Festo P.BE-CMMD-AS-HW-EN 1002NH  

Among other issues, the EN 60204-1 standard deals with the handling of emergencies and 
defines the terms EMERGENCY OFF and EMERGENCY STOP (see table). 

 

Handling 

Definition (EN 60204-1) 

Danger case 

EMERGENCY 
OFF 

Electrical safety in case of emergency by 
switching off the electrical energy to all or 
part of the installation. 

EMERGENCY OFF is to be used where a risk 
of electric shock or other electrical risk 
exists. 

EMERGENCY-
STOP 

Functional safety in an emergency by 
bringing a machine or movable parts to 
a standstill.  

EMERGENCY STOP is used to stop a process 
or a motion if this creates a danger. 

Table 4.1 EMERGENCY OFF and EMERGENCY STOP as per EN 60204-1 

 

The standard EN 61800-5-2 describes various safety functions that can be used 
dependent on the application.  
For the position controllers of the CMMD-AS family, the STO and SS1 safety functions 
have been implemented through external circuitry. 
Galvanic isolation does not occur with the STO function. As a result, this does not have 
any protective function against electric shock. In the sense of the standards, an 
EMERGENCY-OFF system cannot be implemented with the STO, because this requires the 
complete system to be switched off via a mains power isolator of some kind (main power 
switch or mains circuit breaker).
