OUT-/DIR- can connect to a 470
Ω
pulse input interface COM via
J2/J3. Choose OUT-/DIR- to connect to OUT/DIR.

Encoder Feedback Signals EA, EB and EZ
The encoder feedback signals include EA, EB, and EZ. Every axis
has six pins for three differential pairs of phase-A (EA), phase-B
(EB), and index (EZ) inputs. EA and EB are used for position
counting, and EZ is used for zero position indexing. Its relative sig-
nal names, pin numbers, and axis numbers are as follows.
NOTE:
NOTE:
If the pulse output is set to open collector output mode, OUT-
and DIR- transmit OUT and DIR signals, with sink current not
exceeding 20mA on the OUT- and DIR- pins, and default set-
ting 1-2 shorted
CAUTION:
Sink current exceeding 20mA will damage the 26LS31.
