Fig.6-15 Torque increase (the increase amount is the shaded part)
 Note
1. Improper setting of this parameter may cause motor over-temperature or over-current protection.
2. For the definition of fz, please refer to function code P07.08.
3. The maximum output voltage Vmax corresponds to the motor rated voltage, so it is necessary to correctly
set the motor rated voltage based on the motor selected .
P07.09~P07.15 are used to determine different V/F curves of motor 2 under different V/F control modes.
The same as P07.07 and P07.08.
When the motor can not run normally due to the oscillation, increase this gain properly. The larger the
gain is, the more obvious the suppression on the oscillation will be. The gain value should be as small as
possible while effective motor oscillation suppression shall be ensured.
