6.2.15.1.1 Rated point determination
dr48 v/f characteristic mode defines the type of calculation of the rated point.

The v/f characteristic passes point dr06 rated frequency
/ dr05 rated voltage.
dr45 ASM v/f boost, dr46 ASM v/f V1 and mo32 ASM v/f
offset are values in % of the rated motor voltage dr05.

The v/f characteristic passes through point de30 inverter
rated voltage / projected rated point frequency.
dr45 ASM v/f boost, dr46 ASM v/f V1 and mo32 ASM v/f
offset are values in % of the inverter rated voltage de30.
The value dr48 determines the definition of the rated point (third point of the v/f
characteristic curve).
This point is directly defined at value 0 "use type plate data" by dr06 rated fre-
quency and dr05 rated voltage.
f (rated point) = dr06 rated frequency
U (rated point) = dr05 rated voltage
If dr48 is 1 "use inverter rated voltage“, the third point is calculated from the in-
verter rated voltage (de30 inverter rated voltage) and the motor data dr06 rated fre-
quency and dr05 rated voltage :
f (rated point = de30 inverter rated voltage / dr05 rated voltage * dr06 rated fre-
quency
U (rated point) = de30 inverter rated voltage
The reference value of the percentage voltage settings dr45, dr46 and mo32 is at
value 1 the rated inverter voltage instead the rated motor voltage.
6.2.15.1.2 0 Hz voltage
The voltage at frequency 0 Hz is defined with dr45 ASM v/f boost.
6.2.15.1.3 Additional point of support
The voltage of the v/f characteristic increases linearly with the frequency.
Two ranges with different voltage rise can be defined by using dr47 ASM v/f F1
and dr46 ASM u/f V1. If the additional point of support shall not be used, dr47 must
be set to zero. Then parameter dr46 has no function.
