Autotune mode
Enabling the self-learning function of the electric parameters of the motor indicated in the group “Optional param". Activate this
mode to power drive but without enabling (Green LED RUN off), then you can enable the drive and the measurement phase takes
place (the RUN green LED flashes).
For more information on Autotune mode, see page 58.
Optional Param
Menu group with optional parameters that can be measured automatically by the “Autotune " procedure. If this procedure is not pos-
sible or if the motor parameters are known (provided by the manufacturer), they can be entered manually using the above menu group.

RPM
Set the rated motor speed as indicated on the plate. This value is the motor speed when powered by a three-phase network at the rated
frequency with the maximum load applied to the shaft. This parameter is optional and can be calculated automatically by the “Autot-
une" procedure.
Feedback Direction
With this parameter you can reverse the direction of counting of the transducer connected to the motor. The possible selections are as
follows:
•
NORMAL: The signal from the transducer is NOT inverted by sign.
•
REVERSE: The signal from the transducer is reversed by sign.
This parameter is optional and can be calculated automatically by the “Autotune " procedure.

Set the motor magnetising current or the unladen current that corresponds to the effective current required by the line when the motor
is powered by a three-phase line at a frequency equal to the “Nominal Frequency " in the absence of load connected to the shaft. This
parameter is optional and can be calculated automatically by the “Autotune " procedure.

Ω
Set the static motor resistance indicated by the manufacturer which corresponds to the equivalent resistor of a measured star connec-
tion between a phase and the star centre. This parameter is optional and can be calculated automatically by the “Autotune " procedure.
Magnetic induct

mH
Set the magnetic inductance of the motor indicated by the manufacturer. This parameter is optional and can be calculated automatic-
ally by the “Autotune " procedure.

mH
Set the motor leakage inductance indicated by the manufacturer. This parameter is optional and can be calculated automatically by the
“Autotune " procedure.
Drive Parameters
Menu group to set the main parameters of the drive grouped for faster adjustment. For a normal operating calibration with average
performance it is sufficient to adjust the parameters grouped here.
