9.3.26.1 General information
Terminology
● Encoder range
The encoder range is the position area that can itself represent the absolute encoder.
● Singleturn encoder
A singleturn encoder is a rotating absolute encoder, which provides an absolute image of
the position within one encoder revolution.
● Multiturn encoder
A multiturn encoder is an absolute encoder that provides an absolute image of the
position over several encoder revolutions (e.g. 4096 revolutions).
Description
Position tracking enables the load position to be reproduced when using gears. 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 Chapter "Actual position value preparation (Page 635)".
