Re: [Emc-users] 4th Axis (rotary axis)

[Marius Liebenberg]

Rick it is not a huge affair. Just specify in the ini file TYPE= ANGULAR 
for that axis

Its an axis Rick, and will need the same hardware as driver for whatever 
motor you have on it. Mine has a stepper motor, and the stanza in 
the .ini file looks like this:

[AXIS_3]
TYPE = ANGULAR
HOME = 0.0
MAX_VELOCITY = 50.0
MAX_ACCELERATION = 100.0
STEPGEN_MAXACCEL = 200.0
SCALE = 320.0
FERROR = 1
MIN_FERROR = .25
MIN_LIMIT = -1
MAX_LIMIT = 1
HOME_OFFSET = 0.0
HOME_SEARCH_VEL=0.0
#HOME_SEQUENCE=3
BACKLASH = 0.056

Driving it with a 2M542 driver, hooked as (from the .hal file)

setpstepgen.3.position-scale [AXIS_3]SCALE
setpstepgen.3.steplen   1
setpstepgen.3.stepspace 0
setpstepgen.3.dirhold   1
setpstepgen.3.dirsetup  1
setpstepgen.3.maxaccel  [AXIS_3]STEPGEN_MAXACCEL
net apos-cmdaxis.3.motor-pos-cmd => stepgen.3.position-cmd
net apos-fb stepgen.3.position-fb => axis.3.motor-pos-fb
net astep <=stepgen.3.step
net adir <= stepgen.3.dir
net aenable axis.3.amp-enable-out => stepgen.3.enable
...
net astep =>parport.0.pin-08-out
setpparport.0.pin-08-out-reset  1
net adir => parport.0.pin-09-out

You'll have to "home" it, even if its not plugged in at the time.

Be sure the cable to the motor is never plugged, or unplugged, without 
first turning off the driver power.  Drivers in general do not tolerate 
that at all well.

With a servo motor, I highly recommend jon's (Pico systems) PWM-Servo 
amplifier, its bulletproof and can handle up to 160 volts dc for the 
motor supply.  I've used it for a spindle motor driver twice now.

It can reverse the 1 hp motor of my G0704 from 2700 rpms fwd to 2700 rpms 
reverse in a small fraction over 1 second elapsed time. G33.1's are done 
before you can think about it for small taps.  Just make sure the chuck  
holding the tap is tightened to about 1 degree from broken, because if 
it slips, the tap is history.

I've been looking for a tap holder that grabs the square on the butt of 
the tap, but those things it seems all have a different, unique size.

Your table is apparently a couple thousand dollars better than mine, 
which has a brass thumbscrew for locking, and which doesn't begin to 
exert sufficient force to actually lock it.

I just zero mine along with the rest as theres no home switches on my 
toy. 2 more mouse clicks.

In that event, I'd tie those signals to control the hydraulics to those 
signals from motion that you quoted.  Hardware details are up to you, 
like how to control the valves that do the lock/unlock of the table.

Thats an open collector signal on pin 21?  Both on the same interface pin 
strongly suggests it is, so that it can be read as an input also.

Re: [Emc-users] 4th Axis (rotary axis)

[Rick Lair]

I was wondering more about these pins,

21  bit   IN  FALSE  axis.3.is-unlocked
21  bit   OUT FALSE  axis.3.unlock

The servo setup isn't the issue, I already have that stuff in my INI/HAL 
files, I was just wondering about those pins mentioned, if they will 
take care of making sure that the table is un-clamped at the right times 
for just positioning and for contouring. The table is hydraulically 
clamped and unclamped, with feedback limit switches for each position, 
and there is a home position switch.

That was going to be my next question, how to handle the homing sequence 
if we are not using the rotary axis. I was going to make up 2 
configurations, one with the rotary, one without.

I am going with Automation Direct for the servo and drive, 
http://www.automationdirect.com/adc/Shopping/Catalog/Motion_Control/Servo_Systems/Medium_Inertia_(1KW_-_3KW)_Servo_Systems/3KW_Servo_System_(Med_Inertia)/SVA-2300
 
. Using the servo with no brake.

To each his own,,,

The servo and drive will be here Tuesday, so it will be busy busy after 
that, we have a job coming in already, that requires the 4th axis.

Always Fun ;)

And the cabinet either of my mills is sitting on would be a Prince Albert 
can under that.  I see it does have hoisting hookbolts.

Its also, in well used condition, 22.5 times what I paid for my POJ, a 
decade back.

Looks like fun though.

[Emc-users] 4th Axis (rotary axis)

[Rick Lair]

Hello Guys,

Does anyone know in the documentation where to get any info on setting 
up my rotary axis, I can't find any thing in the manuals on how to get 
it connected properly, without doing a bunch of excess programming.
