gearchange9
Select from one two speed ranges
Usage
The output will be a value scaled for the selected gear, and clamped to the min/max values for that gear. The scale of gear 1 is assumed to be 1, so the output device scale should be chosen accordingly. The scale of gear 2 is relative to gear 1, so if gear 2 runs the spindle 2.5 times as fast as gear 1, scale2 should be set to 2.5.
Functions

Parameters
- gearchange.N.min1 float rw (default: 0)
-
Minimum allowed speed in gear range 1
- gearchange.N.max1 float rw (default: 100000)
-
Maximum allowed speed in gear range 1
- gearchange.N.min2 float rw (default: 0)
-
Minimum allowed speed in gear range 2
- gearchange.N.max2 float rw (default: 100000)
-
Maximum allowed speed in gear range 2
- gearchange.N.scale2 float rw (default: 1.0)
-
Relative scale of gear 2 vs. gear 1. Since it is assumed that gear 2 is "high gear",
scale2must be greater than 1, and will be reset to 1 if set lower.
- gearchange.N.reverse bit rw (default: 0)
-
Set to 1 to reverse the spindle in second gear.
