19.4 A (Advanced) Parameter Details
A000
Control Mode
0000: Vector mode (Vector CT Mode)
0001: Vector mode (VT Mode)
0002: V/F mode
Select the appropriate vector control mode or V/F mode in accordance with the load characteristics.
1.) Vector (Vector CT mode) is best suited to control rapidly-changed torque loads.
2.) Vector (VT mode) is suitable for Fan and Pump loads. The magnetizing current of the motor
will vary with the torque, which will reduce the average current and save energy.
3.) If V/F mode is selected, set parameters, b009 and A129 - A137 in accordance with the load
characteristics.

Motor Parameter Auto Tuning
0000: Disabled
0001: Enabled
1.) Whenever the vector mode is selected, the motor nameplate data must be input to
parameters A001
– A005.
2.) The Auto tuning is performed by setting A006=0001. The detected internal data will
automatically be written to parameters A168 to A172 when the
display shows “End”.
Ex. If the motor rated speed is 1700 rpm, set A004 to 17.0
!
Caution
1. The motor parameter auto tuning is stationary auto tuning. During motor auto tuning, the motor
does not rotate, and the keypad displays
“-AT-”.
2. During motor parameter auto tuning, the input signal in the control circuit is invalid.
3. Before motor parameter auto tuning, confirm that the motor is stopped.
4. The motor parameter auto tuning is only available for vector control modes (A000 = 0000 or
A000 = 0001).
A007 AC Line Input Voltage (Volts)
230V Series : 170.0 - 264.0 Vac
460V Series : 323.0 - 528.0 Vac
To accurately represent the voltage level of the inverter, input the actual measured line voltage.
A010 Keypad Stop Button
0000: Stop Button Enable
0001: Stop Button Disable
When A010 = 0000, the STOP key is available on the keypad to activate a stop regardless of the drive Run source
as per parameter b000.
A011
Keypad Operation with Up/Down
Keys in Run Mode
0000:
‘Enter’ must be pressed after frequency
changes with the Up/Down Keys
on keypad to save selection.
0001: Frequency will be changed directly
when Up/Down Keys are Pressed
