Chapter 5 Data Used for Positioning Control
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 sequence 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.
(1) If the set command speed exceeds "[Pr.8] Speed limit value", positioning will
be carried out at the speed limit value.
(2) 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 "No command speed"
(error code: 503) will occur, and the positioning will not start.
Refer to Section 16.4 "List of errors" for details on the errors.)

1: The command speed setting range is 0.001 to 2000000.000[degree/min], but it will be decupled
and become 0.01 to 20000000.00[degree/min] by setting "[Pr.83] Speed control 10 x multiplier
setting for degree axis" to valid.
