I need to control the clamp and unclamp of the lathe on an LB3000 using Thinc API. I've gone through the documentation and it looks like I can set a lot of chuck specific variables, but I don't see anything for clamping/unclamping the chuck itself. Thanks.
There are several things which effect the safety of the machine that cannot be controlled via the standard API, chuck clamp / unclamp being one of them.
The only way to control the chuck via API is by using the IO Variables Option Part # :8303 and hard-wiring the appropriate signals yourself.
Alternatively, Robot Interface Type D (5A5-8269-10) will allow access to those signals and more via a network interface, the Anybus X-gateway. An application could connect to this gateway and control the desired signals that way.
