6.3.1Switching 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 (%)

• 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				6
	RV parameter (V/F control mode selection).
■Parameter setting

	H	Base frequency voltage 2 (V)	50～500	*2
	H	Torque boost 2 (%)	0.0～30.0(%)	Depends on the model.

	*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.
