Origin Regression Mode Introduction(Must be in internal position mode)
A. Origin trigger start mode(P4-34)
The origin trigger start mode is divide into two kinds of origin regression function. One is
automatic performing and another is contacting trigger. Details as below:
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.
B.
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)
