Safely-limited increment (SLI)

Brief description
In the case of the safety function Safely-limited increment, dual-channel moni-
toring prevents the drive from moving by more than one maximum increment
[P‑0‑3290.x.3 (x=1..16)]. Within the position window (maximum increment) it is
possible to move in both directions.
To define a new position window it is necessary to exit the safety function
"Safely-limited increment" and select it again. This can be done by changing to
a different motion mode (SMM1 - SMM16) or by temporarily deselecting the
active motion mode.

Safety functions in special mode "Safe motion SMMx"
The safety function is active if it is parameterized for the special operation
upon selection "Safe motion SMMx" (P‑0‑3290.x.1 with "x"=1-16 for SMM1-
SMM16).
The safety functions are selected via the active "SafeMotion" profile
(P‑0‑3264).
For example, the 16 different Safe motions (SMM) with the corresponding
directions can be selected via the SMMx signals 1 to 16 (A_SMMx, x=1..16)

Switching to the monitoring of the direction of motion. When the drive
moves in the non-enabled direction of motion, the traveled distance has to
be smaller than P‑0‑3270.x.3.
