Activate table: P435[0] - CON_FM_FWMode = TABLE_MOT_GEN(4)
Parameter P-343 CON_FM_ImagTab can be used to configure 16 elements.
Index 0-7: Motor or classic table,
Index 8-15: Regenerative; the speeds are the same in both cases
The selection concerning as of what power the operation mode is “motor-oriented”
or “regenerative” is defined by P-459 MOT_PNom * P-348 CON_FM_SlipCon (%).
For small power values, linear interpolation between the tables is employed.

7.7.4Variant5(TABLE2)
“Table 2” has 8 data points for the field-weakening current component with an
equidistant spacing between two limit speeds.
Activate table: P435[0] - CON_FM_FWMode = TABLE2(5)
The lower limit speed is P 342[0] - CON_FM_SpeedTab[0], and the upper limit
speed is P 342[1] - CON_FM_SpeedTab[1]. Both numerical values for the limits
speeds are standardized relative to the nominal speed of the motor (MOT_SNom).
The table values for the field-weakening current component (-id) are specified via
P 343 - CON_FM_ImagTab[0..7] and standardized to sqrt(2)*CON_FM_Imag. The
interpolation values are calculated using linear interpolation.
P 343 - CON_FM_ImagTab[0] and CON_FM_ImagTab[7] are used for extrapolation
outside of the limit speeds.
