Index Home Delta A2 E is it possible?

Category: EtherCAT

Hi everyone, I'm new to the forum. I'm Italian and I'm using a translator.
I have a Delta A2 model E servo drive (EtherCAT).
I'd like to use Index Home, but I noticed that the CN1 connector on the drive is missing the OCZ signal output.
Is there another way to do Index Home?
For communication, I use Beckhoff EK1100, EL1859.
Thanks in advance.

I would choose a higher wattage/higher maximum voltage resistor

Is it possible to use stall force tolerance for z axis home and detecting the sheet metal in qtplasmac?  I will add a floating head and a z home switch if its not possible.

So at the beginning of the hal file
there is a commented out loadrt for the
abs function and later on an addf line
for that function that fails because
the function was never installed.

I suspect this is a bug in this pncconf
version when certain spindle functions are not
used. It turns out the the abs function
is never used, so simplest fix would be to delete
the addf abs.spindle line in the hal file.

#loadrt abs names=abs.spindle
#loadrt lowpass names=lowpass.spindle


addf hm2_5i25.0.read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pid.x.do-pid-calcs servo-thread
addf pid.y.do-pid-calcs servo-thread
addf pid.z.do-pid-calcs servo-thread
addf pid.a.do-pid-calcs servo-thread
addf pid.s.do-pid-calcs servo-thread
addf abs.spindle servo-thread
addf lowpass.spindle servo-thread

addf hm2_5i25.0.write servo-thread
setp hm2_5i25.0.dpll.01.timer-us -50
setp hm2_5i25.0.stepgen.timer-number 1

Edit:

Note that the same issue is there with the lowpass function.

I suspect these were added for some some spindle speed display
function, that was not used, and only 1/2 removed from the hal
file boilerplate
