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 load, increase the tor que boost, but
the torque boost should not be set too big, which will resul t 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 i s 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.

V/F slip compensation limit 0.0 200.0%
F1.23
Setting this parameter can compens ate the motor speed change produced because of undertaking
loading while on V/F control, to increase the ri gidity of motor mechanical performance. This value
should be set as the motor rated slip frequenc y.
