Configuration simoreg 6RB2030 siemens

John someone to help me.

John I have everything connected. the motor is running very, very slow. the encoder is working me. linuxcnc screen in this recording me servo movement.

linuxcnc activate when I give, I get the Following Error joint2 alarm.

I know this because my business is, but any help would be great. I think I have everything connected properly.

enable only a single actuator, as it is my first test with this.

and remove the encoder data when I get the same message, but sometimes the servomotor starts faster.


thanks in advance

And before tuning you need to make sure that you have negative feedback
That is that the analog output of the 7I77 drives the motor in the proper direction
to correct a position error, not make it larger (and runaway)

You do this by setting the following error large enough (say 1 inch or 25 mm)
that you can see what the drive is doing before it faults out with a following error

wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error

first of all ... I want to share that works ....!!!!

For God is wonderful ....! it will be trivial for you but for me it is a great achievement.

Thanks John, Andy, Peter .... have been very patient with me.

John, I'm from Barranquilla, Colombia. my native language is Spanish. I rely on google translator, so I guess sometimes things do not make sense for you.

Friends work ..! I succeed in controlling the servomotor.

I'm setting the machine in mm, so had problems all the examples I've seen are in inches. and all the despair I noticed measurement units.

The question now, where do I start for get the correct PID?

remember in milimeter




thanks

John, thanks for your answer.

I am confused with PID.

1. this moving me servomotors
2. for now I only moved the P to 120 but I have not managed to stop the motor oscillate and vibrate a little.
3. the servomotors are hot.
4. servomotors move the positive and negative. (not as steady as it should be)
5. speak in a reply ZERO POT, see my Servo has one. as I adjust that, you had to move some "switch" your siemens servo?
6. Any other advice, how could configure PID.


thanks

Did you read BigJohnTs tuning page link above?

It has good basic information for tuning velocity mode servos

Do not let you servos oscillate! its hard on the motors/drives and mechanical parts
oscillation probably means your P gain is too high
(I am assuming you only have P and FF1 at this point as you should)
