7I96 Encoder Spindle tuning

I have an optical encoder, with A+ B+ and Index that seems to be generating signals. 
I also have a SPINX board attached that is driving a digital pot to my motor speed control.

The SPINX seems to control the speed, but my motor should go from 0 to 1200 RPMs, 

What do I need to look at in the HAL watch to see what I need to possibly change? I know the encoder is not producing the right speed, nor is the SPINX driving to pot from 0-100%.

Can you post your hal/ini files?

Here are all my hal and ini files

So the basic setup looks OK:
PWM scale set to 1200 so you should get 0V
when the commanded spindle speed is 0,
and full scale (spinout=spin+) at a commanded
speed of 1200 RPM

Do you get these values?

The encoder scaling say 20 which would be correct for a
5 slot disk using quadrature (A and Is thsi what you have?
 

This is my decal, I think it is as you described. 

I have the SPINX to my 5v power supply. I think there is a jumper on the control board that needs to be switched to 5v power.

What RPM do you get if you connect your drive speed command signal to 5V?

Also a hand made encoder may have fairly dirty signals so it
might be worth looking at them with halscope and perhaps
setting the encoder up for slower signals and better filtering

 

I think the problem may be the board, I had to order some parts for it. It would explain what is happening I think. I'll update you when I fix the board and let you know. Thanks as always

I think the encoder is working, my issue is with the way my SPINX1 is wired. I think the pot should go from 0-7V, mine is peaking at about 2.5. I think this is because I have the SPINX1 ENA tied to my OUT0+ which is 5V. The instructions on the SPINX1 say to power the board is 5v pin 1 and 6. 

How can I wire it so that I can get the digital pot to be from 0-7v? What does pin2 GND on the SPINX1 go to? 

The analog output voltage is not related to the 5V supply
It is the voltage difference between SP- and SP+ times
the PWM duty cycle, so for example if you had +12V
on SP+ and 0V on SP- and a 50% duty cycle PWM,
you would get 6V (12V* 50%) out.

The SPINX1A ENA pin must be _low_ for the analog out
to work. So for example if you wanted SSR5 to enable
the analog out, you would connect SSR5A to SPINX1 /ENA
and SSR5B to 5V GND

I kind of get what you are saying, but I am lost.

I am not sure how to connect the SPINX1 to my 7i96 card, and if I have my voltage wrong feeding it somewhere.

In my hal file, I have:
loadrt hm2_eth board_ip="192.168.1.121" config="num_encoders=1 num_pwmgens=1 num_stepgens=4 sserial_port_0=0xxxxxxx"
setp [HMOT](CARD0).pwmgen.pwm_frequency 20000
setp [HMOT](CARD0).pwmgen.pdm_frequency 6000000
setp [HMOT](CARD0).watchdog.timeout_ns 5000000

do the pdm and pwm both need to be set, or is one overriding the other one?

I am sorry, but I forgot a lot of my electronics knowledge a long while ago.
