16 cam outputs
Up to 250 cams can be programmed to
these 16 outputs. For each data line, we
recommend Pull-DOWN resistors for PNP and
Pull-UP resistors for NPN, both with 4.7 kΩ
values.

not used
20 - 24
factory diagnostic outputs
D19 - D23
These outputs may be assigned, at choice,
to the functions preset 1, preset 2,
speed monitoring or diagnosis.
27 ZERO
Reset input for setting a zero at any point
within the programmed encoder resolu-
tion. The zero setting is triggered by a HIGH
pulse imperatively after the sense of direction
has been chosen (F/R). Assign to GND for
maximum interference immunity after
zero setting. Pulse duration
≥
100 ms.
28 ENABLE
If this input is at LOW level, the output
drivers will be activated. If HIGH potential is
applied (or if open-circuited), the output
drivers will turn to the HIGH-resistance
state (Tristate).
29 STORE
When a LOW level is applied, the data of
the absolute encoder is temporarily stored.
If this input is connected to HIGH potential
or if it remain closed, the current position
data of the absolute encoder is switched
through to the output drivers. This line
must be used to ensure data readout in
binary code.
30 F/R
Input for counting up and down. If open-
circuited, it is set to HIGH. HIGH means
increasing output data if shaft rotates clock-
wise when looking at the flange. LOW means
increasing values if shaft rotates counter-
clockwise when looking at the flange.
34 GND-Sense This contact is connected internally to GND
and assists, together with VS-sense, to
measure the supply voltage at the encoder via
the follower electronic.
35 +V
S
-Sense This contact is connected internally to +Vs.
If the sensor line is not to be used, this contact
must be isolated (danger of short circuit).
36 +Vs
Supply voltage of encoder.
37 GND
Ground contact of encoder with reference
to +Vs.
