Setting for other Motors
The
VXM
can
be
used
with
motors
not
listed
in
the
table
on
the
previous
page.
Motors
that
are
compatible
with
the
VXM
must
meet
the
following
criteria:
Two
important
specifications
are
needed
about
the
motor
to
be
used
with
the
VXM.
The
motor’s
Unipolar
per
phase
current
rating
in
amps,
and
the
motor’s
inductance
rated
in
Millihenries
(MH.)
Refer
to
the
motor
manufacturer’s
data
sheet
to
obtain
this
information.
Multiply
the
current
(I)
times
the
inductance
(L)
to
arrive
at
a
product
value
(IxL)
to
compare
in
the
table
below.
1.
6 or 8 wire permanent magnet step motor
2.
Motor rated at a unipolar per phase current of 0.4 to 4.7
Amps
If
the
motor
you
want
to
use
does
not
meet
the
above
requirements,
STOP!The
motor
is
not
compatible
with
the
VXM.
When
determining
the
VXM
value
x
from
the
table
below,
the
motor
must
be
within
both
the
current
range
and
the
IxL
product.
CAUTION:
THE VXM MUST BE SET CORRECTLY
BEFORE OPERATING.
IMPROPER SETTINGS CAN CAUSE SEVERE DAMAGE TO MOTORS
AND
CONTROLLER.
