CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
P413
(1)
0.00 to 99.99
Tm Constant
[ 0.00 ]
(MechanicalTime
0.01 s
Constant)
The setting of P413 determines the gains of the speed regulator (P161
and P162).
When P408 = 1 or 2, observe the following:
-
If P413 = 0, then the Tm constant will be obtained as a function of the
motor inertia (memorystored value).
-
If P413 > 0, then the value of P413 will not be changed during the self-
tuning routine.
Sensorless Vector Control (P202 = 3):
When the value of P413 (obtained from the self-tuning routine) provides
unsuitable gains for the speed regulator, modifythis parameter to better
adjust the speed regulator gains.
The value of P161, provided by the self-tuning routine or through the
changing of P413, will be limited in the range: 6.0

P161

9.0.
The value of P162 varies according to the value of P161.
In case it is needed to increase more these gains, set them directly at
P161 and P162.
Note:
Valuesof P161> 12.0 maycause oscillations in the torque current
(iq) and in the speed.
Vector with Encoder Control (P202 = 4):
The value of P413 is estimated by the self-tuning routine when P408 = 3
or4. Incase itis notpossible to estimate it, thesetting shall be performed
manually. (Refer to P161/P162).
