13.4.3.3 User-denable V/f characterisc
The
"user-denable V/f characterisc" is provided for the individual adjustment of the motor
magnesaon to the actual applicaon if linear and square-law characteriscs are not suita-
ble.
•
The characterisc is dened by means of 11 parameterisable grid points (voltage/
frequency values).
•
In the Lenze seng the 11 grid points represent a linear characterisc:
