7.22 Position tracking

Position tracking

● Encoder range

The position area that can itself represent the absolute encoder.

● Singleturn encoder

A rotating absolute encoder, which provides an absolute image of the position within one

encoder revolution.

● Multiturn encoder

An absolute encoder that provides an absolute image of the position over several

encoder revolutions (e.g. 4096 revolutions).

Position tracking enables the load position to be reproduced when using gearboxes. It can

also be used to extend the position area.

With position tracking, an additional measuring gear can be monitored and also a load gear,

if the "position control" function module (p0108.3 = 1) is active. Position tracking of the load

gearbox is described in Section "Actual position value processing".
