11.4 Specific settings for induction motors in open loop (geared motors without encoder)
For induction motors auto tuning has to be performed before the first travel. The brake stays applied. To do so, the
parameters described in the table below must be set.

P01
Motor number of poles from manufacturer data sheet or motor name plate
Must be set before setting F03 value!

Depends on the
motor
F03
Motor’s rated speed (from motor’s name plate). The units are always rpm (not
dependant on C21 setting). Normally F03 is motor speed at nominal lift speed
1500 rpm
Depends on the
motor
L31
Maximum linear (in m/min) speed corresponding to F03 value. Used as
linearization factor for speed settings
60.0
Depends on the
installation
F04
Motor’s synchronous speed. The units depend on the setting of function C21.
For 4-pole motors (50Hz) is 1500 r/min, for 6-poles motors (50Hz) is 1000 r/min

P06
Motor no-load current in A. The Auto tuning procedure calculates, the value of
this function (when P04=3). The calculation overwrites the factory setting

P07
Motor stator resistance (R1) in %. The Auto tuning procedure measures the
value of this function (when P04=1 or 3). The measurement overwrites the

P08
Motor stator reactance (X1) in %. The Auto tuning procedure measures the value
of this function (when P04=1 or 3). The measurement overwrites the factory

P12
Slip frequency in Hz. The Auto tuning procedure measures the value of this
function (when P04=3). The measurement overwrites the factory setting

Auto tuning procedure (executed from input terminals) in 5 steps
To perform the described procedure the enable (EN1&EN2) inputs must be active.
1. Is the motor correctly connected?
2. Turn on inverter mains supply
3.
Please set the functions described in the above table
4. Set function P04 to 3 and press FUNC/DATA
5. Give RUN command to the inverter from the lift controller (normally in INSPECTION mode). The main
contactors will be closed and current will flow through the motor producing some acoustic noise. This
procedure will take some seconds. After this auto tuning procedure is finished.
