Re bit 01 (not for permanent-magnet synchronous motors):
Initially, the flux is only established with a low rate of rise when magnetizing the induction motor. The flux setpoint
p1570 is reached again at the end of the magnetizing time p0346. When quick magnetizing (p1401.6 = 1) is
selected, soft starting is internally de-activated and alarm A07416 is displayed.
The flux differentiation can be switched out if a significant ripple occurs in the field-generating current setpoint
(r0075) when entering the field weakening range. However, this is not suitable for fast acceleration operations
because then, the flux decays more slowly and the voltage limiting responds.
Re bit 02 (not for permanent-magnet synchronous motors):
The flux build-up control operates during the magnetizing phase p0346 of the induction motor. If it is switched out, a
constant current setpoint is injected and the flux is built up corresponding to the rotor time constant. When quick
magnetizing (p1401.6 = 1) is selected and when flux build-up control is de-energized alarm A07416 is displayed.
Re bit 06 (not for induction motors):
Magnetizing is performed with maximum current (0.9 * r0067). With active identification of the stator resistance (see
p0621) quick magnetizing is internally de-activated and alarm A07416 is displayed. During a flying restart of a rotat-
ing motor (see p1200) no quick magnetizing takes place.
Re bit 07:
if the speed of the drive exceeds the effective speed limit of the speed limiting controller, the torque limit is reduced
linearly to zero as the deviation becomes greater. This reduces the integral component of the speed controller and,
in turn, the overshoot during load shedding (see also F07901 and p2162).
