Control via PROFIsafe
● Implement a user program in your F-CPU with the following steps to implement a retract
function:
– Select SDI positive in the case that the lower SLP limit is violated, or SDI negative if the
upper SLP limit is violated
– Wait until the selected SDI is active, then deselect SLP
– Safe acknowledgment of the limit violation
– Movement of the drive with suitable setpoint inputs in the range that has been enabled
– Select SLP
– Wait until SLP is active, then deselect SDI
