P30: 110 - IM: sensor-less control (SLC), V/f characteristic
The motor is magnetized (flux-formation, P781) and, if selected, a starting current
(P623) is impressed. The IxR compensation compensates the voltage drop at the stator
resistor.

P621
P part (2.00)
For sufficient torque if a high start torque is re-
quired. The start current is impressed until the
output frequency reaches the value of P624.
P622
I part (50 ms)
P624
Frequency Limit (2.60 Hz)
The starting current is impressed up to this output frequency.
P780
Max. Flux-Formation Time (300 ms)
The current during flux-formation (value of P781) is not impressed longer than this
time.
P781
Current during Flux-Formation (value: I
FIN
)
Upon startup, this current value is impressed. The time for current impression is limited
by P780.
