Rated motor power
Enter the rated power of the motor.
Unit: hp
Value range: 0.0...125 hp
Default setting: 5.0 hp
Adjustment value: in accordance with the motor name plate
The power value is calculated from the torque and speed. Therefore
this parameter becomes read only.

Parameter Description - Motor Data
Unit: rpm
Value range : 10.0....6000.0 or 500.0
(based on con g mode)
Default setting: 1165.0 or 150.0
(based on con g mode)
Adjustment value: in accordance with the motor name
plate
You may not enter the motor-synchronous speed (e.g. 1800
rpm for a 4 pole motor, 1200 rpm for a 6 pole motor, and 900
rpm for a 8 pole motor). Ask the manufacturer for the motor
rated speed if you cannot  nd it on the name plate or use
the following example to estimate the rated speed.
Example: If the name plate reads 1200 rpm (synchronous
speed) then the value that should be entered must
be lower. For starting purposes, one can estimate
the slip at about 2.9%. Then through running the
elevator it is possible to determine whether further
adjustments are necessary. 2.9% of 1200 is 35 rpm.
So for starting, use the value 1200 - 35 = 1165 rpm
which is the default value.
From this parameter along with the rated frequency in LF.13,
the COMBIVERT Elevator Drive calculates the number of motor
poles. As a result there are
limits as to how low the value
can be adjusted for a motor
with a certain number of poles.
Refer to the table to the right
for the valid adjustment range
of 60Hz motors.
