Parameter
ranges
and
variable
maximums:
The
two
values
provided
define
the
minimum
and
maximum
values
for
the
given
parameter.
In
some
cases
the
parameter
range
is
variable
and
dependant
on
either:
•
other
parameters,
•
the
drive
rating,
•
or
a
combination
of
these.
The
values
given
in
Table
4-1
are
the
variable
maximums
used
in
the
drive.
