The HD2IP series inverter provides dedicated function codes for SVPWM control mode. Users
can improve the performance of SVPWM through settings.
1.
Torque boost
Torque boost function can effectively compensate for the low-speed torque performance during
SVPWM control. Automatic torque boost has been set by default to enable the inverter to adjust
the torque boost value based on actual load conditions.
Note:
(1) Torque boost is effective only under torque boost cut-off frequency.
(2) If the torque boost is too large, low-frequency vibration or overcurrent may occur to the
motor, if such situation occurs, lower the torque boost value.

2. Energy-saving run
During actual running, the inverter can search for the max. efficiency point to keep running in
the most efficient state to save energy.
Note:
(1) This function is generally used in light load or no-load cases.
(2) This function does fit in cases where load transient is required.
3.
V/F slip compensation gain
SVPWM control belongs to open-loop mode, which will cause motor speed to fluctuate when
motor load transients. In cases where strict speed requirement is needed, users can set the slip
compensation gain to compensate for the speed variation caused by load fluctuation through
internal output adjustment of inverter.
