I think I found it in this manual:
http://www.baldor.com.au/products/pd...D%20manual.pdf

Motor Frequency Multiplier Selection (J6) – Jumper
J6 is factory set to the “1X” position, for motor frequency
corresponding to the frequency setting of Jumper J5 (50
or 60 Hz). To double the output frequency to the motor,
set Jumper J6 to the “2X” position (100 or 120 Hz). See
Figure 14.
Note: When doubling the motor frequency, the motor
will produce full torque up to its rated speed. The torque
will be linearly reduced to 50% at the maximum doubled
frequency.

Am I right?

Have a closer look - practically all VFDs have a facility to
change this frequency. Low for maximum power handling and long
leads between VFd and load motor. Higher for minimum noise.

The data sheet is of no help.You need the full manual - there
may be as many as a 100 possible performance tweaks!

Names vary a bit - pulse frequency or carrier frequency are
the common ones. Some VFDs have a two tier menu system. The first
tier is easily accessible and contains the frequently used
control variables. The second tier contains the full range of
possibilities but can only be accessed after entering a special
access code.
