Digital Position Mode
In Digital Position mode, you configure the amplifier for
a digital position loop driving a current loop.
Note: The current loop gains and limits apply to the
current loop operating inside the digital position loop. In
this mode, some of the values for motion profile and all of
the values for current loop are applicable.
