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 fi 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
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

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.
