HLA: Safety Integrated Advanced Functions

The Safety Integrated Advanced Functions require an additional Safety Advanced license.
Advanced Functions with encoder require an encoder with safety capability (see Chapter
"Notes regarding safe actual value sensing using an encoder system (Page 155)").
● Safely Limited Position (SLP)
Safely Limited Position ensures that a freely definable traversing range is not left.
● Transferring safe position values (SP)
The "Transfer safe position values (SP)" function enables you to transfer a safe position
to the higher-level control via PROFIsafe.
● Safe Cam (SCA)
The "Safe Cam" function outputs a safe signal if the drive is within a specified position
range. It facilitates the realization of safe axis-specific range detection.

Safely-Limited Speed ensures that the drive does not exceed a preset speed limit.
Safe Speed Monitor is used for safely identifying when a speed limit is undershot in
both directions of motion, e.g. to identify zero speed. A failsafe output signal is
available for further processing.
Safe Direction is used to safely monitor the direction of motion.
Safely-Limited Acceleration monitors (the same as SLS) the acceleration, and
intervenes when a limit value is violated. SLA cannot prevent that the acceleration
threshold is briefly exceeded.
