Internal field is not used and field functions are not used.
(e.g. with permanent-field motors)
The field is switched together with the line contactor
(field pulses are enabled/disabled when line contactor closes/opens)
Automatic connection of standstill field set by P257 after a delay parameterized by P258,
after operating status o7 or higher has been reached
Field current permanently connected
No field weakening as a function of speed or EMF
Field weakening operation as a function of internal EMF control so that, in the field
weakening range, i.e. at speeds above motor base speed, the motor EMF is maintained
constant. Note: Rated EMF = Rated Terminal voltage – I
EMF (K289) = P101 – P100 * P110.
setpoint
Motor current limit in torque direction I (in % of P100, default value = 100%)
US setting P171 = 150%
Motor current limit in torque direction II (in % of P100, default value = -100%)
US setting P172 = -150%
Acceleration time 1 (in seconds, default value = 10)
Deceleration time 1 (in seconds, default value = 10)
Initial rounding 1 (in seconds, default value = 0)
Final rounding 1 (in seconds, default value = 0)
