tive resistor connec-
tion terminals
R70F, R90F, 2R1F,
2R8F, R70A, R90A,
1R6A, 2R8A
If the regenerative capacity is insufficient, connect
an external regenerative resistor between B1/ and
B2.
Note: The external regenerative resistor 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.
470A, 550A, 590A,
780A, 210D, 260D,
280D, 370D Connect a regenerative resistor unit between B1/
and B2.
Note: The regenerative resistor unit is not included.
