Energy saving
1552 Energy Saving Function On
The signal at a digital input or a logic signal switches on the energy saving function. The digital input
or the logic signal must be selected for parameter
Energy Saving Function On 1552.
For parameter
Operation Mode Energy Saving Function 1550, "1 - manual" or "2 - automatic" must
be selected.

Off
No signal for switch-on of the energy saving function. Factory setting.
71 - IN1D
The signal at digital input IN1D (terminal X11.4) switches on the energy
saving function.
72 - IN2D
The signal at digital input IN2D (terminal X11.5) switches on the energy
saving function.
73 - IN3D
The signal at digital input IN3D (terminal X11.6) switches on the energy
saving function. For Operation Mode Terminal X11.6 558 "0 - Input
IN3D must be selected.
74 - IN4D
The signal at digital input IN4D (terminal X12.1) switches on the energy
saving function.
75 - IN5D
The signal at digital input IN5D (terminal X12.2) switches on the energy
saving function.
76 - MFI1D
The signal at multifunction input 1 (terminal X12.3) switches on the en-
ergy saving function. For Operation Mode MFI1 452 "3 - Digital NPN
(active: 0 V)" or "4 - Digital PNP (active: 24 V)" must be selected.
77 - MFI2D
The signal at multifunction input 1 (terminal X12.3) switches on the en-
ergy saving function. For Operation Mode MFI1 562 "3 - Digital NPN
(active: 0 V)" or "4 - Digital PNP (active: 24 V)" must be selected.
163 -
Reference Fre-
quency reached
The energy saving function is switched on if the frequency is reached.
164 -
Setting Frequen-
cy
The energy saving function is switched on if the value of Setting Fre-
quency
510 is reached.
8.2 Quadratic V/f characteristic
For applications where the torque increases quadratically to the speed, e.g. control of a fan, the pow-
er consumption can be reduced and energy can be saved. In the low speed range where the full
torque is not required, energy is saved.
Setting the quadratic V/f characteristic is possible if the following control method is selected for pa-
rameter
Configuration 30:
"110 - IM sensor-less control" (V/f characteristic)
606 Type V/f characteristic
Via parameter
Type V/f characteristic 606, you can switch the characteristic from linear to quadratic.
