V / f characteristic with which the inverter feeds the engine. The linear
characteristic corresponds to constant torque with variable speed. The
quadratic characteristic is normally used with centrifugal pumps. The
selection of torque characteristic should be done ensuring a smooth
operation, a reduction of energy consumption and a lower level of heat
and acoustic noise.
--->
If, during the test, the motor runs in reverse, it is possible to change the
wiring sequence via software without physically changing wires at the
terminals.
If the device is "FOC-ready", motor calibration must be carried out
before commissioning.
Carefully read the pertinent chapter.
Manual setting of the stator resistance.
Manual setting of the stator inductance.
Setting of the control dynamic of the FOC algorithm.
OFF
If ON is selected, after a lack of voltage, the device returns to its normal
status; if the unit was powering the pump before the voltage drop, it
resumes powering the pump automatically.
Warning, review the advice in chapter 1.
