Title
 V/F control mode selection
Note:  (V/F control mode selection) is valid only for the first motor.
Changes to "V/F constant control" when switching to the second motor, regardless of the  setting.
Steps in setting are as follows
(In this example, the V/F control mode selection parameter  is set to  (Vector control).
[Setting V/F control mode selection to 3 (sensorless vector control)]
