1.5 General functional description

1.5.1 Absolute Encoder

In contrast to incremental measuring systems, the absolute measuring system
provides the current position value instantaneously. If this measuring system is moved
mechanically in the deactivated state, the current position can be read out directly as
soon as the voltage supply is switched on again.
The TR absolute measuring systems can be supplied in Single-Turn or Multi-Turn
versions depending on the type required.
Single-Turn
This measuring system resolves a single revolution or turn of the drive shaft into
measuring increments (e.g. 8192). The number of measuring increments per
revolution is recorded and balanced via a code disk. This measured value is output via
different interface modules depending on the type of interface used, and is repeated
after each revolution.
Multi-Turn
Besides the angular positions per revolution, multi-turn measuring systems also record
multiple rotations or turns. The drive shaft is connected to an internal reduction gear
via which the number of revolutions is recorded.
In the case of the multi-turn measuring system, the measured value is thus composed
of the angular position and the Number of Revolutions. The measured value is also
balanced and output via different interface modules depending on the type of interface
used.
