98
Unit: 1
Value range: 1.00 ... 250.00
Default setting: Geared = 30.00
Gearless = 1.00
Adjustment value: in accordance with the gear name plate
The ratio can be determined by counting the revolutions of the
motor during one rev of the traction sheave.
Once the car is running on high speed, if the measured speed
is slightly above or below the contract speed, the gear ratio can
be changed slightly to compensate. Higher values in LF.22 will
increase the car speed, lower values will decrease the car speed.
Make very small changes at rst!

Gear reduction ratio
Enter the actual gear ratio. If the ratio is not known, see param-
eter LF.25 and enter the value from LF. 25 into LF.22
Unit: Inches
Value range: 7.00...80.00 in
Default setting: 24.00 in
Adjustment value: measure the sheave diameter
The following parameters relate to the machine data of the elevator. It is important
to enter the correct values, such that both the motor and the car run at the correct
speed.
This is the elevator contract speed.
The speeds adjusted in parameters LF.42...LF.47 are limited by
LF.20. Other internal values are calculated from LF.20.
With an analog speed signal the following is valid:
0 ... ±10V = 0 ... ±contract speed (LF.20)
Unit: feet per minute
Value range: 0...1600ft/min
Default setting: 0 ft/min
Adjustment value: maximum speed of the system
If the motor does not run at the correct speed do not adjust
this parameter! See parameter LF.22.
