Parameters 161
23.05 Acc comp DerTime Defines the derivation time for acceleration/(deceleration)
compensation. In order to compensate inertia during
acceleration, a derivative of the reference is added to the
output of the speed controller. The principle of a derivative
action is described for parameter
23.03 Derivation time .
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:
Acceleration compensation:
0.00 … 600.00 s Acceleration compensation derivation time. 100 = 1 s
23.06 Acc comp Ftime Defines the derivation filter time constant for the
acceleration(/deceleration) compensation. See parameters
23.03 Derivation time and 23.05 Acc comp DerTime .
Note: This parameter is automatically set by the speed
controller autotune function (when performed in User mode).
See parameter 23.20 PI tune mode .
