Estop w/ 2 Ports
« on: January 02, 2015, 10:16:08 PM »
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.

It will all depend on the breakout boards you are using, some can easily be linked together so that the E-Stop will disable both breakout boards.

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

Mach, like all other controllers I know of, only has one input for E-Stop. It will be up to you to tie your E-Stop in to your hardware.
For example most industrial machines have an E-Stop string that takes in things such as limits and fault signals from drives etc. Any one of these will not only tell the controller (Mach in this case) but also there will be hardware stops, things such as contactors dropping out the power to the drives or safety relays sending Stop signals to drives etc etc.
 If your breakout can do similar, ie disable all I/O on an E-Stop signal then you may be able to tie things in that way

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)

The Mach3 'EStop' input is just to tell Mach3mand EStop occurred. An EStop must function independently of the PC or any circuit board in your machine. On a small machine this can be done by having a suitable EStop in series with a power supply mains feed. On a larger machine you need to use a safety relay/contactor.

 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.

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
