450 [Total Inertia]
Represents the time in seconds, for a
motor coupled to a load to accelerate
from zero to base speed, at rated motor
torque. The drive calculates Total Inertia
during the autotune inertia procedure.
Adjusting this parameter will cause the
drive to calculate and change [Ki Speed
Loop] and [Kp Speed Loop] gains.
