Product Overview
1-2 FM 452 Electronic Cam Controller
C79000-G7076-C452-04
1.1 What is the FM 452?
The FM 452 function module is a single-channel, electronic cam controller and is
used in the S7-400 programmable controller. It supports both rotary and linear
axes. When used for position sensing, you can connect initiators, incremental, or
absolute encoders (SSI). As a slave, the FM 452 can listen in on the SSI frame of
an absolute encoder.
You can use up to a maximum of 128 distance or time cams that you can assign to
32 cam tracks as required. The first 16 cam tracks are output via the digital outputs
on the module. For information about the functions and settings of the cam
controller, please refer to the following chapters.
You can operate several FM 452 modules at the same time. Combinations with
other FM/CP modules are also possible. One typical combination is to use the
module in conjunction with an FM 451 positioning module.
