of the inverter is consistent with the rated voltage of the inverter, and check the cleaning problem. 2） ...

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 ...

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.

Because the inverter and servo are different in performance and function, and the use is not very different, it is not possible: 1) In the case of speed control and torque control, the general frequency converter is not very high, and there are also frequency converters that are used to react signals in the upper position to form a closed loop.

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.

1. Test preparation: 1. It is necessary to remove all power switches before powering on the PLC control cabinet or IO cabinet. 2. It is necessary to completely cut off the connection between the PLC or DCS card and the outside. All front adapters are to be loosened and raised. 3. Check the power terminal wires and connectors.

The top failure modes of mechanical parts: Failure: The mechanical part cannot complete its normal function within the planning and booking period and under the regular conditions. Ways in which mechanical parts fail: overall cracking, plastic deformation, corrosion, abrasion, gluing, and touch exhaustion General ...
