The SP function transfers the safely determined actual position values in the drive to a safety controller via safe PROFIsafe communication.
Unlike the SLP function, which monitors the current actual position value against a limit within the drive and initiates an autonomous fault response by the drive to an overshoot, SP communicates the current actual position values to the safety control. Monitoring functions can be implemented in a flexible manner in this case.
Tailored safety concepts can be developed with the SP function. The function is particularly suitable for machines where flexible safety functions are required. It can be used in a wide range of applications, e.g. to implement safe, axis-specific range recognition via safe cams (SCA). The SP function can also be used to design cross-axis safety concepts, multi dimensional protection areas and zone concepts.
Additional sensors or external safe encoders, their installation and evaluation are not necessary to monitor protection areas. The SP function goes beyond the safety functions stated in IEC 61800-5-2.
