Yaskawa inverter maintenance method

Yaskawa servo motor, also known as YASKAWA Yaskawa servo motor, is an automatic control system, which can control the position, orientation, status and other outputs of the target, and can change with the change of the target input value (or given value). It can be divided into AC servo motor and DC servo motor ...

There are two types of inverter overload faults: 1. If there is a problem with the load, it is a problem with the motor, such as the lack of oil in the bearing, the damage to the bearing, the burning of the winding, etc., and there is a situation that the power of the motor is small, and it is more difficult to drag the load. 2. It is the inverter ...

11. Robot jitter? Diagnostic process: Due to the difference between the jitter area and the amount of jitter, the diagnosis of jitter becomes a difficulty. At this stage, the diagnostic method is to replace the amplifier, replace the motor, and replace the reducer one by one. Improvement method: ...

The robot perception system transforms various internal state information and environmental information of the robot from signals to data and information that can be understood and applied by the robot itself or between robots, in addition to the need to perceive mechanical quantities related to its own working state, such as displacement, velocity, acceleration, force and force.

1 Disadvantages of choosing too high a voltage level Choosing too high a voltage level results in too high an investment and a long payback period. With the increase of the voltage level, the insulation of the motor must be improved, so that the price of the motor increases. The increase of the voltage level increases the number of series connections of power semiconductor devices in the inverter, ...

As we all know, the traditional material removal work is done manually, the cost is high, the efficiency is low, the accuracy of the parts is greatly affected by the manual, and the safety of workers is not effectively guaranteed, so what can be done to effectively solve these problems? Today, I will take you to understand the machine ...

First, the wiring of the main circuit 1. The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal (U, V, W) of the inverter, otherwise the inverter will be damaged. After wiring, the fragmented wires must be cleaned, and the fragmented wires may cause abnormalities. ...

It is composed of several parts, such as the main circuit, the power supply circuit, the IPM drive and protection circuit, and the cooling fan. Its structure is mostly in the form of units or modulars. Due to the incorrect use method or unreasonable setting environment, it will easily cause the inverter to malfunction and malfunction, or can not meet the expected ...

There are three types of general speed measurement methods: M method, T method, and M/T method. 1. M Method: (1) M method: open a time window, count the number of encoder pulses in this time window, the faster the speed, of course, the more pulses are counted for the time window. (2) Angular velocity ...

1. When the oscilloscope checks the current monitoring output of the driver, it is found that it is all noise and cannot be read; Cause of failure: The current monitoring output is not isolated from the AC power supply (transformer). Solution: It can be detected and observed with a DC voltmeter. 2. Motor ...

The fault codes of Yaskawa inverters are as follows: OC overcurrent; PG wiring is disconnected or wiring is incorrect; GF output ground fault ground short circuit ; PUF fuse blowing fuse blowing ; OV Main circuit overvoltage Main circuit overvoltage ...

1. Due to the soft material of the bolt material inside the Yaskawa inverter, if the tool is matched with a large error, it is easy to cause damage to the bolt head, it is recommended to equip the maintenance personnel with special tools of imported or joint venture brands. 2. The electrolytic capacitor and heat sink are made of aluminum alloy.

1. The acceleration/deceleration time constant is too small. Increase the acceleration/deceleration time constant. 2. The torque limit value set by the controller is too small. Increase the torque limit value. 3. The motor cannot start due to the insufficient torque caused by the drop in power supply voltage. 4. Check the power capacity. ...

1. Serial processing structure The so-called serial processing structure means that the control algorithm of the robot is processed by the serial machine, for this type of controller, from the computer structure, control mode to divide, and can be divided into the following: 1. Single CPU structure, centralized control mode ...

1. Failure of mechanical system (1) The common fault phenomena and causes of mechanical systems are as follows 1. Due to poor lubrication or lubrication system failure, the rotating parts of the parts are seriously heated and worn or the shaft is held, resulting in the destruction of the parts of the rolling or sliding parts. 2 ...

In the process of using various electrical and electronic equipment such as Yaskawa inverters, drives, etc., in addition to strict product related instructions to operate, in order to reduce the maintenance probability of Yaskawa inverters, it is also necessary to do a good job of correct maintenance and maintenance, which is also conducive to reducing the probability of maintenance, thereby reducing the ...

Yaskawa EPX2050 robots are often used in the automotive and other industrial painting fields to complete a variety of spraying operations, but long-term operations require the use of robot protective clothing to protect them. The following is a brief introduction to how Yaskawa EPX2050 spraying protective clothing is customized. Yaskawa EPX205 ...

There are three main burning methods for common Yaskawa robot servo motors: overload, phase loss, and short circuit. 1. Overload: Open the servo motor of the industrial robot to observe. The color of the entire winding wire pack has become dark and black, the end strap is cracked, and the serious phase insulation and notch insulation are due to overheating.

Yaskawa Electric recently announced that its soft starter processing plant in Shanghai has resumed production since February 18. So far, the three processing plants of this Japanese-funded processing and manufacturing company in China have been fully opened. Last week, Yaskawa Electric in China processed two other ...

1 Introduction Over the years, Yaskawa has accumulated very rich experience in the petroleum industry, such as G7/P7/F7/G5/P5/G5HHP/VS and other different series of inverters have been widely used in OEMs, the main fields are centrifugal separators, pumps, fans, transportation equipment ...
