14-03 Overmodulation

Default value: [1] On Parameter type: Option

Setup: All setups Conversion index: –

Data type: Uint8 Change during operation: False

Enable or disable the overmodulation function.

 NOTICE

Overmodulation leads to increased torque ripple as harmonics are increased.

Option Name Description

[0] Off 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.

[1] On 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.

14-04 Acoustic Noise Reduction

Default value: [0] Off Parameter type: Option

Setup: All setups Conversion index: –

Data type: Uint8 Change during operation: False

Enable or disable the acoustic noise reduction function.
