Goodrive35 inverters Basic operation instruction
183
Goodrive35 series inverters provide multi-dots V/F curve, the user can change the output V/F
curve by setting the voltage and frequency of three middle dots. The whole curve is consisted of 5
dots. The starting dot is (0Hz, 0V), and the ending dot is (the basic frequency of the motor, the
rated voltage of the motor). During the setting processing: 0≤f

Goodrive35 series inverters provide special function code for SVPWM control mode which can
improve the performance of SVPWM control by means of setting.
1. Torque boost
Torque boost function can compensate the performance of low speed torque during SVPWM
control. The inverter will adjust the torque boost according to the actual load.
Note:
The torque boost takes effect only when the frequency is under the cap frequency of the boost.
If the torque boost is too big, low frequency vibration or overcurrent fault may occur. Please lower
the torque boost.
