Function and Working Principle
The SK-R9-PINT1-FF6K acts as a high-reliability internal interconnect element inside the drive.
Its main functions include:
- Providing electrical connection between power modules and DC bus structure
- Ensuring stable high-current transfer paths
- Supporting modular assembly of PowerFlex 750 drive stacks
- Maintaining mechanical alignment between internal power components
- Reducing risk of loose connection, arcing, or thermal stress
System Role
Inside the drive:
AC Input → Rectifier → DC Bus → Power Connector (SK-R9-PINT1-FF6K) → Inverter Module → Motor Output
This component ensures continuity of the high-power internal circuit path.
Role in Industrial Control Systems
The SK-R9-PINT1-FF6K functions as:
- A power distribution interface inside VFD systems
- A critical interconnect for modular drive architecture
- A high-current conduction path component
- A mechanical/electrical alignment structure
It does not perform control logic—it is strictly part of the power hardware layer.
Industrial Applications
This component is used within:
- PowerFlex 750 high-power drive systems
- Conveyor drive systems
- Large pumping stations
- HVAC and chiller systems
- Industrial compressors
- Process industry motor control systems
- Heavy-duty automation machinery
It is always installed inside a complete drive assembly, not used externally.
Installation and System Integration
- Installed inside PowerFlex 750 drive enclosure
- Connects internal power modules and DC bus structure
- Requires correct frame-size matching (FF6 configuration)
- Installed during drive assembly or service replacement
- No external wiring required
- Must be handled with anti-static and high-voltage safety procedures
⚠️ Installation must be performed by qualified personnel due to high-energy DC bus risk.
Compatible System Components
- PowerFlex 750-Series AC Drives
- Frame 6 power modules
- DC bus capacitor assemblies
- Rectifier and inverter stacks
- SK-R9-PINT series interface kits
- Control and power interface boards
