regeneration but the maximum regenerated armature voltage will be reduced.
When 1, the armature voltage is measured across motor terminals MA1 and MA2.
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
