2.2 List of parameters
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.
