10.10 Safely Limited Position (SLP)
NOTE!
The safety function SLP is supported by the Safety Module SAF-003.
The safety function „Safely Limited Position (SLP)“ assures, that the parameterized
absolute position limits are not exceeded by the principal drive mode. After activating the
function the compliance with the parameterized position limits are monitored.
The drive’s maximum limited moving range is defined with the parameters „Position limit
1“ and „Position limit 2“.

During noncompliance with "SLP" after a parameterizable "SS1" time "STO" is initiated
The Safety Module must know the safe absolute position in order to execute the safety
function SLP. Upon first request of the safety function homing must be executed. The
Safety Module requests an execution of homing at the controller via the communication
interface (SPI) .
The reaching of the homing position via a control cable is signaled from the Safety Module
to the controller.
The sensing of the homing position is made e.g. via a position switch, which occupies a
safe Safety Module input on two channels. Additionally, an enabling interface input to the
controller can be parameterized and processed.
