11.1.1.1 Starting Current
Configurations 110, 111 and 410, 411 and 430 for control of a 3-phase machine use
the starting current impression in operation modes 2, 4, 12 and 14 for the parameter
Operation Mode 620. The Starting Current 623 guarantees, in particular for heavy
starting, sufficient torque until the
Frequency Limit 624 is reached.
Applications in which high current is permanently needed at a low speed are to be
realized using forced-ventilated motors for thermal reasons.

11.1.1.2 Frequency Limit
The
Starting current 623 is impressed in configurations 110, 111, 410, 411 and 430
for control of a 3-phase machine until the
Frequency Limit 624 is reached. Permanent
operating points below the frequency limit are only admissible if forced-ventilated mo-
tors are used. The transition to the control method of the selected
configuration 30
takes place above the frequency limit.

11.1.2 Flux Formation
Field-oriented control in the configurations 210, 211, 230, 410, 411 and 430 are based
on separate regulation of the flux-forming and torque-forming current components.
Upon startup, the machine is magnetized and a current is impressed first. With the
parameter
Current during Flux-Formation 781 the magnetization current I
sd
is set,
with the parameter
Maximum Flux-Formation Time 780 the maximum time for the
current impression is set.
The current impression is done until the reference value of the rated magnetizing cur-
rent is reached or the
Maximum Flux-Formation Time 780 is exceeded.
