Parameters 235
Defines the derivation time for acceleration(/deceleration)
compensation. In order to compensate for a high inertia load
during acceleration, a derivative of the reference is added to
the output of the speed controller. The principle of a derivative
action is described under parameter
.
Note:
As a general rule, set this parameter to the value
between 50 and 100% of the sum of the mechanical time
constants of the motor and the driven machine.
The figure below shows the speed responses when a high
inertia load is accelerated along a ramp.
No acceleration compensation:
