wire
If the capacity of the internal regenerative resistor is
insufficient, remove the wire between B2 and B3 and
connect an external regenerative resistor to terminals
B1 and B2.
For Servopacks with a capacity of 6.0 kW or higher,
connect an external regenerative resistor between
terminals B1 and B2 (There is no terminal B3 on
these Servopacks.)
