To be honest, the 466 alarm on the scene, nine out of ten times are the following cases, the set is particularly obvious.
* Replaced the
servo drive, but the parameters froze (this case is the most common)
This thing is really too common. For example, you replaced a new or dismantled servo amplifier, installed directly after the power, the results immediately reported 466. the reason is very simple, the new drive in the head of the parameters stored in the factory or on the home, with your original motor can not be numbered ah. System a comparison, found a stranger, directly pull the alarm.
The logic is exactly the same. As long as the motor is changed, the model has changed, the current specification has changed, but the parameters are still the same. The system looks, not right ah this who ah, report 466 no negotiation.
* Parameters are lost or have been tampered with.
Sometimes you did not move any hardware, but the parameters were cleared, or who slipped and changed a few numbers. When the system re-recognizes, it finds that the motor information in the record does not match the actual one, and reports 466 as usual.
* Mixing models that don't match at all
For example, the motor is α series, the drive is another specification, or the rated current difference is far. This situation is not a parameter problem, is a real mismatch, the system simply can not recognize.
* Repair the drive when changed inside the small module
Some people repair the drive is not the whole piece to change, but to change the side plate or the inside of the small module. These parts sometimes carry identification information, and it is possible to trigger the 466 after the replacement. It's a little more subtle, but it does happen.
How to press 466 quickly in the field, my own way of doing it.
Don't complicate the process, just do it in the order that you would actually do it. First, ask yourself: Have you moved anything recently? Have you changed drives? Changed the motor? Did you change the parameters? If the answer is "yes”, you're basically on the right track.
Directly run to the parameters to start. A lot of masters go up to do one thing - to change the parameter 2165 to 0. The essence of doing so is to tell the system: "you previously remembered that set of things are invalid, give me to re-recognize once again.” After the change, shut down and reboot, and in some cases the alarm is gone, so it's a snap.
If it's fine after the reboot, then it's done. If it still won't go away, then let's move on.
The next step is to get a little more serious about the model number. Copy down the model number on the ass of the motor, the model number on the side of the drive, and check the current rating to see if it's in the official Fanuc matching table. If you save a combination yourself, the system probably won't recognize it.
If you have a backup of the previous parameters in hand, it is the safest to restore them directly, which is much more reliable than adjusting them manually by yourself.
At this point is not, then we have to resign ourselves to fate - either the drive is not right, or the motor is not right, must be replaced with the right model. Don't take it on the chin, you can't take it on the chin if the system is fighting you. If you can't, you can find a professional team like
Songwei CNC.
Never mix 466 with any other servo alarms!
A lot of people can't tell the difference between these codes, so let's go through them briefly:
- 400: servo problem, wide range.
- 401: servo not ready, can't start.
- 466: the wrong combination, is a configuration problem.
So the root of 466 is "you've got the wrong one”, not "something's broken”.
