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 denitions of the CN3/CN4
terminals.
