–
Improved smooth running at low
speed
– V/f ra t e d f re quency (C0015) and slip
(C0021) are calculated and stored.
They do not have to be entered
4 Vector control
For initial selection enter the motor data
5 Sensorless to rque control with speed limitation
• Torque setpoint via C0412/6
• Speed limit ation via setpoint 1 (NSET1-N1), if
C0412/1 is a ssigned, if not via max. frequency
(C0011)
and identify the motor parameters with
C0148
Otherwise commissioning is not
possible
