If the regenerative c
apacity is insufficient, connect
an external regenerative resistor between B1/ and
B2.
Note: The external regenerative resisto
r is not
included.

If the internal regenerative resistor is
insufficient,
remove the lead or shorting bar between B2 and B3
and connect an external regenerative resistor
between B1/ and B2.
Note: The external regenerative resistor is not
included.
550A, 260D
Connect a regenerative resistor unit
between B1/
and B2.
Note: The regenerative resistor
unit is not included.
