The acceleration time of V/F separation voltage refers to the time required for the
output voltage to accelerate from 0 to the rated voltage of the motor， the deceleration
time of V/F separation voltage refers to the time required for the out voltage to decelerate
from motor rated voltage to 0 .

6.6 Vector Control Parameters
Vector control regulator is divided into speed control regulator and torque control
regulator：Speed control mode is that the whole control takes the stable speed as the core
to ensure that the running speed is consistent with the speed reference, and the maximum
load capacity is limited by the torque limit；torque control mode is the whole control to
stabilize the torque as the core to ensure that the actual output torque and torque
reference consistent, and the output frequency is limited by speed limit.
