 Function
Use the above parameters to switch the operation of two motors with a single inverter and to select
motor V/F characteristics (two types) according to the particular needs or operation mode.
Note: The  (V/F control mode selection) parameter is enabled only for motor1.
If motor 2 is selected, V/F control will be given constant torque characteristics.
