Function/Description
Target Position Specification (Absolute Position)
Setting range: −99999999 ≤ nnnnnnnn ≤ +99999999 [1 reference unit]
Specifies the target position as an absolute position.

Note: If a new target position is specified during positioning, the new target position
will be used in the next ST command.
Target Position Specification (Relative Distance)
Setting range: -99999999 ≤ nnnnnnnn ≤ +99999999 [1 reference unit]
Specifies the target position as a relative distance.

Note: If a new target position is specified during positioning, the new target position
will be used in the next ST command.
Positioning Speed Specification
Setting range: 1 ≤ nnnnnnnn ≤ +99999999 [1000 reference units/min]
Specifies the positioning speed.
After the control power supply is turned ON, the positioning speed set in
parameter PnB27 will be used until the SPD command is executed.
For example, when the reference unit is 0.01 mm and the desired speed is
15 m/min:
15 m/min = 15000 mm/min
= 15000 × 100 reference unit/min
= 1500 [1000 reference unit/min]
SPD1500
Note: If a new positioning speed is specified during positioning, the new speed will
become effective from the next positioning.
When the target position is
an absolute position, the axis
will not move if the same
positioning is repeated with ST.
