How to set up a manuel gear change?

Hello.

On my mill i need to change the gears manual.

There is a lever with 3 positions, 1, 2 and 0.
On 1 I have a gear ratio from 1:5.57, on 2 it is 1:1.
If the lever is on 0, the Spindel is locked.
The lever is queried with 3 switches, S1, S2 and S3.
On Position 0 S1=1 S2=0 S3=0.
On position 1 S1=1 S2=0 S3=1
On Position 3 S1=0 S2=0 S3=1.
0=open switch, 1=closed switch.

S2 will be 1, if the lever is between 1,2, or 0 and the gears are not fully engaged.

The Spindel is controlles by a VFD.

My general Setup is a 5i20, a 7i33 for X,Y.Z, (later I will add a 4th axis), and a 7i37 for in- and outputs.
The VFD is controlles by a SpinX1 Card on P3 with pwmgen.04 to turn it on/off, set RPM and CW/CCW.

But how can I implement the manual gear box?
I want also to wire up a proximity sensor to the spindel to get a RPM feedback. The Sensor operates at 24V an can handel 1kHz, so I want to wire it to the 5i37?

Best regards
Marcel

Hello Andy,

the Spindel I drive by this:From there, it goes from the outputs of the 5i20 to the SpinX1, witch controlles the VFD, with 0-10V for RPM, an 2 Inputs for CW/CCW.

OK, will give it a try.
But where I define the 3 switches from the lever,
and what do you mean with
converting the switch positions to binary:
P0 = 1
P1 = 5
P2 = 4
All others = invalid

Best regards

OK,

I have written the code from your first post in my .hal file.
But I get an Error,
"PIN speed-raw motion.spindle-speed-out-rpm-abs does not exist"

Best regards
Marcel

OK, got it.
Now I need to conect the inputs of the 3 switches to switch1 - switch3
net switch1 mux8.0.sel0
net switch2 mux8.0.sel1
net switch3 mux8.0.sel2
Is this correct?

Thanks for your help,
Marcel
