Emerson FM-3 manual Acceleration Group, Time Scale List Box, Separate Distance Units Example

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.
