13.20.10 Manual field weakening
A manual field weakening can be achieved via MCTRL_nFldWeak_a.
ƒ For a maximum excitation MCTRL_nFldWeak_a has to be activated by +100 %
(= 16384).
ƒ If MCTRL_nFldWeak_a is not connected (free), the field weakening automatically is
+100 %.
(
Stop!
If the field is weakened manually (MCTRL_nFldWeak_a < 100 %), the drive
cannot produce the maximum torque.
