Fanuc R30iA - Interference Option

[Steph M]

Good day everyone.

I have an issue with the Fanuc R30iA interference option.
My issues is as follows:
When the robot is not in the interference zone the associated output is turned on, as the robot moves into the zone the contact becomes disabled or turns off. While the robot remains in the interference area the controller power is cycled. After power is restored, the interference contact/output is turned on, thus indicating that the robot is no longer in the interference area, even though it remains in the zone.

It seems to me that the result after a power cycle should be, the contact reflects the robot current position.

Has anyone else experienced this?Or experience with this?
