3-24
(2) Line Driver Output Circuit
CN1 connector terminals, 17-18 (phase-A signal), 19-20 (phase-B signal), and 21-22 (phase-Z signal) are explained
below.
These terminals output the following signals via the line-driver output circuits.
•
Output signals for which encoder serial data is converted as two phases pulses (PAO, /PAO, PBO, /PBO)
•
Origin pulse signals (PCO, /PCO)
Connect the line-driver output circuit through a line receiver circuit at the PC or PLC...etc.

(3) Safety Output Circuit
The external device monitor (EDM1) for safety output signals is explained below.
A configuration example for the EDM1 output signal is shown in the following diagram.
Output signal is the source output. It is not able to use the sink output.
