Safely-Limited Position (SLP)

Definition according to EN 61800-5-2:
"The SLP function prevents the motor shaft
from exceeding the specified position limit(s)."
The Safely-Limited Position function (SLP) is used to safely monitor the limits of two

Examples of how the function can be used
Example
The drive must not exit the specified position rang-
es.
Features
● Selection via terminals or PROFIsafe
● 2 position ranges, each defined by a limit switch pair

● Settable stop response
● To run the motor out of the prohibited range, you must perform a special sequence (see
Chapter "Retraction (Page 182)").
