≤
nnnnnnnn
≤
+99999999 [1 reference unit]
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

Setting range:
-
99999999
≤
nnnnnnnn
≤
