● Multiturn encoder
Description
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".

The encoder range is the position area that can itself represent the absolute encoder.
A singleturn encoder is a rotating absolute encoder, which provides an absolute image of
the position within one encoder revolution.
A multiturn encoder is an absolute encoder that provides an absolute image of the
position over several encoder revolutions (e.g. 4096 revolutions).
