When in current mode the flux demand from the field weakening voltage loop, subject to the limits of Pr 5.68 and Pr 5.69.
When in voltage mode [Pr 5.75=On (1)] the voltage demand is subject to the limits of Pr 5.68 and Pr 5.69.
Indicates the field current feedback in 0.01 amps.
The range is 0 to 150 % in half control mode for the internal field controller.
0° equals fully phased forward.
The programmable value of the armature back emf, in volts, at which the field begins to weaken.
Defined as the voltage at which base speed is reached.
The calculated voltage being generated on the field output terminals.
