SLP (Safely Limited Position)
Target position monitoring
Amount:
cf. The chapter
“Safety functions”
Input:
standardised position signal X from encoder interface
RESET function:
The violation of the permitted monitoring range and requires a RESET
confirmation. The RESET confirmation is alternatively carried out via:
▪
RESET function in the group Input elements.
▪
Function button at the front side of a basis group
▪
Fieldbus Reset Input
Description of the function:
•
Calculation of the current velocity V from the position signal X
•
Determination of the stop distancein relation to the current statuses of acceleration and
velocity
=> Cyclical determination of the Stop_Distanz
Akt.
= f (V, a) with a = acceleration

•
Direction-dependent enabling of the function CW = count-up CCW = count-down
NOTICE:
If the function is enabled, it must be programmatiocally and automatically ensured
that CW and CCW never are
“1” at the same time because otherwise an alarm is
triggered.
