[1] Yaskawa 5 series 1KW drive on telegram 030 what is the reason?
When you power on, it will display 030, check the manual to explain: the main circuit is abnormal in various detection data, and there is no problem with the main circuit module after checking.
Is there a motherboard can be swapped to try,If not, you can change the 7860 optocoupler,I met one before is occasionally reported 030,But after a power failure and restart a few times, it will not be reported,Later, the overload warning is packed,Detection 7860 is also good,But if you change 7860, you won't call the police。
【2】Yaskawa drive maintenance order?
1. The fault of the servo drive first looks at the reported fault code and the fault record, so as to roughly judge the fault range of the servo drive.
2. Measure the voltage signal and on-off signal according to the fault phenomenon.
3. Common encoder faults, overcurrent faults, overvoltage faults, transistor dynamic faults, communication faults, etc.
4. Measure the quality of IGBT and brake resistance, whether the control line is loose, ignition marks, whether the encoder line is loose and whether it can be counted normally.
[3] Yaskawa servo alarm code A810?
A: A.810 A.81 Encoder Backup Encoder's power supply is completely depleted and the location data is cleared.
[4] The customer reacted that the Yaskawa server was powered on and reported C90, what is the reason?
Answer: C90 is the encoder communication failure, detect the connecting line. Swap the driver under the test and make sure it is not a problem with the line, then it must be the driver who asked.
[5] How to solve the alarm of Yaskawa servo drive 840?
Answer:
1. First of all, when the oscilloscope checks the current monitoring output of the driver, it is found that it is all noise and cannot be read, and it can be detected and observed with a DC voltmeter.
2. Then the motor runs faster in one direction than the other because the phase of the brushless motor is wrong. To detect or isolate the correct phase. When not used for testing, the test/deviation switch hits the test position.
[6] What does Yaskawa servo drive report 910 mean?
A: 910 alarm.
1. The encoder is disconnected or the contact is not enough.
2. The servo drive itself is faulty.
3. Caused by interference.
4. Servo motor encoder feedback unit failure.
[7] What does Yaskawa servo drive alarm code A91 mean?
A: A.910: Overload. (This is the warning display before the overload (A.710 or A.720) alarm is about to be reached.) If it continues to run, there is a chance that an alarm will occur. ); A.710 Overload (Instantaneous Maximum Load) and A.720 Overload (Continuous Maximum Load) were operated continuously at torques exceeding the rated value.
[8] Yaskawa SGDB power on A30 alarm?
Q: I use servo drive SGDB-30ADG servo motor SGMG-30AABB drive nominal 3 phase 200V ...
Answer: Don't connect it like that, the general detection circuit is on the 1 and 3 items, that is, the R and T items, you will connect L, N, and only connect these two items to see the S end empty to try.
[9] What does Yaskawa servo alarm AF5 mean?
A: Yaskawa servo alarm AF5 refers to check the motor power line, short circuit or broken wire. There are two possibilities for the AF5 alarm fault in the Yaskawa servo: it occurs when the control power supply is put in, then it is caused by the fault of the servo unit circuit board, and the servo unit needs to be replaced.
