Restrictions
In the following case, an error occurs and the positioning will not start. During the positioning control, the operation stops
immediately at the detection of the error.
• If the movement amount of each axis exceeds 1073741824 (= 2
30
) when 0: Composite speed is set in [Pr.20] Interpolation
speed specification method, Outside linear movement amount range (Error code: 1A15H) occurs at the start of the
positioning. (The maximum movement amount that can be set in [Da.6] Positioning address/movement amount is
1073741824 (= 2
30
).)

Positioning data to be set
To use the 3-axis linear interpolation control (ABS linear 3), set the following positioning data.
 : Always set,  : Set as required,  : Setting not required
For details on the settings, refer to the following.

Page 420 Positioning Data
• If Reference axis speed is used for the 3-axis linear interpolation control, set the major axis as the reference
axis. If the minor axis is set as the reference axis, the speed of the major axis cannot be suppressed with
[Pr.8] Speed limit value.
• For the combinations of the reference axis and interpolation axes, refer to the following.
