A28 (Nominal Elevator Speed mm/s E01)
This parameter sets the elevator linear shaft speed (contract speed) in mm/s. This is used to set the motion profile scaling such that distances
calculated for the profile in mm will result in elevator car positioning in mm.
A29 (Sheave Diameter E02)
This parameter defines the motor sheave diameter in mm units and is used to calculate the nominal elevator speed rpm. See A33 (Nominal Elevator
Speed rpm E07) for more details.
A30 (Roping E03)
This parameter defines the roping ratio and is used to calculate the nominal elevator speed rpm. See A33 (Nominal Elevator Speed rpm E07) for
more details.
A31 (Gear Ratio Numerator E04)
This parameter defines the gearbox ratio numerator for geared Elevator systems and used to calculate the nominal elevator speed rpm. See A33
(Nominal Elevator Speed rpm E07) for more details. A gear box ratio of 7:3 is entered as 7 in gear ratio numerator. A default gearbox ratio of 1:1 is
used for gearless PM motor applications.
A32 (Gear Ratio Denominator E05)
This parameter defines the gearbox ratio denominator and is used to calculate the nominal elevator speed rpm. See A33 Nominal Elevator Speed
rpm (E07) for more details.
A gear box ratio of 7:3 is entered as 3 in gear ratio denominator. The default gearbox ratio of 1:1 is used for gearless PM motor applications.
