assignment
signals for parallel input interface
1 - 24
24 parallel output signals.
Data lines D0 to D23. With PNP, pull down;
with NPN, 4.7 kΩ pull up resistors recom-
mended for each data line.
Zero setting input for setting a zero at any point
within the programmed encoder resolution.
The zero setting process is triggered by a HIGH
pulse and should take place after direction of
rotation selection (F/R). For maximum interfer-
ence immunity after zero setting, connect to
GND. Pulse duration
≥
100 ms.
If this input is at LOW level, the output drivers
will be activated. On application of HIGH po-
tential (or unconnected), the output drivers
assume a HIGH-resistance state.
By applying a LOW level, the data of the
absolute encoder will be buffered. If this input
is connected to HIGH potential or remains
open, the current position data of the abso-
lute encoder will be switched through to the
output drivers. For reliable readout of the
data, this line must be used in the case of
Binary-Code.
By applying a HIGH potential, ascending val-
ues will be output when the shaft rotates cw
(looking at shaft). If LOW potential is applied,
descending values will be output.
