Overview
The Allen-Bradley 160-BA01NSF1 is a robust 3-phase variable speed motor drive from the Bulletin 160 Smart Speed Controller (SSC) series. Designed for compact installation and quiet operation, this analog signal follower controller delivers proportional motor speed control without preset speed limitations, making it suitable for applications requiring continuous and responsive speed modulation across legacy industrial systems.
Key Features
- Analog Signal Follower Mode: Continuous speed modulation via external potentiometer or 4-20 mA analog input (±10 VDC compatible)
- Compact Convection-Cooled Design: Space-saving form factor for motor or chassis mounting
- Programmable Stopping Modes: Ramp to Stop (0.1–600 s), Coast to Stop, DC Injection Braking (0–25 s)
- Flexible Output Control: Configurable output frequency (0–240 Hz) and voltage (0V to input voltage)
- Status Monitoring: Form C relay contact output for operating status feedback

Typical Applications
The 160-BA01NSF1 is commonly deployed in:
- Legacy machine tool variable speed control systems
- Conveyors and material handling equipment requiring proportional speed adjustment
- Pump and fan applications with continuous analog control
- Industrial mixers and agitators with modulated motor output
- Textile and packaging machinery requiring responsive speed modulation
Compatibility & Replacements
The 160-BA01NSF1 was discontinued by manufacturer in June 2010. For legacy system maintenance, this used unit serves as a direct replacement in existing 160 SSC installations. Modern alternative options include newer Allen-Bradley variable frequency drives (VFDs) from the PowerFlex or Micro800 series, though migration may require control rewiring. Consult with Rockwell Automation support for compatibility assessment with your specific application. This controller is not compatible with Studio 5000 Logix Designer—it operates as a standalone variable speed controller, not as a PLC processor.
