♦
During the standstill measurement P115 = 2, 3, the following
parameters are measured or calculated:
•
P103, P120, P121, P122, P127, P347, P349.
The controller settings resulting from these values are in: P283,
P284, P315, P316.
♦
During the rotating measurement P115 = 3, 4, P103 and P120 are
adjusted.
♦
During the n/f controller optimization P115 = 5, the parameters
P116, P223, P235, P236, P240 and P471 are determined.
In principle, automatic parameterization (P115 = 1) or motor
identification (P115 = 2, 3) should be carried out as soon as one of the
following parameters are adjusted in the converter status "Drive setting"
(P060 = 5):
P068 = Output filter
P095 = Motor type
P100 = Control type
P101...P109 = Motor rating plate data
P339 = Release of modulation system
P340 = Pulse frequency
P357 = Sampling time
In exceptional cases this is not necessary:
♦
If P068 is only adjusted between 0 and 2 (dv/dt filter).
♦
If P340 is adjusted in integer increments, e.g. from 2.5 kHz to
5.0 kHz...7.5 kHz... etc.
♦
If P339 is not set to overmodulated space vector modulation.
If P339 = 4 the modulation depth P342 must be additionally set to
approx. 90 %.
♦
If changeover is made between speed and torque control
(P100 = 4, 5).
♦
If changeover is made between speed and frequency control and
the following parameters are adapted:
f-control (P100 = 3) n-control (P100 = 4)
P315 = EMF Reg.Kp 2 x Kp Kp
P223 = Smooth.n/f(act) ≥ 0 ms ≥ 4 ms
P216 = Smooth. n/f(pre)
≥ 4.8 ms ≥ 0.0 ms
P222 = Src n/f(act) KK0000 KK0000 (KK0091)
The speed controller dynamic response may have to be reduced in the
case of encoder-less speed control (frequency control) (Reduce gain
(P235); increase Tn (P240)).
