Protects
the
power
supply
line
by
shutting
the
circuit
OFF
when
an
overcurrent
is
detected.
Eliminates
external
noise
from
the
power
line.
Connect
an
external
regenerative
resistor
to
terminals
B1
and
B2
if
the
rgenerative
capacity
is
insufficient.
Turns
the
servo
ON
and
OFF.
Install
a
surge
suppressor.
