„ Output Circuit Interfaces
Any of the following three types of servo amplifier output circuits can be
used. Connect an input circuit at the host controller following one of these
types.
• Connecting a line-driver output circuit
Encoder serial data converted to two-phase (A and B phase) pulse
output signals (PAO, /PAO, PBO, /PBO), origin pulse signals (PCO,
/PCO) and S phase rotation signals (PSO, /PSO) are output via line-
driver output circuits that normally comprise the position control
system at the host controller. Connect the line-driver output circuit
through a line receiver circuit at the host controller.

See 3.5 Wiring Encoders for connection circuit examples.
• Connecting an open-collector output circuit
Alarm code signals are output from open-collector transistor output
circuits. (AL01 – CN1-37, AL02 – CN1-38, AL03 – CN1-39)
Connect an open-collector output circuit through an optocoupler, relay,
or line receiver circuit.
