Brake unit selection

1. What is the difference between the brake units FR-BU and BU? Is it presence of fault output?
2. Power supply voltage 480 V
When using the inverter FR-A540-30K and brake unit FR-BU-H30K with commercial resistors:
- What resistance (Ω) and power (W) should I choose?
- What resistance value can be connected?
3. What are the resistor specifications (watts and Ω) of the FR-BR-H30K?
Category : 


1. The BU brake unit does not have the fault output.
Multiple BU brake units can be connected in parallel.
2. Power supply voltage 480 V
- What resistance value can be connected?
The specification value of the FR-BR-H30K resistor is 4800 W, 16.5 Ω.
Choose a resistor with the same specifications.
3. 4800 W, 16.5 Ω
