Parameter
Selection of control method and control mode
Select the inverter control method for V/f control, advanced magnetic flux vector control (speed
control), real sensorless vector control (speed control, torque control) and vector control (speed
control, torque control, and position control).
Pr. 80,
Pr. 81
≠ 9999
9999
Tab. 6-2: Selection of control method
Control method is V/f control regardless of the setting value of Pr. 800 when "9999" is set
in Pr. 80 "Motor capacity" or Pr. 81 "Number of motor poles".
Vector control test operation (Pr. 800 = 9)
Speed control test operation can be performed even when the motor is not connected. The
speed calculation value changes to track the speed command and the transition can be checked
with the operation panel and analog signal output at CA and AM.
NOTES
Since current is not detected and voltage is not output, monitors related to current and volt-
age such as output current and output voltage, etc. and output signals do not function.
For speed calculation, speed is calculated in consideration of Pr. 880 "Load inertia ratio".
