12 DATA USED FOR POSITIONING CONTROL
12.4 Positioning Data

■ When "[Pr.1] Unit setting" is "inch"
The table below lists the control methods that require the setting of the arc address and shows the setting range.
(With any control method excluded from the table below, the arc address does not need to be set.)
*1 Set an integer because the program cannot handle fractions.
(The value will be converted properly within the system.)
*2 Note that the maximum radius that circular interpolation control is possible is 536870912 (

inch), although the setting value can be
input within the range shown in the above table, as an arc address.
[Da.8] Command speed
Set the command speed for positioning.
• If the set command speed exceeds "[Pr.8] Speed limit value", positioning will be carried out at the speed limit value.
• If "-1" is set for the command speed, the current speed (speed set for previous positioning data No.) will be used for
positioning control. Use the current speed for uniform speed control, etc. If "-1" is set for continuing positioning data, and
the speed is changed, the following speed will also change.
Note that when starting positioning, if the "-1" speed is set for the positioning data that carries out positioning control first, the
error "Command speed is not set" (error code: 1A12H) will occur, and the positioning will not start.
Refer to the following for details on the errors.
