Setting Up Parameters

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 programmed 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 programming resolution.

Acceleration Group

Time Scale List Box

From this list box, select the acceleration time scale to be used for all real-time profiles. The
time scale selected will be used for both acceleration and deceleration parameters. You can
select from milliseconds or seconds.

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 accel/decel parameters throughout the software. Using a
high number of decimal places will improve accel/decel resolution, but will also limit the
maximum accel/decel rate. You can select from zero to six decimal places of programming
resolution.

Torque Group

Units Name

10-character name for the torque user units.
