Spindle encoder wiring check

Hi
I'm busy connected a spindle encoder to my 7i76. Did I wired everything the right way?

black = GND
brown = +5VDC
green = 1ppr output
white = 360ppr output


I connected the wires to DB3

black -> Pin9 GND
brown -> Pin12 +5V
green -> Pin13 IDX+
white -> Ping7 ENCA+

That looks correct

You also need to set the encoder mode jumpers for single ended mode
(W4,W5,W6 in left hand position)

Thanks

Is it possible to configure this with PNCconfig?
With stepconf it's possible it seems. To configure a phase A and index

Ok I'm a bit further with the configuration.
I used PNCconfig.

HAL section
setp hm2_5i25.0.encoder.00.counter-mode 0
setp hm2_5i25.0.encoder.00.filter 1
setp hm2_5i25.0.encoder.00.index-invert 0
setp hm2_5i25.0.encoder.00.index-mask 0
setp hm2_5i25.0.encoder.00.index-mask-invert 0
setp hm2_5i25.0.encoder.00.scale [SPINDLE_9]ENCODER_SCALE

net spindle-revs <= hm2_5i25.0.encoder.00.position
net spindle-vel-fb-rps <= hm2_5i25.0.encoder.00.velocity
net spindle-index-enable <=> hm2_5i25.0.encoder.00.index-enable

Ini file
ENCODER_SCALE = 360.0

When I check with HALmeter and I turn the spindle the value goes up. So that's good I guess.

The scale is 360 in the ini file (it's a 360ppr encoder)
I think the index doesnt work? It doesnt change from False to true in the HAL meter

for "A" only encoders you need to set the encoder counter to up/down mode
setp hm2_5i25.0.encoder.00.counter-mode 1

After changing this, you may have to change the sign of the scale value if the count goes the wrong way

Often the index is too short to see with halmeter or halscope, so the way ti test it is to
set spindle-index-enable true and watch spindle-index-enable as you manual turn the spindle
it should go false when the index is detected (in just one place per rotation)

So with linuxCNC running, setup a halmeter to watch spindle-index-enable,
set spindle-index-enable true with:
halcmd sets spindle-index-enable true
and then rotate the spindle by hand as you watch spindle-index-enable with the halmeter

I checked with HALmeter
spindle-index-enable is true. When I turn the spindle manually it doesn't switch to false.

Phase A is working fine though.

When I check the encoder.00.count I get a - value. No matter which side I turn the spindle. Don't know if that's good?

I also don't fully understand how the scale is being calculated?
It asks for the pulses per revolution. It will multiply by 4 and that's the encoder scale.
The PPR is 360. But why does it multiply with 4 to calculate the encoder scale?
Do I need to fill in 90? 90 x 4 = 360

Yes, if you are not using quadrature ( A and B ) the scale should not be multiplied by 4
You also need to change the sign of the scale value so it counts up so if pncconf multiplies
by 4 you should enter -90.

Also at some point you are better off not using pncconf and just editing the hal file directly
pncconf is good for creating the basic structure of the configuration, but for anything beyond
the basics, you will need to edit the hal file by hand, and once you have done this you cannot use
pncconf again without losing your changes

Index and PhaseA is working!
I changed 360 to -360. And the pin: encoder.position (checked with halmeter) is counting upwards instead of negative.
All seems good I think?

I want to upgrade the encoder on my machine to a quadrature so I can do rigid tapping on my lathe.

Currently a rotary encoder is connected with a belt to the spindle.
Which kind of things I need to check for a new encoder? or does a quadrature encoder always got a index, a and b pulse?
