2.2.5
Activation and deactivation of protection zones
General
The activation status of a protection zone is:
•
Preactivated
•
Preactivated with conditional stop
•
Enabled
•
Deactivated
A protection zone is monitored for violation only when it is activated.
Activation
The activation of a protection zone can take place through:
•
Part program instruction
•
Automatically after the control powers up
•
PLC user program
For activation through the PLC user program, the protection zone must be first
preactivated via a part program.
The preactivation, deactivation and activation of all protection zones always takes place
channel-specifically. A protection zone can also be active in multiple channels
simultaneously (application example: Double-slide single-spindle machine with one quill and
two machining slides.
Protection zones are activated immediately after the runup of the control, if the
corresponding system variable $SN_PA_ACTIV_IMMED[n] or. $SC_PA_ACTIV_IMMED[n]
has been set.
Note
Machine-related protection zones are activated after the runup of the control in all channels.
An activated protection zone is only taken into account after the successful referencing of all
participating geometry axes.
