resistor connection
terminal
100 0.03 to 0.2
Normally not connected.
Connect an external regenerative resistor (provided
by customer) between B1 and B2 if the regenerative
capacity is insufficient.

B3
200 0.5 to 5.0
Normally short B2 and B3 (for an internal regenera-
tive resistor).
Remove the wire between B2 and B3 and connect an
external regenerative resistor (provided by customer)
between B1 and B2 if the capacity of the internal
regenerative resistor is insufficient.
