double-click the coordinate system.
2. On the Coordinate System Properties dialog box, on the General tab,
select Cartesian as the Type .
3. Click the Dynamics tab.
Use the settings on the Dynamics tab in the Coordinate System Properties
dialog box to enter Vector, Actual and Command Position Tolerance, and
Orientation values for a Cartesian coordinate system.
The Dynamics tab is only available when configuring a Cartesian coordinate
system.

The settings on the Dynamics tab in the Coordinate System Properties dialog
box are used to enter vector, position and tolerance, and orientation values for a
Cartesian coordinate system.
The Vector values are used by the Coordinated Motion instructions in
calculations when the operands are expressed as percent of Maximum. The
Coordination Units automatically change when the coordination units are
redefined on the Units tab.
The Orientation values are used by the Motion Coordinate Path Move (MCPM)
instruction. These values are always in units of degrees, and only available when
System Type is Cartesian and Coordinate Definition is <none>.
Parameter Description
Vector Maximum Speed The value used by the Coordinated Motion instructions to calculate vector speed when speed is
expressed as a percent of maximum.
Vector Maximum Acceleration The value used by the Coordinated Motion instructions to determine the acceleration rate to
apply to the coordinate system vector when acceleration is expressed as a percent of maximum.
Vector Maximum Deceleration The value used by the Coordinated Motion instructions to determine the deceleration rate to
apply to the coordinate system vector when deceleration is expressed as a percent of maximum.
The Maximum Deceleration value must be a non-zero value to achieve any motion using the
coordinate system.
