Torque Current Limitation [95] - WEG CFW-11 Programming Manual

Vector Control
Description:
This parameter is automatically adjusted during the self-tuning. The P0413 setting determines the speed regulator
gains (P0161 and P0162).
When P0408 = 1 or 2, it must be observed:
If P0413 = 0, the time constant T
(table value).
If P0413>0, the value of P0413 will not be changed by the self-tuning.
Sensorless vector control (P0202 = 3):
When the P0413 value obtained through the self-tuning provides inadequate speed regulator gains (P0161
and P0162), it is possible to change them by setting P0413 via keypad (HMI).
The P0161 gain provided by the self-tuning or through P0413 change, will be limited to the range:
6.0≤P0161≤9.0.
The P0162 value varies in function of the P0161 value.
In case it be necessary to increase even more these gains, they must be adjusted directly at P0161 and P0162.
Note: Values of P0161>12.0 may turn the torque current (I
Vector control with encoder (P0202 = 4):
The load may be coupled to the motor shaft for this step of the routine.
The P0413 value is estimated by the self-tuning when P0408 = 3 or 4.
The measurement procedure consists in accelerating the motor up to 50 % of the rated speed, applying a current
step equal to the motor rated current.
When it is not possible to estimate P0413 using the self-tuning function (in applications of cranes, position control
and others), adjust P0413 via keypad (HMI). Consult
