0.00 A / real32 Sets a custom motor current fault limit.
The drive automatically sets an internal motor current
limit according to the drive hardware. The internal limit
is appropriate in most cases, but this parameter can
be used to set a lower current limit, for example, to
protect a permanent magnet motor from
demagnetization.
Note: The limit defines the maximum peak current of
one phase.
With this parameter at 0.0 A, only the internal limit is
in force.
