14.3 Brake Unit
POINT
The brake unit and resistor unit of other than 200V class are not applicable to
the servo amplifier.
The brake unit and resistor unit of the same capacity must be combined.
The units of different capacities may result in damage.
The brake unit and resistor unit must be installed on a vertical surface in the
vertical direction. If they are installed in the horizontal direction or on a
horizontal surface, a heat dissipation effect reduces.
The temperature of the resistor unit casing rises to higher than 100°C. Do not
cause cables and combustibles to make contact with the casing.
The brake unit is the integration of the regenerative control and resistor and is connected to the bus (across
P-N) of the servo amplifier. As compared to the MR-RB regenerative option, the brake unit can return larger
power. Hence, use this brake unit when the MR-RB cannot provide sufficient regenerative capability.
When using the brake unit, set " 01" in parameter No.PA02.
