Depending on the model of the RC7 controller (standard or global), the e-stops channels are hard wired via the Mini I/O (CN5) connector or the Safety I/O (CN10) connector. I do not believe you can disable them.
I'd also be interested in a solution to this, as I might have a similar problem.
A while ago I salvaged a Denso VP-5243 robot together with an RC7M controller (it was connected to an instrument I worked with, so I'm not an expert when it comes to robotics; both instrument and robot were thrown out). I just tried to get the whole thing to run, but I end up with a '2008 Level1' error code (e-stop engaged). I enabled the switch on the pendant, but the robot had a fence with some reed switches - which are now missing. But I don't remember anything being plugged into the CN5 or CN10 inputs (it's been a while, though).
But would it be possible to plug a dummy connector into the CN5 or CN10 ports with some relevant pins bridged (?), which would then simulate the e-stop being present?
