Information About 25-ENC-1

The 25-ENC-1 is part of the PowerFlex 525 accessory family from Allen-Bradley, developed to enable advanced motor control functionality. This quadrature incremental encoder input card supports both single-ended and differential wiring configurations, accepting 5, 12, or 24V signals. It sources 5 or 12VDC power and can be internally powered from the drive or supplied externally, drawing 250 mA at 12V nominal. The module integrates with the PowerFlex 525 drive to support closed loop velocity vector control, enabling not only speed regulation but also positioning capabilities for higher precision applications. Designed with DIP switch voltage selection, proper torque specifications for wiring, and a wide wire size range, it ensures secure installation and dependable performance in automation environments.

Key Features:

  • Design: Quadrature incremental encoder input module with robust industrial build.
  • Compatibility: Fully supported by Allen-Bradley PowerFlex 525 adjustable frequency AC drives.
  • Voltage Support: Accepts 5V, 12V, or 24V signals in single-ended or differential input wiring.
  • Power Options: Sources 5 or 12V power and can be internally powered by the drive or externally supplied.
  • Control Function: Enables closed loop PM control through velocity vector method, supporting precise speed and positioning control.
  • Configuration: Supports encoder resolution up to 1024 pulses per revolution (PPR) for accurate feedback.
  • Installation: Built-in DIP switch for voltage source selection and screw terminals rated for 0.08–2.08 mm² wiring.
  • Reliability: Secure terminal tightening with 0.18–0.22 Nm torque ensures stable connections.

The 25-ENC-1 delivers the reliability and precision required for advanced motor control and feedback integration with PowerFlex 525 drives.

Frequently Asked Questions about 25-ENC-1
Question: What is the maximum supported encoder resolution (PPR) for the 25-ENC-1?
Date Update:27/05/2025
Answer:

The 25-ENC-1 supports encoder resolutions up to 1024 pulses per revolution (PPR). This resolution is adequate for most closed-loop control applications requiring moderate position accuracy. It ensures smooth motor operation with real-time feedback. For applications demanding higher resolutions, alternative modules may be considered.

Question: How is the encoder powered—internally or externally?
Date Update:27/05/2025
Answer:

The encoder can be powered either internally from the PowerFlex 525 drive or externally from an independent power source. Internal power is selectable between 5V and 12V via a DIP switch. If a 24V encoder is used, external power is required. Always match voltage levels with the encoder’s specifications.

Question: Can the 25-ENC-1 be used with PowerFlex 523 or 527 drives?
Date Update:27/05/2025
Answer:

No, the 25-ENC-1 is specifically designed for use with PowerFlex 525 drives. It is not compatible with PowerFlex 523 or 527 models due to differences in hardware and control methods. Using it with unsupported models may lead to malfunction. Always verify compatibility with official documentation.

Question: What wire sizes are compatible with the 25-ENC-1 terminals?
Date Update:27/05/2025
Answer:

The terminals accept wire sizes ranging from 0.08 mm² (28 AWG) to 2.08 mm² (14 AWG). Use wire sizes appropriate for current and signal strength. Thicker wires ensure lower voltage drop. Stranded wires are generally easier to route and connect.

Question: Is the 25-ENC-1 still being manufactured?
Date Update:27/05/2025
Answer:

Yes, according to Rockwell Automation, the 25-ENC-1 is currently in "Active" lifecycle status, indicating it is still being manufactured and supported. You can verify this status on the official Rockwell Automation website.
