Gearing FB

The Gearing FB is a linear equation with three arguments / parameters:

Output = (a × (input + b)) + c

'a'  - enter an Irrational Number, or a Ratio of two numbers.

Edit the Gearing FB:

1.Double-click the Gearing FB in the graphic-area.

Default output:

output motion-value = input motion-value

Output Function:

Three parameters:

The Gearing FB function is:

Output  = {1r×(Input +3r)}+ 2r

Ratio and Phase

1s-red Gearing Ratio [See also - below Gearing as 'Real' or 'Ratio' ]

2s Add after Gear Ratio

3s Add before Gear Ratio

Gearing as 'Real' or 'Ratio' 

4s Gearing Ratio:

Gearing as 'Real' - enter any number in the Gearing Ratio 1s-red

- or -

Gearing as 'Ratio' - enter integers in 5s & 6s


Gearing Ratio1s-red = Input-Pulley / Output-Pulley

5s Input-Pulley = ± Integer

6s Output-Pulley = ± Integer

Gearing Ratio becomes Read-Only


Gearing Ratio:

-1 > Gearing Ratio > 1 the output is 'stepped up', and becomes greater in magnitude than the input

-1 < Gearing Ratio < 1 ; the output is 'stepped down', and becomes less in magnitude than the input

Gearing Ratio < 0 ; the output is opposite to [negative of] the input.

Gearing Ratio = 1 ; the output is equal to the input

Gearing Ratio =-1 ; the output is equal, but the opposite to [negative of] the input

Connect a Gearing FB to the input of a Motion FB to change the number of times you complete a Motion in one Machine Cycle - Motion Frequency

Connect the output of a Motion FB to the input of a Gearing FB to change the amplitude of the motion - Motion Amplitude/Range.
