Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: For bit 01:
When the bit is set, the I component of the speed controller is kept when changing into the open-loop controlled
mode.
For bit 16:
When the bit is set, the integral component of the speed controller is only held if it reaches the torque limit.
For bit 20:
The acceleration model for the speed setpoint is only active for encoderless vector control if p1496 is not zero.
For bit 25:
When the bit is set, for high dynamic starting in the I/f mode, the acceleration precontrol torque smoothing only has a
short minimum time (4 ms).

Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: For bit 00 (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.
For 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.
For 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.
