The firing angle end stop may be too close to the voltage crossover point. Parameter allows the user to increase the safety margin during
regeneration but the maximum regenerated armature voltage will be reduced.
When 0, the armature voltage is a measurement which is dependent on the setting of Pr 5.16.
When 1, the armature voltage is measured across motor terminals MA1 and MA2.
This parameter is used to scale the current demand such that the control loop correctly predicts the firing angle in the discontinuous current region.
This should be automatically setup by autotune.
Pr 5.15 = 29.5 x V rms / (L x f x Imax)
Where :
L is the load inductance in Henries
R is the load resistance in ohms
f is the supply frequency in Hertz
Imax is the peak load current (including any overload) in amps
V rms is the line-to-line supply voltage in volts.
The source for the armature voltage feedback is determined as follows:
