VFC Eco
Energy Saving Control for Asynchronous Motor (reduction of copper losses).
1. Set the motor control mode:
P300:0 to “VFC open Loop [6]”
2. Set the V/f characteristic shape:
P302:0 to “Eco [3]”
3. Advanced Motor setup:
Set motor parameter (6.5.12 Motor parameter, page 65) or select the motor out of the Lenze catalogue (In
case of a Lenze motor & Easy Starter).
4. Set VFC-ECO Minimum Voltage:
