5.2.2 Floating Origin Setting Instruction
• Floating origin setting refers to setting the current position as the origin by force with the instruction
without carrying out the actually mechanical origin return.
(1) Floating origin Setting Instruction (FLT)
[Area Setting]

Description

Data size
sl
Slot number where positioning module is
mounted
XGB is fixed at 0 WORD

Description
Device number
Error
If the value of ax gets out of the range
F110
(a) Function
• This instruction is for setting the floating origin to the XGB built-in positioning.
• The instruction of setting the floating origin is given to the axis designated as ax of XGB positioning
at the rising edge of the input condition.
• If the instruction is carried out, the current position address becomes 0, and the origin determining
bit (axis X: K4204,axis Y:K4304) turns On.
(b) Error
• If the value designated as ax (instruction axis) is other than 0 and 1, the error flag (F110) is set and
the instruction is not executed
Remark
• Floating origin setting presets the current position at 0 and only fixs the origin, so you need to
note the following when you use the instruction of setting the floating origin.
 Check whether there is an error before carrying out the floating origin setting instruction. If
there is an error, remove the cause of the error, reset the error (CLR instruction) and
terminate the output inhibition.
 Now set the floating origin, change the step number to operate into the starting step change
instruction (SNS), and then get it started.
