If AxisName(AxesGroupName).Pr.Unit_Position is HFD010000 and
AxisName(AxesGroupName).Pr.Unit_Velocity is HFD000300, [mm/ms] is displayed on
AxisName(AxesGroupName).Md.Unit_VelocityDisplay.
If AxisName(AxesGroupName).Pr.Unit_Position is HFF000000 (An arbitrary unit character string), number of
displayable characters from the beginning out of the position command unit character strings is displayed on
AxisName(AxesGroupName).Md.Unit_VelocityDisplay.
If "1" is set in the program when AxisName(AxesGroupName).Pr.Unit_Velocity is HFD000300, the velocity will
be regarded as 1.0 [position command unit]/ms.

Combination of command units during multiple axes positioning control
Set command units of the axes group and the interpolation axis to be matched.
When the command units are mismatched, specify the input value of FB as shown below.
• For the input regarding position in multiple axes positioning control (Position, Distance input, etc.), the value based on the
position command unit of the each interpolation axis is required to specify. Refer to the following for details.
Page 227 Position (Target position)/Distance (Movement amount)
• For the input of Velocity, Acceleration, Deceleration and Jerk in multiple axes positioning control, the value based on the
velocity command unit used for each control is required to specify. Refer to the following for details.
Page 228 Velocity (Velocity)
Velocity command units used for each control are shown below.
The following operations depend on interpolation controls.

Operation
• The combined movement amount is calculated from the value of the current position and the Position/
Distance input. The position command unit of the axes group and the interpolation axis are not affected.
• Unit of the axes group is used for the velocity command unit in controling.
• The axis whose movement amount value is the largest is regarded as the long axis from the value of the
current position and the Position/Distance input. The position command unit of the axes group and the
interpolation axis are not affected.
• The unit of the long axis is used for the velocity command unit in controlling.Unit of the axes group is not
used.
The unit of the reference axis (First element of LinearAxes input) is used for the velocity command unit in
controlling.
