H3-xx: MFAI Function Selections

Setting Value	Function	Description	Ref.
0	Frequency Reference	The input value from the MFAI terminal set with this function becomes the master frequency reference.	Details

Setting Value	Function	Description	Ref.

Motor Temperature (NTC Input)

Set this parameter when you connect the motor thermistor. Detects the motor temperature and protects the motor.

Note:

When A1-02 = 3 [Control Method Selection = CLV], motor protection and compensation for slip caused by motor temperature is possible.
