3.2.4 Interface Circuit
This section shows examples of servo drive I/O signal connection to the host controller.
■Interface for input circuit
The input circuit interface connects through a relay or open-collector transistor circuit.Select a low-current relay otherwise
a faulty contact will result.

■Interface for encoder and servo drive output circuits
The amount of two-phase (phase A and phase B) pulse output signals (PAO,/PAO,PBO,/PBO) and zero-point pulse
signals(PCO,/PCO) are output via line-driver output circuits.Normally, the servo drive uses this output circuit in speed
control to comprise the position control system at the host controller. Connect the line-driver output circuit through a line
receiver circuit at the host controller.
■Interface for sequence output circuit
Photo-coupling isolation output is required for output signals of servo alarm, positioning complete and brake interlock.
Note:
Maximum voltage should be no more than 30VDC, and maximum current should be no more than 50mA.
