9.2.7 Opmising the stalling behaviour
If the motor is driven with frequencies above the rated motor frequency, the operang point
is shied to the
"eld weakening range". In this range, the motor voltage does not increase
proporonately to the output frequency anymore. As a consequence, the inverter
automacally reduces the maximum current since the full torque is not available anymore at
these frequencies.
For special motors which enable an operaon 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
parameterisaon.
Possible consequences: damage to material assets and injury to persons
▶
Only change the default seng (0 Hz) in 0x2B0C (P319.00) aer consulng the motor
manufacturer!
▶
Recommendaon: Maintain default seng (0 Hz).
