Note1: Jumper settings are only updated following a reset or POR of the drive.
Note2: If no jumpers are installed on JP1, JP2 and JP3, the parameters will be set via software.
Note 3: If using jumpers in Sine Mode with minimum settings (no jumpers), install a jumper on JP1-G to
force the drive to use the jumper settings. This prevents the drive from using software settings as
described in Note 2.
