The D-Sub 15 pins high-density connector is only available on the DSCDP3xx-xxx.
Remark:
The +5VDC encoder supply output is protected by the fuse F3 (1A) on JC5 and JC6.
Refer to the corresponding ’Operation & Software Manual’ for more information about the use
of the EHO and ELS signals.
JC5 is used to connect the encoder of motor 1 and JC6 for the one of motor 2.
3.1.1.2 Absolute analog encoder (EnDat 2.1)
The EnDat 2.1 is an absolute encoder. It has 1Vptp signals with a load resistor R
0
=120Ω. Its signals are
similar to the incremental encoders (without the index), but it additionally includes a RS485 serial link (EIA
standard, EnDat 2.1 interface) for the absolute position measure: EDT (serial data) and ECL (clock). The ECL
(clock) signal is received from the DSCDP. From its first falling edge (latch signal), the absolute position will
be defined within one incremental signal period (depends on the encoder type).
The D-Sub 15 pins high-density connector is only available on the DSCDP3xx-xxx.
