6.4 Basic parameters #2
6.4.1
Switching among V/f characteristics #1, #2, #3 and #4 from input terminal
 ：Base frequency #2
 ：Base frequency voltage #2
 ：Manual torque boost #2
 ：Motor overload protection level #2
 ：Base frequency #3
 ：Base frequency voltage #3
・Function
These parameters is useful for - for example - when 4 motors are connected to a
single inverter and thus they need to be switched from time to time to operate or
there is a need to change V/f characteristics (#1 to #4).
1) Switching with input terminal
2) Switching by parameter settings => Refer to 6.29.6.
Note) The setting of the parameter  (V/f control mode selection) is valid only when V/f #1 is
selected. If V/f #2, V/f #3 or V/f #4 is selected, V/f control is performed in constant torque mode.
Do not switch motors when the parameter  (Motor control mode selection) is set at 7, 8 or 9.
For parameters selected when changing V/f characteristics (1 to 4), refer to table on the next
page.
■Setting of switching terminals
The V/f #1, V/f #2, V/f #3 and V/f #4 switching function is not yet assigned to any terminal.
Therefore, it is necessary to assign them to unused terminals.
Ex.) Assigning the V/f switching #1 function to S1 and the V/f switching #2 function to S2.
