• Function
These parameters are used to switch between two different types of motors connected
to the inverter or to change the
characteristic of the motor according to the use conditions or operation mode.
Note: The RV parameter (V/F control mode selection) is effective only for motor 1.
If motor 2 is selected, V/F control will be selected regardless of the setting of the
RV parameter (V/F control mode selection).
6.3 Basic parameters 2
6.3.1 Switching motor characteristics via input terminals
H : Base frequency 2 (Hz)
H : Base frequency voltage 2 (V)
H : Torque boost 2 (%)
H : Motor thermal protection level 2 (%)
■ Parameter setting
Title Function Adjustment range Default setting
H Base frequency 2 (Hz) 25～200(Hz) *1
H Base frequency voltage 2 (V) 50～500 *2
H Torque boost 2 (%) 0.0～30.0(%)
Depends on the model.
(See Section 11.)
H Motor thermal protection level 2 (%) 30～100(%) 100
*1. *2. The value is changed according to the set-up parameter condition.
(VFNC1 (S)-□□□□P□-W type)
*1 60 [Hz] for VFNC1 (S)-□□□□P□ type.
*2 200 [V] for VFNC1 (S)-□□□□P□ type.
■ Setting of switching terminals
The function of switching from motor 1 to motor 2 is not assigned by default to any terminal. So,
assign this function to an unassigned terminal if necessary.
Parameters to be switched vary depending on the function number selected with an input terminal
selection parameter.
