Note: A value of 100% corresponds to the motor rated slip (r0330).
The setting of the starting frequency begins after magnetizing (see p0346, r0056.4) and ends once the brake open-
ing time (p1216) has elapsed and the starting frequency (p1334) has been reached.
A setting value of zero means that no setting procedure will take place.
Description: Sets the configuration for the closed-loop speed control.
Note: Re bit 01:
When the bit is set, the I component of the speed controller is kept when changing into the open-loop controlled
mode.
Description: Sets the configuration for flux setpoint control
Note: Re 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.
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.
