PARAMETER
(1) Selection of control method and control
mode
1) FR-A700 series
Select the inverter control method from 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).
When vector control test operation ([ Pr. 800 = 9 ]) is
selected, speed control test operation can be
performed without the motor 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 terminal FM and AM.
