Description
The ENA42HD series are high precision encoders
with internal magnetic sampling.
This multiturn absolute encoder transmits a position
value corresponding to the shaft setting via its
interface.
The control module sends a start sequence to the
absolute encoder to obtain the position data. The
rotary encoder then sends the position data
synchronous to the cycles of the control module. It
is possible to select the counting direction with the
function input.
