11.3 FR-BU2-(H) brake unit
POINT
Use a 200 V class brake unit and a resistor unit with a 200 V class servo
amplifier, and a 400 V class brake unit and a resistor unit with a 400 V class
servo amplifier. Combination of different voltage class units cannot be used.
When a brake unit and a resistor unit are installed horizontally or diagonally, the
heat dissipation effect diminishes. Install them on a flat surface vertically.
The temperature of the resistor unit case will be higher than the ambient
temperature by 100 ˚C or over. Keep cables and flammable materials away from
the case.
Ambient temperature condition of the brake unit is between -10 ˚C and 50 ˚C.
Note that the condition is different from the ambient temperature condition of the
servo amplifier (between 0 ˚C and 55 ˚C).
Configure the circuit to shut down the power-supply with the alarm output of the
brake unit and the resistor unit under abnormal condition.
Use the brake unit with a combination indicated in section 11.3.1.
To perform continuous regenerative operation, use the FR-RC-(H) power
regeneration converter, FR-CV-(H) power regeneration common converter, or
FR-XC-(H) multifunction regeneration converter.
Brake unit and regenerative options (Regenerative resistor) cannot be used
simultaneously.
Connect the brake unit to the bus of the servo amplifier. As compared to the MR-RB regenerative option, the
brake unit can return larger power. Use the brake unit when the regenerative option cannot provide sufficient
regenerative capability.
When using the brake unit, set [Pr. PA02] to "_ _ 0 1".
When using the brake unit, always refer to the FR-BU2 Instruction Manual.
