Origin Search Examples
Operation Connect a Servo Driver and execute an origin search based on the Servomo-
tor's built-in encoder phase-Z signal and a Origin Proximity Input Signal.
Conditions • Operating mode: 1
(Uses the Servomotor encoder's phase-Z signal as the Origin Input Sig-
nal.)
• Origin search operation setting: 0
(Sets reverse mode 1. Reverses direction when the limit input signal is
input in the origin search direction.)
• Origin detection method: 0
(Reads the Origin Input Signal after the Origin Input Signal goes
OFF→ON→OFF.)
• Origin search direction: 0 (CW direction)
