| Input Voltage | Likely 380-480V AC (Three-Phase) |
| Power Rating | Unknown (The ’45’ may relate to a specific kW or HP rating) |
| Output Frequency | 0 to 400 Hz (Typical for VFDs) |
| Control Method | Volts per Hertz (V/Hz) or Sensorless Vector Control |
| Enclosure Type | IP20 (Open Style) or NEMA/UL Type 1 (Depending on full model) |
| Interface | Digital I/O, Analog I/O, RS-232/RS-485 Communication |
✨ Product Advantages (General to the 1391 Series at the time)
- Precision Motor Control: Offered improved speed and torque regulation compared to older analog drives.
- Digital Configuration: Easy setup and programming via a digital human-machine interface (HMI) or software.
- Integrated Protection: Included robust protection features for the motor and the drive itself (e.g., overcurrent, overvoltage, ground fault).
- Reliability: Built with Allen-Bradley’s standard for rugged industrial operation.
⚠️ Important Considerations (Notes for Use)
- Obsolescence: The 1391 series is obsolete. Spare parts and technical support from the manufacturer are extremely limited or unavailable.
- Replacement/Upgrade: For new installations, it is strongly recommended to use the current Allen-Bradley drive platforms, such as the PowerFlex family (e.g., PowerFlex 755 or 525 series), which offer modern features, networking, and support.
- Installation Environment: Drives must be installed in a clean, dry, and cool environment, respecting the specified clearances for ventilation.
- Wiring Practices: Use proper shielded motor cable and ensure correct grounding to meet EMC/EMI requirements and ensure safe operation.
- Parameter Backup: Always back up the drive’s configuration parameters before any maintenance or replacement.
🏭 Product Applications
The 1391 series drives were typically used in industrial settings that required reliable and variable speed control for motors, including:
- Conveyors and Material Handling Systems: Controlling acceleration and speed for smooth product movement.
- Pumps and Fans: Energy-saving applications where flow or pressure needs to be regulated.
- Machine Tools: Providing adjustable speed for spindles and feed axes.
- Mixers and Agitators: Controlling process speed for consistency.
