Enable flux reg Enabling of the field converter
Enabled Field converter Enabled
Disabled Field converter Disabled.
The field current is zero
Flux reg mode Operating mode of the field converter .
Constant current The motor field works with a constant current. The current value
corresponds to the setting of the Motor nom flux parameter.
If any curve via the I field cnst parameters will be defined,
this value can be changed linearly, through Motor nom flux
(percentage of nominal flux Motor nom flux)
(see Flux /if curve paragraph 5.4.5)
Voltage control The drive works with a regulation combined with torque and
constant power (armature and field regulation). Via the Max
out voltage parameter in the CONFIGURATION menu, is set
the max. armature voltage.
External control The field is supplied through an external excitation (rectifier/field
converter).
Enable flux weak Command for Voltage control.
Enabled The field current corresponds to the value set via the Flux cur-
rent min parameter.
Disabled The field current is regulated on the basis of the functioning
mode and on the drive working setpoint.
Speed-0 f weak When this function is enabled, and the speed 0 threshold is reached, it will be produced
the minimum field current set via Flux current min.
