11.3 FR-BU2-(H) Brake unit
POINT
Use a 200V class brake unit and a resistor unit with a 200V class servo
amplifier, and a 400V class brake unit and a resistor unit with a 400V class
servo amplifier. Combination of different voltage class units and servo
amplifier cannot be used.
Install a brake unit and a resistor unit on a flat surface vertically. When the
unit is installed horizontally or diagonally, the heat dissipation effect
diminishes.
Temperature of the resistor unit case rises to higher than 100 . Keep cables
and flammable materials away from the case.
Ambient temperature condition of the brake unit is between 10 (14 ) and
50 (122 ). Note that the condition is different from the ambient
temperature condition of the servo amplifier (between 0
(32 ) and 55
(131
)).
Configure the circuit to shut down the power-supply with the alarm output of
the brake unit and resistor unit under abnormal condition.
Use the brake unit with a combination indicated in section 11.3.1.
For executing a continuous regenerative operation, use FR-RC-(H) power
regeneration converter or FR-CV-(H) power regeneration common 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 the parameter No.PA02 of the servo amplifier to "
01".
When using the brake unit, always refer to the FR-BU2-(H) Brake Unit Instruction Manual.
