Set value corresponding
to input of inflection
point 2 of curve AI1
Maximum input of curve
AI1
Range: Input of inflection point
2 of curve AI1～100.0%
Set value corresponding to
maximum input of curve AI1
Curve AI1 is defined by above-noted 8 parameters.
Input values C2.00, C2.02, C2.04, C2.06:
AI1～AI2 are 0～10V or 0～20mA programmable by jumper on control board.
If 0～10V is selected: 0V corresponds to 0%, while 10V corresponds to 100%.
If 0～20mA is selected: 0mA corresponds to 0%, while 20mA corresponds to 100%.
AI3 only supports -10V～10V input; For AI3, -10V corresponds to -100%, while 10V corresponds
to 100%.
Corresponding set values C2.01, C2.03, C2.05, C2.07:
When the corresponding set value is frequency: 100% is the maximum frequency, while
-100% is the maximum negative frequency.
When corresponding set value is torque: 100% means 2 times the rated torque, while -100%
Means negative "2 times the rated torque".
When the corresponding set value is output voltage (e.g. the voltage setting in case of V/f
separated pattern): 100% corresponds to rated voltage of motor. "Less than or equal to 0%"
corresponds to 0V voltage.
