With the example values, the following results are obtained:
Preliminary Numerator
Preliminary Denominator
The values calculated in this way can be used directly for parameters
tor Numerator
the following intermediate "Optimization" step is recommended. This intermediate
step is not necessary if accuracy is already sufficient.
EC2 Gear Factor Numerator
EC2 Gear Factor Denominator
8the step: Optional: Optimization of gear factors
The steps carried out above will result (provided that calculation was made correctly)
in a denominator which is smaller than the numerator. This advantage is used for
optimization.
The following is set:
EC2 Gear Factor Numerator
Value 300.00 is always used to achieve maximum accuracy.
Conclusive
With the example values, the following results are obtained:
EC2 Gear Factor Numerator
EC2 Gear Factor Denominator
Note:
9th step: Optional: Check of accuracy:
This section describes the calculations required for determining the accuracy. The
check is not required for proper function, it is solely for determining the accuracy lim-
its.
Due to rounding operations in the parameters described above, there will be an error
across the total travel distance. This error is calculated in the following steps:
) 1 ( Distance
( ) 2 Distance
( ) 3 Distance
