The reduced 󹪞ux in the motor partial load range results in higher e󹪟ciency.
Parameters
The converter calculates the parameters for the thermal motor model based on the motor data
that has been set – and the motor data identi󹪝cation.
E󹪟ciency optimization, method 2
Parameter Description Setting
p1401.14 Flux control con󹪝guration 1 signal: E󹪟ciency optimization 2 active
Factory setting: 0000 0000 0000 0110 bin
p1570[0...n] CO: Flux setpoint [%] Sets the 󹪞ux setpoint referred to rated motor 󹪞ux.
Factory setting: 100
p3315[0...n] E󹪟ciency optimization 2 minimum
󹪞ux limit value [%]
Sets the minimal limit value for the calculated op‐
timum 󹪞ux.
Factory setting: 50
p3316[0...n] E󹪟ciency optimization 2 maxi‐
mum 󹪞ux limit value [%]
Sets the maximum limit value for the calculated
optimum 󹪞ux.
Factory setting: 110
E󹪟ciency optimization, method 1
Parameter Description Setting
p1570[0...n] CO: Flux setpoint [%] Sets the 󹪞ux setpoint referred to rated motor 󹪞ux.
Factory setting: 100
p1580[0...n] E󹪟ciency optimization [%] 0 %: E󹪟ciency optimization is deactivated.
100 %: In no-load operation, the converter reduces
the 󹪞ux setpoint to 50% of the rated motor 󹪞ux.
The factory setting depends on the converter.
7.29 Calculating the energy saving for 󹪞uid 󹪞ow machines
Overview
Fluid 󹪞ow machines, which mechanically control the 󹪞ow rate using valves or throttle 󹪞aps,
operate with a constant speed corresponding to the line frequency.
