Sigma II User’s Manual Chapter 5: Parameter Settings and Functions5 - 225.2.3 Using the Encoder Signal OutputEncoder output signals divided inside the servo amplifier can be output externally.These signals can be used to form a position control loop in the host controller.The output circuit is for line-driver output. Connect each signal line according to thefollowing circuit diagram.Note: Dividing means converting an input pulse train from the encoder mounted on the servomotoraccording to the preset pulse density and outputting the converted pulse. The units are pulses perrevolution (PPR).PGServo amplifierCN2 CN1(Servomotor)EncoderHost controllerPhase APhase BPhase CSerial data/PBOR = 220 to 470ΩC = 0.1μF (Decoupling capacitor)PBOPPP represents twisted pair wires.P/PCOPCO/PAOPAOPhase APhase BPhase CCN1-33CN1-34CN1-35CN1-36CN1-19CN1-20CN1-1Phase APhase BPhase C0VChoke coilSmoothingcapacitor160V +5V89107C+-+5V110V6 5321RRRServo amplifier Host controllerLine receiverShieldConnector shell
