Table 9: IFD control parameters for the connected motors
Description
Parameter
Rated frequency:
Rated frequency of the connected motor (current rating).
C015
Rated voltage:
rated voltage of the connected motor (voltage rating).
C019
V/f curve type:
Type of V/f curve applied.
C013
Torque reduction with quadratic curve:
Torque reduction using V/f quadratic curve.
C032
Rated speed referring to torque reduction with quadratic curve:
Speed actuating the torque reduction using a quadratic curve.
C033
Voltage preboost:
Determines the voltage produced by the drive at min. output frequency fomin.
C034
Voltage Boost 0:
Determines the voltage variations in respect to the nominal voltage at the frequency set up by the
relevant parameter.
C035
Boost 0 application frequency:
Determines the Boost 0 application frequency.
C035a
Voltage Boost 1:
Determines the frequency for the application of the boost at preset frequency.
C036
Boost 1 application frequency:
Determines the Boost 1 application frequency at preset frequency.
C037
Autoboost:
Variable torque compensation expressed as a percentage of the rated motor voltage. The preset
value expresses the voltage increase when the motor is running at rated torque.
C038
