Increase the over-excitation gain if the AC drive is liable to overvoltage error during decelera-
tion. 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 F03.09.
If the torque upper limit is analog, pulse or communication setting, 100% of the setting corre
-
sponds to the value of F03.10, and 100% of the value of F03.10 corresponds to the AC drive
rated torque.
