regenerative
resistor
terminals
R70F, R90F, 2R1F, 2R8F,
R70A, R90A, 1R6A, 2R8A
If the regenerative capacity is insuffi-
cient, connect an external regenerative
resistor (option) between B1/
and B2.
3R8A, 5R5A, 7R6A, 120A,
180A, 200A, 330A, 1R9D,
3R5D, 5R4D, 8R4D, 120D,
170D
Remove the lead or short bar that is short-
circuiting between B2 and B3, and con-
nect an external regenerative resistor
between B1/
and B2 only if the inter-
nal regenerative capacity is insufficient.
Purchase an external regenerative resistor
separately.
470A, 550A, 590A, 780A,
210D, 260D, 280D, 370D
Connect a regenerative resistor unit
between B1/
and B2. Purchase a
regenerative resistor unit separately.
