CAUTION:
● If the transistors in the brake unit should become faulty, the resistor can be unusually hot,
causing a fire. Therefore, install a magnetic contactor on the inverters input side to configure
a circuit so that a current is shut off in case of fault.
● Do not remove a jumper across terminal P/+ and P1 except when connecting a DC reactor.
NOTE Set "1" in Pr. 0 "Brake mode selection" of the FR-BU2 to use GRZG type discharging resistor.
