Please help -- Mesa 7I96S 24VDC Contactor Wiring

Hi,

Please help with how to wire a 24VDC contactor to the Mesa 7I96S to switch on a wood router from LinuxCNC.

I would like to switch a wood router from LinuxCNC. I have the below 24VDC contactor and flyback diode:

- Contactor: www.tropac.com.au/10-Pole-24VDC-Coil-5.5...Contactor-LS-Metasol

- Flyback diode: www.jaycar.com.au/diode-fr307-1000v-3a-d027-pack-10/p/ZR1052  

I've learned how contactor works. I have wired and able to switch on a Dremel grinder via this contactor.

I think this is how I should wire it:


Is it correct, please? 

Thank you and best regards,

That is correct.

Hi,

I have successfully tested this wiring out with LinuxCNC.

In the main .HAL file, the following lines were added:

[
net router-enable    <=   spindle.0.on
net router-enable    =>   hm2_7i96s.0.ssr.00.out-00
]

The command:

[
$ halcmd show pin | grep spindle
]

Lists spindle.0.on among other entries.

Then I used LinuxCNC to run this GCode (.ngc) file:

[
M3 S1000  ; Enable spindle
G4 P10    ; Wait 10 seconds
M5        ; Stop spindle
M2
]

It turns on the contactor coil, we will hear a click, then it gets the Dremel grinder to spins for 10 seconds, then it turn off the coil, we will hear a click again, the Dremel also stop running.

-- This Dremel grinder does not have no-start protection feature.

This is how I wire the contactor and the Dremel grinder:



Prior to trying out this contactor, all I have running is the X-Axis motor, so the HAL configuration is very basic.

Thank you and best regards,

...behai.
