■ Precision Settings for Auto-Tuning
Basic motor nameplate data can be used to auto-tune a motor. However, improved
performance can be achieved by using precise data for base voltage and base
frequency. If the base no-load voltage and frequency are known, enter this data
when executing auto-tuning to improve performance.
◆ No-Load Operation
This section explains how to operate the drive with the motor uncoupled from the
load during a test run. Performing the test run is necessary to confirm that the auto-
tuned parameters generate the desired motor performance.

Iron Loss
Provides the iron loss for determining the Energy
Saving coefficient.
When power is cycled, the value set to E2-10 will
appear (the motor iron loss). If T1-02 is changed, an
initial value for the motor capacity will appear that is
close to the capacity that was changed.

<1> Select motor 2 to display this selection.
<2> Voltage and frequency settings for a vector motor or drive motor are often lower than for standard
motors. Be sure to enter Auto-Tuning data according the motor nameplate and Motor data sheets. If
the no-load voltage and frequency values are known, enter those values into T1-03 and T1-05
<3> The default setting for this parameter is determined by the drive capacity (set by parameter o2-04).
