The following safe monitoring functions are available:
} Speed
} Speed range
The safety functions of the PNOZ m EF 2MM are monitoring functions, whereby a safe out­
put signal is used to show if defined limit values are exceeded.
The reaction function that takes place (e.g. shutting down the drive, activating a mechanical
brake) when exceeded limit values are detected during the normal operation of the safety
function must be defined and implemented by the machine/plant developer and does not
form part of the PNOZ m EF 2MM.
The monitoring function of the PNOZ m EF 2MM can be used to implement safety functions
defined in the standard EN 61800­5­2 for Adjustable speed electrical power drive systems.
