ST (±) nnnnnnnn
STA (±) nnnnnnnn
(The + sign can be
omitted.)
Positioning Start (Absolute Position)
Setting range: −99999999 ≤ nnnnnnnn ≤ [phone] [Reference units]
Specifies the absolute position nnnnnnnn as the target position and starts positioning at the same
time. This command is equivalent to the following combination:
POSA + nnnnnnnn → ST
Example:
SPDnnnnnnnn: Positioning Speed Specification
STA + nnnnnnnn: Target Position Specification and Positioning Start
∗ When the target position is an absolute position, the axis will not move if the same position-
ing is repeated with ST.
OK
STI (±) nnnnnnnn
(The + sign can be
omitted.)
Positioning Start (Relative Position)
Setting range: −99999999 ≤ nnnnnnnn ≤ [phone] [Reference units]
Specifies the relative distance nnnnnnnn as the target position and starts positioning at the same
time. This command is equivalent to the following combination:
POSI + nnnnnnnn → ST
Example:
SPDnnnnnnnn: Positioning Speed Specification
STI + nnnnnnnn: Target Position Specification and Positioning Start
OK
