Hi,
even if you did have the encoder set to a count of 17500 then the pulse rate would be:
17500 X 3000 /60=875kHz, thats low RF frequency, good luck trying to signal your drive!

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,
kool, the motor tuning looks good. Now double and triple check your speed rate override. I suspect
you have overide in action which is also affecting the rapids.

I would go back to P1-46 =2500

Now MDI:
G0 x500
x0
x500
x0

What speed is the motor doing approx?

This is because you can't get Mach/ESS to produce a 114 kHz pulse stream. Why not...is the real question.

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?

Don't know just yet, it is of secondary importance at the moment. I believe what is happening is that Mach/ESS/BoB  is struggling to signal your servo driver.

What BoB are you using? Can you post the manual for it?

What I'm thinking it that the BoB may have slow speed optoisolators as outputs and may well not be fast enough. Another possibility is that the BoB may have
a 3.3V or 5V output whereas your driver may be expecting 24V inputs. A third possibility is that the BoB may have active low outputs say whereas the driver inputs are
active high say.

We are going to need documentation and good documentation at that to diagnose this. I believe that all the settings in the drive are either correct or close enough
for the moment. We are now looking for an issue with Mach/ESS/BoB.

Do you have or have access to an oscilloscope?

Hi,
just noticed a small detail with the motor tuning, the steps per is 587 in the pic and they should be 571. Small detail, its not whats stopping it from working.
When we do get it going then you'll want it accurate.

Hi,
if you are using a pretty standard BoB then you'll use diagram C3-1 on page 3-30. Note your BoB will require standing 24V at open collector.

Really, REALLY need the info about your BoB.

Hi,
just re-read one of your early posts and I'm confused. Do you have a Warp9TD EthernetSmoothStepper or not? That HM4...whatever is not a BoB that I can see, it
looks like a motion controller.

Isn't the 560000 mm/min kind of high value?
did you get 3200 from    560000/175?

from a post on the first side

From the above If I have a 10:1 Gear Box Then with 3200 rev/min I will get a actual 320 rev/min and every revolution at 175 mm I will end up with 56,000 mm/mi

ok i missed the 10:1 gearbox,sorry.

and 1 missed 4x on encoder

so we are here

17.5mm/rev Motor
Motor 3200U/min -> max Speed 56000mm/min -> 933.3mm/s

P1 -44 -> 1
P1 -45 -> 1
P1 -46 -> 4375

Motor Tuning
steps per -> 1000

without and electronic gearbox.

btw, what is your paramater P1-00


sorry for the confusing.
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.
