Activate channelspecific protection zone 1 ( ...10)
Signal state 0 or
The pre-activated, channelspecific protection zone 1 ( ...10) is de-activated by the PLC user
edge change
program.
1 → 0
The protection zone is immediately de-activated.
Only protection zones that have been activated via the PLC and have been pre-activated in the NC
part program can be de-activated.
Application
Before a synchronous spindle, for example, is moved into the working range, the relevant
example(s)
machinerelated protection zone can be activated.
