We are using Euromap 67 on an Arburg IMM. We want to make the IMM stop the operator from crushing the robot arm in between the open mold when he or she manually “close mold”. Would we be using Mold Area Free light curtain?, if so, how to implement that in Polyscope?
Hello,
Yes you would use the Mold Area Free electrical signal that is on the IMMI board. In Polyscope, there are no software settings to configure. The MAF signal is jumped by default from the factory, however you can remove that jumper (pictured below) and wire in your own 24V light curtain signal. When no 24V signal is sent to MAF, even if you permit mold close from the robot’s teach pendant, it will not send the permission to the IMM.
The MAF signal is not intended as a safety signal, rather it is a redundancy to prevent accidental machinery damage by not allowing the mold to close on the robot. You can read more detail here: Product Alert: Safety Notice for All UR IMMI and Euromap products
