In the vector control mode, the output of the speed loop regulator is torque current reference. This parameter
is used to filter the torque references. It need not be adjusted generally and can be increased in the case of
large speed fluctuation. In the case of motor oscillation, decrease the value of this parameter properly.
If the value of this parameter is small, the output torque of the AC drive may fluctuate greatly, but the response
is quick.

During deceleration of the AC drive, over-excitation control can restrain rise of the bus voltage to avoid the
over voltage fault. The larger the over-excitation gain is, the better the restraining effect is.
Increase the over-excitation gain if the AC drive is liable to over voltage error during deceleration. Too large
over-excitation gain, however, may lead to an increase in output current. Therefore, set this parameter to a
proper value in actual applications.
Set the over-excitation gain to 0 in applications of small inertia (the bus voltage will not rise during deceleration)
or where there is a braking resistor.

In the speed control mode, the maximum output torque of the AC drive is restricted by P2-09.
If the torque upper limit is analog, pulse or communication setting, 100% of the setting corresponds to the
value of P2-10, and 100% of the value of P2-10 corresponds to the AC drive rated torque.
