is
connected
to
four
‐
wire
and
eight
‐
wire
motor
as
follows:
0
Note:
When
the
drive
is
connected
with
motors
of
other
companies,
the
pin
colors
may
be
different.
In
actual
wiring,
measure
the
lead
category
with
a
multimeter
before
wiring
to
prevent
damage
to
the
motor
or
drive.

Wiring
requirements
¾
To
prevent
interference
with
the
drive,
the
control
signals
use
shielded
cable,
which
is
single
‐
grounded.
One
end
of
the
shielded
cable
PC
is
grounded,
and
the
drive
of
the
shielded
wire
is
vacant.
A
machine
only
can
be
grounded
at
the
same
point.
If
it
is
not
true
ground
wire,
it
may
cause
serious
interference,
and
the
shield
layer
doesn’t
need
to
be
connected.
¾
Pulse
and
direction
signal
lines
can’t
be
bound
together
with
motor
lines,
but
should
be
separated
at
least
10cm,
or
else
the
motor
noise
is
easy
to
interfere
with
pulse
direction
signal
and
cause
failures
such
as
inaccurate
electrical
positioning
and
instable
system.
¾
If
one
power
supply
is
provided
to
multiple
drives,
they
should
be
connected
to
the
power
supply
in
parallel
rather
than
in
chain.
¾
Do
not
plug
or
unplug
strong
electric
terminal
CN1
of
electrified
drive,
the
electrified
motor
still
has
large
current
flowing
through
the
coil
when
stopped,
and
plugging/unplugging
CN1
terminal
will
lead
to
huge
moment
induced
emf
and
burn
the
drive.
