hi Craig

thanks a million for your replies.

attached are prints of my Parameters.
I am sending them in 2 versions in case you may have any difficulty opening them up.
Also on the values of
P1-44
P1-45
I set them as your suggestions to the same number, and currently is set at 1600, which is only an experiment. By the way for these values,
What difference are between setting them a high value like 1600 vs. a low value such as 10 or 16?
I also noticed that the default value for them are 16, and 10

regards

Hi,
those two parameters are numerator and denominator ie a fraction.

For instance 10/16 is exactly the same as 1000/1600 or 5/8. In this case you don't want any gearing so the fraction should be equal to 1 so:
1/1 or 10/10 or 16/16 or 64/64, I don't care which and, except going to extremes, neither does the drive.

Please make sure parameter P1-46 is 2500 and please post a screenshot of your motor tuning page.

Hi Craig

Have you looked at my parameters that i had sent you in my 2 previous replies?

What is your opinion about them?

as I said before with If i set the values of numerator and denominator to the same value like 16, and as you can see the value of P1-46 = 2500 already, but

The Motor shafts moves very slowly some thing like 1 rev/sec,

I think the problem is some where among the other parameters, do you have any recommendation that which parameters do i need to change

in order to get better or higher RPM?

regards

Hi,
no I see nothing obvious so far. Can you post a screen pic of your motor tuning page?

175mm/rev Motor
Motor 3200U/min -> max Speed 560000mm/min -> 9333mm/s

P1 -44 -> 1
P1 -45 -> 1
P1 -46 -> 17500

Motor Tuning
steps per -> 100
velocity -> what ever your machine can handle before flying away
accelereation -> what ever your 750W Motor can handle with this big mechanikal Resolution(will be imho nearly nothing)

i am sure one of the given Parameters (imho 175mm/rev) is wrong.

Hi,

P1 -46 -> 17500

Wrong, this is the ppr NOT the encoder count. If you truly wish 17500 as encoder count the parameter
must be 17500/4=4375/
