An

applied
to

parameters.
The

The
gain

the
position

controlled
with

parameter.
The
standard

are
in
2
32
counts

Although
it
is
possible
to
set
up
ratios
with
a
high
gain
or
even
with
a
denominator
of
zero,
the
drive
limits
the
resultant
gain
of
the
ratio
block
to
4.000.
the
standard
units
for
speed
are
0.1
rpm,
however
the
position
controller
gain
is
given
in
rads
-1
/rad.
These
units
are
consistent
with
units
such
as
mms
-1
/mm
or
ms
-1
/m
often
used
for
linear
control
applications.
An
error
of
1
radian
(10430
counts
in
the
position
error
(Pr
13.02))
gives
a
speed
reference
of
1rads
-1
(9.5
rpm)
when
this
gain
is
1.00.
