Wiring and Connection
Do not open short-circuit B1
/
and B2 terminals. Doing so may damage the SERVO-
PACK.
The
1 and
2 is short-circuited with a jumper at the factory.

If the regenerative capacity is insuf-
ficient, connect an external regener-
ative resistor (option) between B1/
and B2.

If the regenerative capacity is insuf-
ficient, remove the wire or short bar
that shorts the connection between
B2 and B3, and connect an external
regenerative resistor (option)
between B1/
and B2.
550A, 260D
Connect a regenerative resistor unit
(option) between B1/
and B2.
