Control word for field characteristic
0 No valid field characteristic has yet been recorded
1 Valid field characteristic (P118 to P139 valid)
The parameter is set automatically during the field-weakening optimization
run (P051=27).

P118
FDS
Rated EMF value
(see also Section 8, Sheet G165)
EMF that is reached with a full field (according to parameter P102) and a
speed as set in parameter P119.
The parameter is set automatically during the field-weakening optimization
run (P051=27) and specifies in this case the setpoint EMF in the field-
weakening range.
Note:
As regards the closed-loop field-weakening control, only the ratio between
P118 and P119 is relevant. The EMF setpoint in the field-weakening range
is determined by (P101 – P100 * P110). When the setting in P100, P101 or
P110 is changed subsequently, the field-weakening optimization run need
not be repeated. However, P118 then no longer defines the setpoint EMF in
the field-weakening range.
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.

P119
FDS
Rated speed
Speed at which an actual EMF value as set in parameter P118 is reached
at 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
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).
