Function
This parameter is used to switch V/f characteristics during operation or to drive
four motors with a single inverter.
This parameter is valid only when the inverter is in panel operation mode.
Switching by means of terminals
The V/f1, 2, 3 and 4 can also be switched by switching on and off terminals.
Refer to 6.4.1 for details.
