A33 (Nominal Elevator Speed E07)
This parameter displays the calculated nominal elevator motor speed in rpm. Alternatively this parameter can be used to manually set-up the nominal
elevator speed in rpm. This nominal elevator speed rpm is used to set the motion profile scaling such that distances calculated for the profile in mm
will result in the elevator car positioning correctly in the scaled mm units.
The nominal elevator speed rpm is derived using the following calculation:
A = (B x D x E x 60) / (Pi x C x F)
Where:
A = A33 (Nominal Elevator Speed rpm E07)
B = A28 (Nominal Elevator Speed mm/s E01)
C = A29 (Sheave Diameter E02)
D = A30 (Roping E03)
E = A31 (Gear Ratio Numerator E04)
F = A32 (Gear Ratio Denominator E05)
A34 (Maximum Motor Speed E08) must be set >
A33 (Elevator Speed rpm E07)
A34 (Motor Maximum Frequency Clamp E08)
(Motor Maximum Speed Clamp E08)
The maximum motor speed parameter allows the user to define a maximum frequency (Open loop) or speed (RFC-A, RFC-S) for the motor. For
Open loop and RFC-A there are default settings configured for both European defaults at 50 Hz and USA defaults at 60 Hz. During operation where
the motor maximum speed may be exceeded due to a loss of control the drive will generate an Over Speed trip.
