F1.2 2 Torque boost cut-off
rated frequency)
Torque Boost is mainly applied to less than cut-off frequency (F1.22). The V/F curve after boost is
shown in following figure. Torque booth can improve the low frequency torque performance of V/F control.
Based on the load, a torque should be chosen properly. For heavy loa d, increase the tor que boost, but
the torque boost should not be set too big, which will result in the motor operating at overexcitation and
that it could be overheated, and also the inverter output current is big, reducing efficiency.
When the torque boost is set as 0.0%, the inverter is at automatic torque boost.
Torque boost cut-off frequency: below this frequency, torque boost is valid, and above this frequency
setting, torque boost is invalid.

F1.23 V/F sli p compensation limit 0.0 200.0%
Setting this parameter can compensate the motor speed change produced because of undertaking
loading while on V/F control, to increase the rigidity of motor mechanical performance. This value
should be set as the motor rated slip frequency.
