Default
Update rate
The programmable value of the armature back emf or armature voltage (standalone
mode), in volts, at which the field begins to weaken. Defined as the voltage at which
base speed is reached.

Update rate
The calculated voltage being generated on the field output terminals. Calculated from
applied mains voltage and firing angle.

Default
Update rate
Gains used during field weakening. Setting these too high could cause instability during
field weakening.

When this parameter is set to OFF (0) the field controller operates with the field
weakening voltage loop. When set to On (1) the flux level is determined by reference on
terminal 3.
