I have a system that requires the servo amplifier of the robot be dropped out(locked) when entering the workcell. Anyone know how to do this properly on this new controller?

Your workcell should have a safetyfence or lightscreen, connect that to the FENCE or emergency connections and it will do the job.

I have the same type of customers. Fanuc initially was not going to support doing this, I understand that now they are. I do not have any details yet to share. Kluk Kluk, there are plants that require the servo power to be physically dropped by a servo disconnect switch seperate from any fence/safety circuits.

FYI..... per FANUC, "......as present the R-30iB does not offer a Local/Remote Servo Disconnect Option. If Servo Disconnect is required, we offer this option on the M-410iB/160 R-30iA unit. Therefore, if required, my solution today would be the Remote Servo Disconnect, P/N: R-30iA ME-R30iA-470. It comes with a 7, 14 or 21 meter cable selection allowing mounting of the Remote Disconnect at the edge of the cell. "

Is that controled by hand or automatic ?

In my case, it's a disconnect the operator would throw and lock out before entering the cell.

Why not simply use a e-stop button that you can lock? Robot in e-stop can't do nothing.

You have a good point. But I as an integrator have to satisfy my customer's requirements.

What robot are you using or is this a blanket question of what to do in general for this controller? In the R30ia (and older) we always connected a 3phase disco switch between the breaker and the CRM2 contactor. We also put aux contacts on the switch that connect to the SD inputs on the interface board. I have yet to look at the controller. We have a new 710 setting on our shop floor. I can get more info soon. I know fanus 'says' they dont support it, be we were told they are going to. I just have to find out more info.

Blanket question for this controller.

Why can't you connect to the servo on/off inputs in the controller?

You have a good point. But I as an integrator have to satisfy my customer's requirements.Note, these are not accepted as requests...but requirements. I have the same type of customer with the same demands. The servo 'SD' connections are used and are connected to a set of aux contacts on the disconnect throw switch box. They break and initiate an E-stop. They also prevent a SRVO-DCLV error because the servo power has disappeared. I still do not have a good answer yet on this. I have an M710-50 on the r30ib controller that will have a servo disconnect attached to it in 2 weeks. I was told that fanuc was supplying this or at least approving this. I need to see what the plant has nogotiated because Im still in the dark a little here.
