HAL question

I need another help please.

my drive spindle,

requires three control signals. +. Analog signal of 0 +-10volts.

signals:

run
stop
DB: dynamic brake

to operate the DC motor, must have supply 120 VAC. by stop and DB.
linuxcnc spindle sends signal on
must send the analog signal, and must send 120 volts to RUN
To stop the machine I remove the DB signal and that signal must turn activate a solenoid that is applying the brake.

signals would be:


in HAL

  output

net spindle-on <= hm2_5i25.0.7i77.0.0.output-00
net spindle-brake <= hm2_5i25.0.7i77.0.0.inverter_output-01
net spindle-stop <= hm2_5i25.0.7i77.0.0.inverter_output-02



net spindle-on <= motion.spindle-on
net spindle-brake <= motion.spindle-brake
net spindle-stop <= halui.stop.manual


This would work.

Another question.

Because when I give S10 M3. 10volts gives me the voltage at the analog output of the spindle.

Something I noticed is that I say this in RPS.

That will have something to do?

Thanks for your answer.

Wonder that sometimes things are silly. sorry.

my spindle rotates up to 4000 rpm



MDI S10 M3 ===> analog output (spindle) = 10 VDC
MDI S1 M3 ===> analog output (spindle) = 1 VDC
MDI S4000 M3 ===> analog output (spindle) = 10VDC

I understand that I must give S100 M3 = 0.25 VDC??


Because with "S10 M3" spindle = 10VDC analog output?

must be bad.

thanks

#********************
# Spindle
#********************
[SPINDLE_9]
ENCODER_SCALE = 1024
OUTPUT_SCALE = -10.0
MAX_VELOCITY = 4000.0
OUTPUT_MIN_LIMIT = -4000
OUTPUT_MAX_LIMIT = 4000

You should set the 7I77s analog out 5 (assuming spindle on 5 ) scale to 4000 so it will read directly in RPM

setp hm2_5i25.0.7i77.0.1.analogout5-maxlim 4000
setp hm2_5i25.0.7i77.0.1.analogout5-minlim -4000
setp hm2_5i25.0.7i77.0.1.analogout5-scalemax 4000

thanks... Without you, we would not be able alone.


I have the spindle control, thank God.

Right now I do it via external buttons.

But as I can do to control for outputs "7i64" (run, Stop) through HAL.

HAL as I can tell, the output is activated only when you press linuxcnc active. and spindle stop, turn off the output.

some examples would help.

thanks and sorry for all this trouble.

Note that ALL 120V I/O needs to go through your is 2IO4B SSR modules
(no 120V should be connected to Mesa equipment)

Peter, thanks for your answer.


I understand that I must use 2IO4B SSR modules.

but my question is how to configure or set HAL.

understand that I must connect:

Motion.spindle-on with a 7i64 output. to activate the relay and send the 120 volts at Terminal 32

but not how to do the opposite.

Motion.spindle-brake with 7i64 OUTPUT, turn off the relay, and remove the 120 volts at terminal 33, for spindle stop, and reset (Motion.spindle-on)

not if I understand, I hope yes.



thanks in advance.

If I understand you right you are asking how to have a relay control for stop and start.
One way is to connect mption.spindle-on to two outputs of the 7i64 and invert one of the outputs.
Then one output will be on when spindle-on is true while the other is off.
the opposite is true when spindle-on is false.

Hope that's what you meant.
