- Any industrial environment utilizing ABB IRC5-controlled robots
Working Principle: When the robot system powers down or experiences an emergency stop, residual energy remains stored in the drive system’s capacitors and motor windings. The bleeder resistor provides a controlled path for this energy to dissipate as heat, preventing dangerous voltage buildup that could damage electronic components. The resistor is sized and rated to handle the specific energy levels of ABB IRC5 systems, ensuring complete and safe discharge within specified timeframes.
Material Composition:
- High-grade resistive alloy elements
- Thermally optimized housing for heat dissipation
- Industrial-grade mounting hardware
- High-temperature resistant insulation materials
Installation Requirements:
- Install inside IRC5 controller cabinet in designated mounting location
- Ensure adequate clearance for heat dissipation (minimum 50mm from adjacent components)
- Connect to designated discharge circuit terminals
- Verify proper ventilation within cabinet enclosure
Usage Precautions:
- Resistor surface reaches high temperatures during operation—avoid contact during and after discharge cycles
- Ensure cabinet ventilation is maintained to prevent heat accumulation
- Inspect resistor condition regularly for signs of thermal degradation
- Replace immediately if resistance value deviates from specifications
- Do not bypass or remove bleeder resistor—this compromises system safety
- Allow adequate cooling time before maintenance activities
