Hi there

I have not been able to go back to my supplier, I will get hold of them tomorrow.

by the way I was wondering that I think this pulse frequency starts from my lap top, Please correct me if I am wrong?

If that is the case and It basically Generates fro my Lap Top and Mach3, Could it be the case that my lap top is incapable of producing high frequencies?

Hi Craig

I was just wondering, that Mach3's Diagnostic Tab/Page doesn't have that Capability to check for frequency? It seems to me that It does have.

also on Mach3's Port&Pin Dialog it has a Encoder/MPG's Tab, How about the values of (Counts/U   and   Velocity), Do I need to modify these values.

I have not done a detail readings on these items as of yet.

I am really serious to get to the bottom of this issue, so I can go back to my Supplier in order to get refund or replace it to a better one.

Hi there

On the  issue of oscilloscope test, Could you explain briefly how can it be done? If you have clip on it would be great. my electrical ability is not my best part.

Hi Craig

Well that is a bad news, but good to know the cause of the problem, On my alternatives that you mentioned on my first one, what do I need to do? could you explain?

also can i add a BOB to my system in order to compensate for my short coming?

Hi there

Well Craig, you are pointing at an interesting issue here, attached is a picture of my Motion card, and there isn't any other BOB involved

in my system, all I have is a lap top with Win7, an ADAA - B2 Driver, 750 delta motor, Motion Card HM-LAN-4axis - and a 24 V, 10 Amp Power supply, and the ac power to my Motor.

also how about my LAN Card and/or it's settings in my Lap Top? Do I need to do some settings in my Mach3

Hi there

I am back at 2500, and I tried the MDI Moves. I do not know what could I find out from these moves. Basicly It appears that Speed is always the same some thing less than a 1 Rev/sec.

But as I increase the Steps per unit in Motor tuning Dialog to some thing like 1200 the speed Increases to about 2 rev/sec.

But it appears that there is a ceiling on this, and when I try to double the Steps per unit to value like 2400 then in the Motor Tuning dialog Box the speed drops

Automatically and no mater if I try i can not increase it much more.

S/U=600  speed 10000 mm/min I can Increase the speed to 20000 mm/min and actually the shaft rev/sec doubles, but apparently I can not increase the speed to more than 23000 mm/min

S/U =1200 at the same speed of 10000 mm/min the actual speed of the shaft of the motor Doubles to 2 rev/sec , But then In mach3 Motor Tuning I can not increase the speed to more than 1141 mm/min.

I should mention that presently I have not mounted my Gearbox to the motor, and motor is moving with out the gear box, but i am planing to use this 10:1 gearbox in actual run.

Finally what parameter sets the speed over ride in Delta Driver?

Hi there

Thanks for your replies

I tried the following:

P1 -44 = 1
P1 -45 = 1
P1 -46 = 17500                      also P1-46 = 4375

But nothing seems to Increase my speed, with all the above parameter settings, The speed remains sort of unchanged, and low some thing like 1 rev/sec

So far it appears the only thing that significantly Increase the speed is when P1-44 is about over 10 time the value of P1-45

attached is a pic. of my Motor Tuning

Also TPS:
How and where did you get these values  (Motor 3200U/min -> max Speed 560000mm/min )
Isn't the 560000 mm/min kind of high value?
did you get 3200 from    560000/175?

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?

Hi Craig

also the attached text file is the list of parameters that Have been changed Vs default ones,
I thought it might be helpful

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
