3. The inverter will output the value that B, C voltage (refer to 10-0) plus 10-1 V/F pattern setting.<br />
And the start torque will be raised.<br />

※Note: 10-1=0, Torque boost function is invalid<br />
4. When the induction motor is in running, there must be slip due to the load. It is necessary to boost to<br />
improve the precision of the speed.<br />
Output Current-(10-2) Note : 0-02=motor rated current<br />
Slip frequency boost =<br />

※Note: <strong>Motor</strong> no load current(10-2) differs with the inverter capacities(15-0)(Refer to 0-02 note),<br />
It should be regulated according to the actual condition.<br />
