Has any done, or know if a control pendant can be wired onto a G0800? Thanks.

I too have studied the diagrams for the Delta drive and the Grizzly. I recommend that you should not interfere with the panel mounted e-stop/ reset circuit due to the fact that it uses some "multi-step inputs MI3 & MI4" which require factory setting parameters and the speed setting should not be necessary in the remote pendant. The start and stop function could be accomplished with 2 momentary contact buttons and a contact output, which would require making a change to the to a parameter and require a 4 wire cord. The simplest would be a form of E-stop button that locks in the depressed position (removing the run signal) and would start by a twist to unlock. The local / remote selector for either method would be located in the pendant. The 2 button would be the safest because when switching to remote you would still have to push the stop button whereas if the twist lock button was left in the run position the drive would start as soon as remote was selected. In the diagram below the items in the box are everything needed in the pendant.View attachment 33196
All VFD's have accel and Decel ( decel is the electronic brake and if you really want to stop fast a braking resistor can be installed to absorb the excess energy). The drive should be stopped properly so that it is not holding at zero speed and that brings up another parameter minimum speed, that all VFD's have. The way that the G0800 is wired is not a true E-Stop because it does not interrupt the power source, instead it just tells the drive to stop so pulling the plug at the days end is probably the smart thing to do.Chris - I almost always use just the speed dial for starting and stopping the lathe. I don't like starting the lathe with the speed dial already turned up. In addition, I read somewhere that using the forward/reverse/off switch for start and stops does not allow for the electronic brake to get properly set. I really don't know if that's accurate information or not. I'm also in the habit of hitting the e-stop button when I'm done for the day, waiting a few minutes, and then unplugging it.
