hello tronicgr
with the link you give me, I searched on the internet and I found a lot of editing:
http://www.sonelec-musique.com/electron ... n_001.html
(sorry its french, but you can change with google )
they use this assembly to convert the PWM output in proportional variable from 0 to 10v.
that is what we need! cool.
he said that the change is proportional to %. 99%= 9,9V

(google traduction:
This project allows to convert a PWM signal (PWM) in a voltage whose value is proportional to the duty cycle of PWM signal. If the PWM signal has a duty cycle of 1%, the generated voltage is 0.1 V. If the PWM signal has a duty cycle of 99%, the generated voltage is 9.9 V. It is a montage that produces the opposite effect of my dimmer light 005, which for its part produces a PWM signal whose duty cycle depends on tension. The linearity of the PWM converter / voltage is relatively good, a PWM signal duty cycle of 35% produces a voltage of about 3.5V, and a PWM signal duty cycle of 75% produces a voltage in the range of 7.5 V. The frequency (fixed) of the PWM signal can be between 200 Hz and 20 KHz.)

you had already tested with the Velleman card?
I'll try editing, time to assemble the components and assemble the map.

Hi Riton,

Wow how did you find that? I was searching for that long time now. I ended making my own circuit by lots of study on amplifiers and many experiments!

I don't own K8055, but the circuit was tested successfully by Monast these days on his pneumatic BIKE simulator (using Proportional control valves)

Thanks! :thbup:

Regards, Thanos

I ordered the component to make the card (of my link,) I will send at SCOOTT to the test.
if it good, somes people in the forum can be interested to use, and test to.
I will soon begin my platform as his own with gear motor industry is really cool!
had you seen Scott video? and yet it still manages not speed!
it's terrible!
good works!

@scottlolo89

Have you been able to get the K8055 working proportional so far?

yes

my programme x-sim2 is for k8055

(direction ouptut digital )

(left right) bit 1 bit 2 bit for axe X input analogue 1 (potentiometre for position x )
(up down) bit 3 bit 4 bit for axe Y input analogue 2 (potentiometre for position y )

(the speed ouptut analogue no pwm)

( left and right ) analogue 1 for axe X no input analogue 1(no potentiometre)

(up and down) analogue 2 for axe Y no input analogue 2 (no potentiometre)

the variateur freqency reglage no 0/10 v yes 0/5 v

at this time scottlolo and me ,using the speed effect information to speed information, but it is not good!

how in the force profiler i can send a real speed information on the anolog output DAC1 and DAC2?
hox do you send speed in profiler with snc5?
what effect do you use to forward, to send or give speed?
thanks
