The actual speed is supplied from the "Actual EMF" channel (K0287),
but weighted with P.
EMF at maximum speed
(1.00 to 140.00% of rated converter supply voltage (r078.001)).
The actual value input is defined with P609.
Number of connector to which actual speed controller value is connected.
Internal field is 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 via P257 after a delay parameterized via
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 rated motor speed (= "threshold speed"),
the motor EMF is maintained constantly at setpoint
EMFset (K289) = P101 – P100 * P110.
Motor current limit in torque direction I (in% of P100)
Motor current limit in torque direction II (in% of P100)
Torque limit 1 in torque direction I
(in % of rated motor torque)
Torque limit 1 in torque direction II
(in % of rated motor torque)
