Collision avoidance: Protection area active
A protection area is connected with the interface signal via parameter assign‐
ment of the Bit number corresponding with the interface signal, in the system
variables $NP_BIT_NO (Page 228) of the protection area.
Assignment: Bit number ↔ interface signal

Collision avoidance: Stop
Signal(s) updated: Cyclically
The collision avoidance has triggered a stop of the traversing motions in the
channel.
The collision avoidance has not triggered a stop of the traversing motions in the
channel.
Collision avoidance: Velocity reduction
Signal(s) updated: Cyclically
The traversing velocity of the axis is reduced by the collision avoidance.
The traversing velocity of the axis is not reduced by the collision avoidance.
