4 B3 External regeneration resistor connection
terminals
If regenerative energy is high, an external regeneration resistor is connected so that the
regenerative energy can be absorbed.
When an internal regeneration resistor is used:
B1 and B2 are open, B2 and B3 are short-circuited

.
When an external regeneration resistor is used:
The external regeneration resistor is connected between B1 and B2, B2 and B3 are open.
*2
B2 and B3 shall be short-circuited in the factory setting.
