Where do I get a power source for this relay ?
I have a SSR-25-DA. Input 3-32VDC

Why is it a bad way using 48v PS ?

Im concerned running a 120v neutral line around my mill.
Probably would have to use 12ga solid. Then enclose in a protective conduit of some type.

Should limit switches be tied in w/ a power supply ?

If I understand correctly, the above posted design has limit switches thru the Geck540.
If a switch is tripped, is sent thru the Gecko540 causing a stop to axis pin 1-4. Reset thru Mach3.

Which opens another ques. If an axis has hit a limit, how can you move it off the limit if there is an estop ?
I havnt tried this yet.

I have decided to use the Neg 48v PS thru my estop.
Im also tying in the Neg from Z-driver w/ estop.

Still trying to figure using Z limits in conjunction w/ Gecko540
From my initial post, Z is handled by a separate BOB and driver on port 2. Limits are NO, not NC .

Your Estop switch should disconnect the A/C mains power from the 48V power supply. Do not switch the 48Vdc supply with the E-Stop as this may damage the G540.

An example G540 wiring diagram Engineering Note EN010 can be found on this page;

Looks better than my drawing .  Thanks !

Hard time understanding this, is that a manual switch for the pin 10 enable ? Instead of running thru estop.

And... why the RL-04 48/240 relay, goes to pin 6 output ?  Whats #6 for ?

Right now I have a light switch to turn power on PS w/ an inline fuse.  Is the SW-06 IEC Switch some type of safety feature ?

Sorry for all the ques, but Ive gotten this far w/out burning anything up. ;D

 In your opinion what would be the best route to cutting power to the steppers ?

The 48v PS.  or the drives ?  I have some different electronic relays to incorporate, if needed.

Leaving the A/C motor out.  My E-Stop switch is mechanically hooked to the mill off switch.

The E-Stop switch I have has modules to swapped out. NO and NC.

Jeff, that made it more clear for me.

In other words, I can only use 1 port for Mach3 estop input, to shut down the Z driver and Gecko 540 .

Maybe tie in the EN+ from the Z driver ?  For me, its a guess for now. Here is the setup for the Z BOB- http://wiki.zentoolworks.com/index.php/Zen_Toolworks_Stepper_Motor_Driver_Breakout_Board(5_Axis_Output_with_on_board_spindle_relay)

Gecko 540 for X-Y-A, Port 1,  Pin 10, NC side of Stop Switch

ZTW 5 axis BOB for Z,  Port 2,  Pin 10, NO side of Stop Switch

Is there a way to setup Mach3 w/ 2 ports for the Estop  ?

I have 2 ports . Input Signals Config only has 1 Estop setup.

Mach3.
