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.
Supposing that: Start = Low level and/or Fast stop = Low level
Set as field economy:
