Description
P119
Rated speed
Speed at which an actual EMF value as set in parameter P118 is reached at
FDS
full field (according to parameter P102).
This parameter is set automatically during the optimization run for field
weakening (P051=27) and specifies in this case the field-weakening
(G165)
activation limit speed.
Note:
As regards the closed-loop field-weakening control, only the ratio between
P118 and P119 is relevant. When the setting in P100, P101 or P110 is
changed subsequently, the field-weakening optimization run need not be
repeated. However, P119 then no longer defines the field-weakening
activation limit speed.
When the setting in parameter P102 is changed subsequently, the field-
weakening optimization run must be repeated, the same applies if the
maximum speed setting is subsequently re-adjusted.
Magnetization characteristic (field characteristic)
Parameters P120 to P139 determine the curve shape of the magnetization characteristic (field characteristic) in normalized representation
(see example field characteristic below for further details).
Note:
When the setting in parameter P102 is changed subsequently, the field-weakening optimization run must be repeated, because this alters
the degree of saturation and thus the shape of the magnetization characteristic. (When parameter P100, P101 or P110, or the maximum
speed adjustment, is subsequently altered, the settings in P120 to P139 remain the same, but the values in P118 and/or P119 are
changed).
