P+F Speed Monitor > Retrofit safety speed monitor new from Pepperl Fuchs


Pepperl Fuchs have produced a speed monitor which permits security functions up

to SIL3/PLe to become retrofitted to existing installations with no security PLCs, relays or possibly a second sensor.

Pepperl Fuchs simplest version features a speed monitor plus a safe 58mm,1,024ppr sin/cos encoder.

The custom chip continuously checks the signals from two encoder tracks offset by 90 degrees although monitoring the provide voltage, temperature and calibration data. It also contains an additional absolute track that provides the precise position from the shaft.


This technique by pepperl fuchs delivers secure quit, speed and acceleration and deceleration ramps which monitor drive shafts by two secure outputs. If the speed is exceeded then the program can initiate emergency stops for instance. The monitor also features a ramp monitoring function which can establish the minimal deceleration path that is definitely needed by referring to speed, position data or deceleration. If the program seems to become losing control then the monitor raises an alarm to prevent a crash. The monitor can be set up applying Pc computer software. A teach- in function can “learn” the present speed by the touch of a button. The exact same configuration may be transferred by using a memory card.
The speed monitor has 4 safe inputs which is usually utilised for connecting normal or security peripherals. The decentralised system can even be upgraded to defend 40 axes using a lot more speed monitor modules. The pepperl fuchs device has a second axis built in which can be linked to other devices by Profibus DP or Profinet.
