9.5 Modification Function of Control
9.5.1 Floating Origin Setting
This is used to force to set the current position as the origin without carrying out the homing action of the machine.
(1) Characteristic of Control
(a) Modify the current position into “Homing end position” of homing parameter and become Origin-decided
status.
(b) After floating origin setting command is executed, the current position is changed to “The position of homing
completion” of homing parameter.
(c) Related parameter (Homing Parameter)
Items Setting value Description
Position of homing
completion
-2147483648 ~ 2147483647
Set the position after homing completion or floating
origin setting
Note
Floating origin setting just executes forced origin-decision from the current position to origin completion
position. So user need to take notice as follows.
1. When error arose, clear the cause of error and reset,
2. set floating origin again,
3. change the operation step no. to operate with start step no. change command and then execute.
