Lenze i550 - Optimising the Stalling Behaviour

10.4.7 Opmising the stalling behaviour
If the motor is driven with frequencies above the rated motor frequency, the operang point
is shied to the "eld weakening range". In this range, the motor voltage does not increase
proporonately to the output frequency anymore. As a consequence, the inverter automa-
cally reduces the maximum current since the full torque is not available anymore at these fre-
quencies.
For special motors which enable an operaon in the eld weakening range, the behaviour in
the eld weakening range can be adapted to the motor with 0x2B0C (P319.00).
DANGER!
Danger by incorrect parameterisaon.
Possible consequences: damage to material assets and injury to persons
▶
Only change the default seng (0 Hz) in 0x2B0C (P319.00) aer consulng the motor man-
ufacturer!
▶
Recommendaon: Maintain default seng (0 Hz).
The funcon is equally suitable for the closed loop V/f characterisc control.
