Hello, I have an Estop on my control box for my mill that is switching 5volts. Well now I want the same Estop switch to shutoff my WJ200-022SF VFD on GS1 and GS2. The problem is 24VDC is on GS1 and GS2. So what type of Estop switch is out there so that I can put 5 volts and 24 volts through the same switch to shut the VFD down and Mach3 at the same time? The situation I have is, I have an engraving spindle I am putting on my mill that will be run by the WJ200 VFD and will not be controlled with Mach3. So when Mach3 is moving X,Y,Z axis I want to be able to hit the Estop button and shut both the VFD and Mach3 down at the same time.

Any suggestions would be helpful,

Thanks,

Jeff

Use a relay to switch it, controlled by the Estop. You can also get Estop switches where you can put two NC switches, one for 5V and one for 24V.

You can use a double poll or three/four relay to accomplish what you want. You will need to get either a 5V relay or 24V relay and the output of the supplies will be routed through the Normal Open contacts, when the Estop is hit the relay will open killing both 5V and 24V to their circuits except the power that feeds the relay itself.
