AXIS MANAGEMENT FUNCTIONS
2.1

Technical Units

The position command unit and the velocity command unit used in the motion control can be set in the "unit setting". Since the
unit can be specified freely depending on the control target, intuitive programming and monitoring are available.

Relevant variables

For the setting methods, refer to Help of the engineering tool.
Variable/Structure name
AxisName.Pr.
AxesGroupName.Pr.
Unit_Position
Unit_Velocity
Unit_PositionString
AxisName.Md.
AxesGroupName.Md.
Unit_PositionDisplay
Unit_VelocityDisplay

Setting methods

The position command unit and the velocity command unit can be set as the follows.

Details
Sets the position command unit to be used in the motion control.
Sets the velocity command unit to be used in the motion control.
Sets the command unit to be used in the motion control in a character
string. It is used when the position unit is set to HFF (an arbitrary unit
character string).
Outputs the position command unit that is being controlled in a character
string.
Outputs the velocity command unit that is being controlled in a character
string.
