Note: Re bit 00 (only for induction 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.
Re bit 01 (only for induction motors and separately excited synchronous motors):
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 (only for induction 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 03:
The load-dependent calculation of the flux characteristic is available for separately-excited synchronous motors.
Re bit 04 (only for induction motors with encoder):
The flux controller does not operate in the range of the current model and not in the range of the flux impression
(refer to p1750.4).
Re bit 05 (only for induction motors with encoder):
Extremely rugged control operation is possible by directly toggling between the current model and flux impression.
We therefore recommend that, in addition, the time-controlled model change is switched in (p1750.4 = 1) or the
model changeover limits are significantly increased (p1752 > 0.35 * p0311; p1753 = 5 %).
Re bit 06 (not for induction motors):
Magnetizing is carried out with the maximum current (0.9 * r0067 <= p1603 * r0209). Magnetization has been
completed if the flux threshold value p1573 or the magnetizing time p0346 has been reached. 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 rotating 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).
Re bit 08:
The speed limiting controller sets the speed to maximum by opening the torque limits as far as the current limits (bit 8
= 0) or taking the torque limits into account (bit 8 = 1).
