47.8 Integral action time Iq
For description, see Z47.7–.
47.9 P-Gain 4kHz Id
The proportional gain (Kp) of the Id current controller is set with the P-gain 4kHz Id pa-
rameter. Correspondingly, the reset time (Tn) of the Id current controller is set with the
Integral Action Time Id parameter (
Z47.10–). According to the optimum magnitude and
taking account of the internal standardizations, Kp and Tn for the Id current controller at
4 kHz PWM frequency can be set as follows:
T
n
= L
sd
/ r
s
(msec)
where r
s
= Stator resistance in ohms, cold
k
p
= L
sd
/(3*Tab) = L
sd
/(3*0.125) = 2.667* L
sd
(L
sd
in mH)
For asynchronous motors, the total leakage inductance L
sigma
must be used instead of
L
sd
.
47.10 Integral action time Id
For description, see Z47.9–.
47.20 Usq set value
Displays the control variable for the iq controller, taking account of the feedforward.
47.21 Usd set value
Displays the control variable for the id controller, taking account of the feedforward.
47.22 Integral term Usq
Displays the integration terms of the control variable for the iq controller.
