3. The inverter will output the value that B, C voltage (refer to 10-0) plus 10-1 V/F pattern setting.
And the start torque will be raised.
※ Note: 10-1=0, Torque boost function is invalid
4. When the induction motor is in running, there must be slip due to the load. It is necessary to boost to
improve the precision of the speed.
Slip frequency boost =

Motor synchronization speed (RPM)=
eg: 4 Poles ， 60Hzinduction motor synchronization speed =
※ Note: Motor no load current(10-2) differs with the inverter capacities （ 15-0 ） (Refer to 0-02 note) ，
It should be regulated according to the actual condition.
