Setting range
0 ~ 200
During deceleration, over excitation control can suppress bus voltage increase, avoid over voltage fault.
The bigger over excitation gain is, the better the suppression result is.
For the application which over voltage fault happens frequently during deceleration, the over excitation
gain needs to be increased. But the current would be increased if the over excitation is too bigger, so you
need to set the suitable over excitation gain.
For the small inertia situation, voltage doesn’t increase during motor deceleration, please set over
excitation gain to 0. For the application with braking resistor, please also set over excitation gain to 0.

In the speed control mode, the maximum of the inverter output torque is controlled by the torque upper limit
source.
A2-47 is used to select the setting source of torque upper limit. When setting via the analog value, high
speed pulse HDI, communication, 100% of the relevant setting corresponds to A2-48, and 100% of A2-48
is the inverter rated torque.

PI regulation parameters of vector control, the parameters will be got automatically after autotunning, in
normal condition, they are unnecessary to be modified.
Note: if the PI gain values are set too big, it will cause the control be oscillation, while the current oscillation
