Learning Advanced Features
Sets the motor capacity to be used. The maximum motor capacity is limited
by the inverter capacity and the keypad only displays the inverter capacity.
Select an auto tuning type and run it. Select one of the options and then
press the [ENT] key to run the auto tuning.
Auto tuning function is disabled. Also, if you select
one of the auto tuning options and run it, the
parameter value will revert back to ‗0‘ when the
auto tuning is complete.
Measures all motor parameters while the motor is
rotating, including stator resistance (Rs), no-load
current (Noload Curr), rotor time constant (Tr), etc.
Since the motor is rotating while the parameters
are being measured, if the load is connected to the
motor spindle, the parameters may not be
measured accurately. For accurate measurements,
remove the load attached to the motor spindle.
Note that the rotor time constant (Tr) must be
measured in a stopped position.
Measures all parameters while the motor is in the
stopped position, including stator resistance (Rs),
no-load current (Noload Curr), rotor time constant
(Tr), etc. Since the motor is not rotating while the
parameters are measured, the measurements are
not affected when the load is connected to the
motor spindle. However, when measuring
parameters, do not rotate the motor spindle on the
load side.

Displays motor parameters measured by auto tuning. For parameters that
are not included in the auto tuning measurement list, the default setting will
be displayed.
• Perform auto tuning ONLY after the motor has completely stopped running.
• Auto tuning operates when the inverter‘s auto mode is off.
• Before you run auto tuning, check the motor pole number, rated slip, rated current, rated
voltage, and efficiency on the motor‘s rating plate and enter the data. The default parameter
setting is used for values that are not entered.
• When measuring all parameters after selecting 2 ( All-static type) at BAS-20: compared with
