Subject: [Emc-users] question for Peter C. W.
Greetings Peter;
Where on the 7i76, does pwmgen.00 of the 5i25 come out on?
Normally, nowhere, standard 7I76 firmware doesnt use a PWMgen for its analog
output, its part of the field I/O sserial remote. Its control pins/parameters
would be:
pins:
hm2_5i25.0.7i76.0.0.spindir # direction output
hm2_5i25.0.7i76.0.0.spinena # high to enable ENA pin and Analog out
hm2_5i25.0.7i76.0.0.spinout # analog value (positive only)
parameters:
hm2_5i25.0.7i76.0.0.spinout-scalemax # sets scaling of analog value
hm2_5i25.0.7i76.0.0.spinout-minlim # sets minimum analog value, typically 0
hm2_5i25.0.7i76.0.0.spinout-maxlim # sets maximum analog value, typically
same as scalemax = max RPM
Can I hal route the pwmgen.00 to the spindle pins on the 7i76 if not already
there? I'm putting a 3 phase stepper/servo, driving a 5/1 worm as an A drive
on my GO704. That means pwmgen.01 had to go, which I was using to run the
spindle cuz I needed the stepgen-4 outputs that are overriding stepgen4 when
2 pwmgens are loaded, Now I need that stepgen-4 for this A drive.
Cheers, Gene Heskett.
