Safety engineering Basics Introduction Safety engineering Basics 1.1.1 Introduction With increasing automation, protection of persons against hazardous movements is becoming more important. Functional safety describes the measures needed by means of electrical or electronic equipment to reduce or remove danger caused by failures. During normal operation, safety equipment prevents people accessing hazardous areas.
Terms and abbreviations of the safety engineering 1.1.3 Terms and abbreviations of the safety engineering Abbreviation Meaning 9400 Lenze servo controller Cat. Category according to ISO 13849−1 (formerly EN 954−1) OSSD Output Signal Switching Device, tested signal output PROFIsafe Pulse width modulation SD−In...

Safety engineering Basics Safety instructions Danger! If the request for the safety function is cancelled, the drive will restart automatically. You must provide external measures which ensure that the drive only restarts after a confirmation (EN 60204). Danger! When the "safe torque off" (STO) function is used, an "emergency switching−off"...
Safety engineering Basics Hazard and risk analysis 1.1.6 Hazard and risk analysis This documentation can only accentuate the need for a hazard analysis. The user of drive−based safety must concentrate on dealing with the standards and legal position: Before putting a machine into circulation, the manufacturer of the machinemust carry out a hazard analysis according to the Machinery Directive2006/42/EC (until 28 December 2009: 98/37/EC) to find out the hazards related to the application of the machine.

Safety engineering Basics Overview of sensors Active sensors Active sensors are units with two−channel semiconductor outputs (OSSD outputs). Drive−based safety integrated in this device series allows for test pulses < 1 ms to monitor the outputs and cables. P/N−switching sensors switch the positive and negative cable or signal and earth cable of a sensor signal.
Safety engineering Device modules Slot Device modules 1.2.1 Slot The slot for the safety modules is marked in the documentation with M4. It is the lowest slot in the controller (see overview in the documentation of the controller). 1.2.1.1 Mounting E94AYAX001 1.2.1.2 Dismounting...
Safety engineering Device modules Function mode of the safety modules 1.2.2 Function mode of the safety modules C00214 The code C00214 must comply with the plug−in safety module type so that the controller is able to operate. Disconnecting paths The transmission of the pulse width modulation is safely (dis−)connected by the safety module.
Safety engineering Device modules Safety module SM0 1.2.3 Safety module SM0 1.2.3.1 Overview The type designation of the module is E94AYAA. Function There are no safety functions available. ƒ This module is required to operate the controller without safetyfunctions. ƒ Note! If safety functions are required, replace the SM0 module by a module with safety functions (e.g.
Safety engineering Device modules Safety module SM100 1.2.4 Safety module SM100 1.2.4.1 Overview The type designation of the safety module is E94AYAB. Function Safe torque off ƒ (up to now: Safe standstill, protection against unexpected start−up) Danger! If the request for the safety function is cancelled, the drive will restart automatically.
