Setting Up Parameters

Parameters Not Matching List

This list is part of the User Defined Motor Name Conflict dialog box and displays the parameter value(s) from the Motor Parameters column that do not match the equivalent parameter value in either the motor.ddf or stdmotor.ddf files, for the motor with the matching name.

This helps the user to determine whether they wish to overwrite, cancel, or create a new motor with this Save .ddf Values operation.

User Units View

The User Units View is used to scale the desired application units into known values. All information for distance, velocity, and accel/decel units are set up here and used throughout the system setup.

By selecting User Units in the Hierarchy Tree, the User Units View will appear on the right (see Figure 9).

Distance Group

Units Name

Select the type of units to be used throughout the configuration for all Position/Distance parameters. The default units are revs.

Decimal Places

This will specify the number of digits after the decimal place to be used in all distance/position parameters for the entire configuration.

Distance Scaling

This will specify the number of user units in 1.0000 motor revolution. This parameter also determines the resolution of distance/position parameters for the entire configuration. The number of decimal places specified here sets the maximum resolution.

For Example: If the user has a leadscrew with a 0.5" lead and wishes to perform indexes of 0.025", the Units Scaling must be set to 0.500. By specifying three digits after the decimal place, the user will be able to enter the three digits necessary for the index distance.

Velocity Group

Decimal Places

This will specify the number of digits after the decimal place to be used in all Velocity parameters.
