47.2 sd set value
Display of the limited Isd set value which is passed directly to the current controller.
47.3 Isq actual value
Display of actual value of Isq.
47.4 Isd actual value
Display of actual value of Isd.
47.5 Isq actual value filtered
Filtered actual value of Isq (time constant = 1.25 ms).
47.6 Isd actual value filtered
Filtered actual value of Isd (time constant = 1.25 ms).
47.7 P-Gain 4kHz Iq
The proportional gain (Kp) of the Iq current controller is set with the P-gain 4 kHz Iq pa-
rameter. Correspondingly, the reset time (Tn) of the Iq current controller is set with the
Integral Action Time Iq parameter (
Z47.8–). According to the optimum magnitude and
taking account of the internal standardizations, Kp and Tn for the Iq current controller at
4
kHz PWM frequency can be set as follows:
T
n
= L
sq
/ r
s
(msec)
where r
s
= Stator resistance in ohms, cold
k
p
= L
sq
/(3*Tab) = L
sq
/(3*0.125) = 2.667* L
sq
(L
sq
in mH)
For asynchronous motors, the total leakage inductance L
sigma
must be used instead of
L
sq
.
