P4-34=0
: close origin regression function. When set P4-34=0, the origin regression function can
not work not matter what its setting value is.
P4-34=1
: when the power is on, it will execute origin regression automatically. The function is
available one when the power supply and servo on,which means it is unnecessary to repeat the
operation when the servo works. It can save one input contact used to perform the origin
regression.
P4-34=2
: It triggers origin regression function through the input contact SHOM.
One of registers which are input pin function planning register must be set to SHOM trigger
input function. The SHOM contact can be triggered at any time during the servo working and the
function of origin regression can be performed.

Origin trigger start mode(P4-32)
The origin detector can use either the left limit switch or the right limit switch as the reference
point for the origin. Or it can use extra detectors such as near type or light-gate type switch) as
the reference. The Z pulse can be also set as a reference point when the servo motor moves in
only one revolution.
P4-32=0
: CW direction finds the origin and use CCWL limit as a rough reference point. When
completing origin positioning, CCWL is limit input function. The subsequent retrigger will occur
limit warning. When using limit input point as a rough reference point, recommended to set Z
pulse(P4-33) as the precise mechanical origin.
P4-32=1
: CCW direction finds the origin point and use CWL limit as a rough reference point.
CWL is limit input function.The subsequent retrigger will occur limit warning. When using limit
input point as a rough reference point, recommended to set Z pulse(P4-33) as the precise
mechanical origin.
P4-32=2
: CW direction finds the origin point and use ORGP(external detector input point) as the
origin point reference. Then Z pulse of return search(P4-33=0) or do not return search(P4-33=1)
can be set as the precise mechanical origin point. If do not use Z pulse as the mechanical origin
point, the positive edge of ORGP can be also set as the mechanical origin point(P4-33=2).
P4-32=3
: CCW direction finds the origin point and use ORGP(external detector input point) as
the origin point reference. Then Z pulse of return search(P4-33=0) or do not return
search(P4-33=1) can be set as the precise mechanical origin point. If do not use Z pulse as the
mechanical origin point, the positive edge of ORGP can be also set as the mechanical origin
point(P4-33=2).
P4-32=4
: CW direction finds Z pulse origin point directly. This function is usually used for servo
