P 2.4.5 Over Modulation
Use the parameter to enable or disable overmodulation of the output voltage. Select [1] On to obtain extra DC-link voltage and torque
on the motor shaft. Select [0] Off to avoid torque ripple on the motor shaft.

Selection description
To avoid torque ripple on the motor shaft, select [0] Off for no
overmodulation of the output voltage. This feature may be useful
for applications such as grinding machines.
Select [1] On to enable the overmodulation function for the
output voltage. Select this setting when it is required that the
output voltage is >95% of the input voltage (typical when
running oversynchronously). The output voltage is increased
according to the degree of overmodulation.
NOTICE
Overmodulation leads to increased torque ripple as
harmonics are increased.
