Load gear position tracking
Terminology
● Encoder range
● Singleturn encoder
● Multiturn encoder
Description
Position tracking enables reproduction of the position of the load when gears are used. It can
also be used to extend the position area.
With position tracking, a load gear can also be monitored if the "position control" function
module is active (p0108.3 = 1).

value r0483 comprises the following position information:
● Encoder pulses per revolution (p0408)
● Fine resolution per revolution (p0419)
● Number of resolvable revolutions of the rotary absolute encoder (p0421), this value is
When position tracking is activated (p2720.0 = 1), the encoder position actual value r0483
comprises the following:
● Encoder pulses per revolution (p0408)
● Fine resolution per revolution (p0419)
● The gear ratio (p0433/p0432)

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 inside an encoder rotation.
A multiturn encoder is an absolute encoder that provides an absolute image of several
encoder revolutions (e.g. 4096 revolutions).
