P3.1.2.11 Under Volt. Control 0 1 1 608
0 = Disabled
1 = Enabled
P3.1.2.12 Energy optimization 0 1 0 666
The drive searches for the
minimum motor current in
order to save energy and to
lower the motor noise. This
function can be used e.g. in
fan and pump applications
0 = Disabled
1 = Enabled
P3.1.2.13 StatorVoltAdjust 50.0 150.0 % 100.0 659
Parameter for adjusting the
stator voltage in permanent
magnet motors.
P3.1.2.14 Overmodulation 0 1 1
Maximizes drive output volt-
age, but increases motor
current harmonics.
0= Disabled
1= Enabled
