Starting behaviour (V/f)
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.

P623 Starting Current (value: I
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.
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
Upon startup, this current value is impressed. The time for current impression is limited
by P780.
