2.6 The connection of brake resistor
When the internal brake resistor is used, it is necessary to short circuit B1 and B2 (as the
picture A shows); while for the driver models as picture B shows, they can be used directly as
they deliveried from factory.
PictureA PictureB
When the external brake resistor is connected to the servo driver, the short circuit wire
between B1 and B2 must be disconnected fiestly, and then crossover the external brake resistor
to terminals P and B1 (for the driver models as picture C shows); but for the servo driver models
as picture D shows, the internal brake resisitor wire between terminals P and B must be
disconnected, and connect those two wires to NC at the same time. Then crossover the external
brake resistor to terminals P and B.
