signals parallel interface
1 - 24
D0 - D23
Data lines D0 to D23.
24 parallel output signals. For each data line,
we recommend pull-down resistors for PNP
and pull-up resistors for NPN, both with
4.7 kOhms. D19 - D23 for low resolutions
these outputs can be assigned for special
outputs.
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 interference 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 potential (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 absolute 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.
F/R counting direction input. When not
connected, this input is on HIGH. F/R-HIGH
means increasing output data with a clock-
wise hollow shaft rotating direction when
looking at the flange.
F/R-LOW means increasing values with
a counter-clockwise hollow shaft rotating
direction when looking at the flange.

preconditions for programming
- PC with RS 232 interface and Windows operating system
- programming software ProGeber, manual
- programming cable connection, connecting the absolute
encoder with the PC
If necessary order separately under accessories.
description of diagnosis and special functions
When turned on, the encoder will carry out a self-testing.
The following is monitored during operation:
- check of the code steadiness
- whether admissible signal frequency is exceeded
- LED failure, aging
- whether receiver has failed
- code disc, broken glass
- supply voltage of electronically controlled gearbox
Special functions:
- two preselections „limit switch function“
- speed monitoring can be programmed
- status of diagnosis and mode
