Velocity Group
Enable Separate Distance Units Check Box
If checked, separate distance and velocity units, name and scaling will be enabled. If not
enabled, the velocity units, name and scaling will be defined by the Distance Group.
Scaled Distance Name
If the user wants the velocity units to have a different distance scaling than the distance units
a name can be entered here up to 10 characters. For example, the user distance units could be
inches while the velocity units are feet per minute.
Velocity Distance Units Scale Factor
This parameter scales the Velocity Distance Units back to actual distance units. To do this,
enter the number of distance user units that are equal to one velocity scaled distance unit.
Separate Distance Units Example:
A user has an application using a leadscrew with a 0.5"/turn lead. The user wants to have
Distance Units of Inches, but wants Velocity Units of Feet so motion can be programed in
feet/minute.
Distance Units Name —> Set to Inches
Enable Separate Distance Units —> Enabled (checked)
Scaled Distance Name —> Set to Feet
Velocity Distance Units Scale Factor —> # of Distance Units / 1 Scaled Distance Unit
1 Foot = 12 Inches
=> Velocity Distance Units Scale Factor = 12
Time Scale List Box
The time can be one of two values: seconds or minutes. This selection sets the real-time
velocity time scale.
Decimal Places
The number of decimal places set in this parameter determines the number of digits after the
decimal point used in all real-time velocity parameters throughout the software. Using a high
number of decimal places will improve velocity resolution, but will also limit the maximum
velocity. You can select from zero to six decimal places of accuracy.
