Examples of how the function can be used
Example Possible solution
It is not permissible that the drive exits the specified
position ranges.
● Select SLP in the converter; inhibit the range
that is not permitted.
● After the enabled range has been exited, a
parameterizable stop response is initiated.
The Safely-Limited Position function (SLP) is used to safely monitor the limits of two traversing
and/or positioning ranges, which are toggled between using a safe signal.
Features
● Selection via terminals or PROFIsafe
● 2 position ranges, each defined by a limit switch pair
● Safe switchover between the two position ranges
● Adjustable stop response
● To move the motor out of the unauthorized range, you must execute a special sequence
(see "Retraction (Page 164)").
4.13.1 Details and parameterization
The Safely-Limited Position function (SLP) is used to safely monitor the limits of two traversing
or positioning ranges which can be switched over by a safe signal.
Requirements
For the Safely-Limited Position function, the following requirements must be met:
● The use of one or two suitable encoders for the extended safety functions with encoder (see
also Chapter "Safe actual value sensing with encoder system (Page 191)")
● Determining the absolute position of the drive by referencing during commissioning and
after all actions after which a safe absolute reference can no longer be guaranteed (POWER
ON, parking)
