*1 Use the variable torque patterns when there is a quadratic or cubic relationship between the speed
and load, such as in fan or pump applications. The user can properly choose the desired (V/f)
patterns (Sn-02=04, 05, 06, or 07) based upon the load torque characteristics.
*2 In the fan or pump applications, the load torque have a quadratic or cubic relationship between the
speed and load. The inverter capacity rating can be increased to a value that doubles its own
specified capacity rating in some special case. But, due to the real hardware limitation,
230 V 1HP,
2HP, 3HP, 10HP, 25HP, 40HP and 460 V 1HP, 2HP, 3HP, 30HP, 50HP can not be adapted any larger
capacity.
(4) V/F curve selection (Sn-02)
•
Set the inverter input voltage (Cn-01) first to match the power supply voltage. The
V/f curve can be set to ant of the following.
Sn-02 = 00~14: one of 15 pre-set curve patterns
= 15: V/F pattern can be set by the user through setting of Cn-01~Cn-08
