Origin Search Operation Section 8-2
G-series Origin Search Parameters
W-series Origin Search Parameters
Note When using a Position Control Unit with unit version 2.0 or later, the Final Dis-
tance for External Input Positioning for G-series Servo Drives (Pn203) or Final
Travel Distance for External Positioning for W-series Servo Drives (Pn814) is
used for internal processing in the Position Control Unit for either of the follow-
ing origin search operation patterns.
• When the origin detection method is set to any value except for 0
(Origin proximity input signal reversal)
• When setting a zero point position offset for an origin search using an
absolute encoder
The Final Distance for External Input Positioning for G-series Servo Drives
(Pn203) or Final Travel Distance for External Positioning for W-series Servo
Drives (Pn814) is automatically overwritten by the Position Control Unit when
the origin search operation is started. If interrupt feeding is used after the ori-
gin search, the
Final Distance for External Input Positioning for G-series
Servo Drives (Pn203) or Final Travel Distance for External Positioning for W-
series Servo Drives (Pn814) must be reset. Also, the Servo parameters are
read out by the Position Control Unit for the following parameters when the
origin search operation is started.
Origin Return Approach Speed 1, Origin Return Approach Speed 2, Origin
Return Final Distance
(Pn110, Pn111, and Pn204) for G Series or Zero Point
Return Approach Speed 1 , Zero Point Return Approach Speed 2 , and Final
Travel Distance to Return to Zero Point (Pn817, Pn818, and Pn819) for W
Series)
