The encoder frequency-division output circuit outputs OC signals via the differential drive. Generally, it
provides feedback signals to the host controller in the closed-loop position control system. A differential or
optocoupler circuit shall be used in the host controller to receive feedback signals. The maximum output
current is 20 mA.
2.3.3 Communication Signal Terminal Connectors CN3/CN4
The CN3/CN4 terminals of the servo drive are used for communication connection between the servo drive
and the PC, PLC, and other servo drives. The following table describes the pin denitions of the CN3/CN4
terminals.
