Figure 8-16 Roping Ratio
Nominal Elevator Speed rpm (E07) is calculated automatically when Nominal Elevator Speed (E01), or Sheave Diameter (E02), or Roping (E03), or
Gearbox Ratio Numerator (E04), or Gear Ratio Denominator (E05) are modified.
See Nominal Elevator Speed rpm (E07) for more details.
This sets the gearbox ratio numerator and is used to calculate Nominal Elevator Speed rpm (E07). A gear box ratio (In:Out) of 7:3 is entered as 7 in
Gearbox Ratio Numerator (E04).
Nominal Elevator Speed rpm (E07) is calculated automatically when Nominal Elevator Speed (E01), or Sheave Diameter (E02), or Roping (E03), or
Gearbox Ratio Numerator (E04), or Gear Ratio Denominator (E05) are modified.
The default gearbox ratio of 1:1 is used for gearless PM motor applications.
See Nominal Elevator Speed rpm (E07) for more details.
This sets the gearbox ratio numerator and is used to calculate Nominal Elevator Speed rpm (E07). A gear box ratio (In:Out) of 7:3 is entered as 3 in
