5.2 Setting Common Basic Functions5-55 Operation5.2.2 Servomotor Movement DirectionThe servomotor movement direction can be reversed with parameter Pn000.This causes the travel direction (+, -) of the shaft reverse, but the encoder pulse output and analog monitor sig-nal polarity do not change.Before performing this operation. Motor Phase (Pn080.1) must be set correctly. For the setting method, refertoΣ-V series User’s Manual, Setup, Linear Motor (SIEPS80000044).By selecting the movement direction with this parameter, the polarity of the reference can be adjusted to themovement direction without changing the polarity of reference pulses and reference voltage to the SERVO-PACK.Note 1. The count of linear scale can be checked with Feedback Pulse Counter (Un00D).2. According to the change of motor movement direction, the direction of overtravel forward/reverse is alsoswitched.For Pn000 = n.0: The linear scale counting up direction is forward movement (P-OT).For Pn000 = n.1: The linear scale counting down direction is forward movement (P-OT).Parameter MeaningPn000n.0Standard setting(Forward movement is thelinear scale counting updirection.)(Factory setting) Forward Reference Reverse Referencen.1Reverse movement Mode(Forward movement is thelinear scale counting downdirection.)
