Note: Re bit 19, 20:
When this bit is set, speed overshoots when accelerating along the torque limit and for load surges are reduced.
Re bit 20:
The acceleration model for the speed setpoint is only active if p1496 is not zero.
Description: Sets the configuration for the closed-loop speed control.
Note: Re bit 19, 20:

Re bit 20:
The acceleration model for the speed setpoint is only active if p1496 is not zero.
Description: Sets the configuration for flux setpoint control
Note: Re bit 01:
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.
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:
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.
Re bit 06:
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.
