7.5 Encoder Divided Pulse Output7.5.1 Encoder Divided Pulse Output Signals7-217 Application FunctionsNote: The count direction (up or down) of the linear encoder determines whether a phase-C pulse is output. Theoutput of the pulse does not depend on the setting of the movement direction (Pn000 = n.1). When First Passing the Origin Signal in the Forward Direction and Returning afterTurning ON the Power SupplyThe encoder’s phase-C pulse (CN1-21 and CN1-22) is output when the origin detection posi-tion is passed for the first time in the forward direction after the power supply is turned ON.After that, the phase-C pulse is output whenever the origin detection position is passed in theforward or reverse direction. When First Passing the Origin Signal in the Reverse Direction and Returning afterTurning ON the Power SupplyThe encoder's phase-C pulse (CN1-19 and CN1-20) is not output when the origin detectionposition is passed for the first time in the reverse direction after the power supply is turned ON.However, after the origin detection position is passed in the forward direction and the encoder’sphase-C pulse is output, it will then also be output when the origin detection point is passed inthe reverse direction.Encoder Model Interpolator Linear Encoder Pitch [μm]SL710 PL101-RYMJ620-T13800SL720 800SL730 800SR75 80SR85 80SQ10 MQ10-FLA 400MQ10-GLAEncoder count-updirectionOrigin detectionpositionPower ONpositionPhase-C pulseoutputTimeThe SERVOPACK records the position wherethe phase-C pulse was output for movementin the forward direction, and the phase-Cpulse is also output for reverse movement.Encoder count-updirectionOrigin detectionpositionPhase-C pulseoutputPower ONpositionThe phase-C pulse is notoutput when the detectionposition is passed in thereverse direction.TimeThe SERVOPACK records the position wherethe phase-C pulse was output for movementin the forward direction, and the phase-Cpulse is then output for reverse movement.
