Assuming the controller has been configured correctly and the machine does not have mechanical issues that allow the feeder to slip on the material, none of these changes will matter because the conditions they are testing for will not happen.

Prior to this change, the Feed Angle input was tested after the move to ensure that the feed did not arrive late to the target. Depending on the configuration of the controller and the type of move, losing the Feed Angle input during the move is sometimes expected. Those conditions will not be covered here. The rest of this SCN concerns itself with the cases where the Feed Angle input is expected to be present during the entire move.

We have a customer that has requested that we monitor the Feed Angle input through out the entire move and stop both the Press and the Move if the Feed Angle input is lost.

Their Press Controller, and apparently others, have a Press Stop input. This input tells the press to stop imediately as somehow simply turning off our Press output allows the press to continue through the current press cycle.

On Continous Press controllers output 3 is now the Press Stopped output. We monitor the Feed Angle input during the entire move. If the Feed Angle input turns OFF unexpectedly we will turn ON the Press Stopped output, turn OFF the Press output and display the Press Miss-Feed error. The Press Stopped output remains ON until the user acknowledges the error by clearing it. Entering the Run mode is also prevented until the error is acknowledged.

This change increases the likelihood that the Feed Angle input may not be ON when attempting to enter the run mode. A test for the Feed Angle input was added as a permissive for entering the run mode. If the Feed Angle input is OFF an error is displayed indicating that the Feed Angle input must be ON.
