Field data
6.1 Field control
P082 = 0: Internal field is not used
(e.g. with permanent-field motors)
P082 = 1: The field is switched together with the line contactor
(field pulses are enabled/disabled when line contactor closes/opens)
P082 = 2: Automatic connection of standstill field set via P257 after a delay parameterized via
P258, after operating status o7 or higher has been reached
P082 = 3: Field current permanently connected
6.2 Field weakening
P081 = 0: No field weakening as a function of speed or EMF
P081 = 1: Field weakening operation as a function of internal EMF control so that, in the field
weakening range, i.e. at speeds above rated motor speed (= “threshold speed”),
the motor EMF is maintained constantly at setpoint
EMFset (K289) = P101 – P100 * P110.
