2 Introduction
Drive-based safety with L-force | 9400
The controllers of the L-force | 9400 range can be equipped with a safety module. The functional
range of the safety module types varies in order to optimally implement different applications.
"Integrated safety technology" stands for user-related safety functions that are applicable to the
protection of persons working with machines and the machine protection.
The motion functions are still executed by the controller. The safety module monitors the safe
compliance with the limit values and provides the safe inputs and outputs. When the limit values
are exceeded, the safety module starts the control functions in accordance with EN 60204-1 directly
in the controller.
The safety functions are suitable for applications in accordance with IEC 61508 up to SIL 3 and meet,
depending on the module, the requirements of EN ISO 13849-1 up to control category 4 and
Performance Level (PL) "e".
