[10] Yaskawa servo back to the origin can not find the C phase pulse, Yaskawa servo drive and motor, using the travel switch + C phase back to zero mode, now the pressure on the switch deceleration can not find the C phase pulse, servo motor, drive, host computer, which fault is the most likely?
Answer: The servo motor rotates one rotation and only has a C-phase pulse, and it is at a fixed angle of the motor, so,
1. If the motor does not reverse after pressing the travel switch, it may encounter the mechanical limit, so that the C project pulse cannot be found.
2. If the motor is reversed after pressing the travel switch, it may be that the motor speed is too fast, or the crossover pulse setting is a problem.
[11] What is the topic of Yaskawa servo drive maintenance?
Easy to repair Yaskawa technical topic servo drive fault maintenance practical highlights, the topic mainly contains some common faults of servo drive, related maintenance experience and skills, the essence of servo drive, classic cases and video tutorials, etc.; And for the maintenance of the server, some experience and skills of ordinary maintenance are recorded.
[12] When the Shuyashikawa servo driver checked the current monitoring output of the driver with an oscilloscope, it was found that it was all noisy and the output waveform could not be read.
Answer. After the engineer eliminated it in many ways, it was found that the output terminal of the current monitoring was not isolated from the AC power supply, and the fault was removed after the isolation transformer was taken, and the waveform had an output, and it could also be directly detected and observed with a DC voltmeter to overcome the interference.
[13] What is the reason why the Yaskawa servo motor on an industrial equipment runs faster in one direction than the other.
Cause of failure: The phase of the brushless motor is wrong. Solution: Detect or find out the correct phase, when not used for testing, the test/deviation switch hits the test position, the test/deviation switch hits the deviation position'The position of the deviation potentiometer is incorrect, the treatment method: reset.
[14] An example of Yaskawa servo motor stall troubleshooting?
Answer, the test with the motor found that the cause of the failure: the polarity of the speed feedback is wrong, and the correct way to deal with it is
1. If possible, hit the position feedback polarity switch to another position. (Yes on some drives)
2. If you use a speed tester, switch the TACH+ and TACH- on the drive.
3. If you use an encoder, switch the ENCA and ENCB on the drive to the connection.
4. If you are in HALL speed mode, switch HALL-1 and HALL-3 on the drive, and then connect Motor-A and Motor-B.
At this point, the troubleshooting has been completed.
[15] How much is the maintenance price of Yaskawa servo drive?
The maintenance of servo drive depends on the specific fault, power, model is different, and the charge is different, depending on the charging standard of each maintenance company.
[16] Mitsubishi servo drive is currently a very widely used servo drive brand, from the general industrial control to the complex CNC system control has Mitsubishi, maintenance Mitsubishi engineers are also very many, so the maintenance price of Mitsubishi servo drive is not already very low, or standardized.
[17] Yaskawa 7 series only has a red dot, what is the problem of flashing light failure?
If the fan is broken, replace it.
[18] Yaskawa 7 series alarm A10, what is the cause and how to repair it?
This is Yaskawa's pain, just replace the fan.
