Interfaces
Incremental signals » 11 µA
PP
HEIDENHAIN encoders with » 11 µA
PP
interface provide current signals. They are
intended for connection to ND position dis-
play units or EXE pulse-shaping electronics
from HEIDENHAIN.
The sinusoidal incremental signals I
1
and
I
2
are phase-shifted by 90° elec. and have
signal levels of typically 11 µA
PP
. The
illustrated sequence of output signals—I
2
lagging I
1
—applies for the retracting
plunger.
The reference mark signal I
0
has an un-
ambiguous assignment to the incremental
signals.
Signal period
360° elec.
