Machine Data and Cam Data
Address Name
24.0 DISP_REV
With the machine data "distance per encoder revolution" you inform the FM 452 of the distance
covered by the drive system per encoder revolution.
The value "distance per encoder revolution" depends on how the axis is set up and how the encoder is
installed. You must take into account all transmission components such as couplings or gearing.
Section 8.6 (Page 8-20) describes the relationship between the machine data "distance per Encoder
Revolution" and "increments per encoder revolution".
