Maintain CNC Precision with the ENC-0008 Fadal Style Resolver Assembly

 

Introduction

In CNC machining, precision is everything. Even the smallest positioning error can affect part quality, repeatability, and overall productivity. That’s why feedback devices like resolvers play a critical role in your Fadal CNC machine.

The ENC-0008 Fadal Style Resolver Assembly is designed to deliver accurate position feedback for Glentek motors used in Fadal machines. Built for reliability and performance, this resolver helps ensure your machine maintains tight tolerances and smooth motion control.

In this blog, we’ll explore what the ENC-0008 does, why it matters, its compatibility, testing basics, and how it helps keep your Fadal CNC running at peak performance.

What Is the ENC-0008 Resolver Assembly?

The ENC-0008 is a Fadal-style resolver assembly used as a position feedback device in Fadal CNC machines. Its primary job is to convert the mechanical position of a motor shaft into electrical signals that the CNC controller can interpret.

This continuous feedback allows the controller to:

  • Monitor exact motor position

  • Correct movement in real time

  • Maintain machining accuracy

  • Ensure smooth and stable operation

Without reliable resolver feedback, your machine can experience positioning errors, poor surface finishes, and inconsistent results.

Why Resolver Feedback Is So Important

Resolvers are a key part of the CNC feedback loop. They tell the control where the axis actually is versus where it should be.

Key Benefits

1. High Precision
Accurate position data allows the machine to execute movements exactly as programmed.

2. Better Reliability
Resolvers are known for durability in harsh industrial environments.

3. Consistent Part Quality
Stable feedback helps maintain repeatability across production runs.

4. Reduced Scrap & Rework
Precise motion control minimizes costly mistakes.

For operations like milling, drilling, and cutting, this level of accuracy is essential.

Compatible Glentek Motors

The ENC-0008 resolver assembly is compatible with the following Glentek motors:

  • MTR-0002

  • MTR-0003

  • MTR-0010

  • MTR-0125

If you’re unsure about compatibility, confirming before purchase is always recommended to avoid downtime.

Resolver Testing Basics

Proper testing helps determine whether a resolver is functioning correctly or needs replacement.

Step 1: Resistance Check

AMCI Resolver Values

  • Pair A: 35–45 Ohms

  • Pair B: 125–135 Ohms

  • Pair C: 125–135 Ohms

Harowe Resolver Values

  • Pair A: 70–80 Ohms

  • Pair B: 190–220 Ohms

  • Pair C: 190–220 Ohms

(Pair B and C should match.)

Step 2: Coil-to-Coil Shorts

Measure other pin combinations outside the main pairs. These should show an open circuit.

Step 3: Shorts to Ground

Check resistance from each pin to the resolver frame. There should be no continuity.

Step 4: Voltage Check (Connected)

  • Pair A: ~1.7 VDC

  • Pair B & C: ~3.5 VDC

  • Pair A connects to the 1010 axis card via J2.

These checks help verify resolver health and prevent unnecessary part replacement.

Warranty Coverage

When purchased from ITSCNC, the ENC-0008 comes with a 90-day warranty covering manufacturing or operational defects. This provides added peace of mind and protection for your investment.

Why Choose Quality Replacement Parts?

Using OEM-quality or trusted replacement components ensures:

  • Proper fit and function

  • Long service life

  • Stable machine performance

  • Reduced unexpected downtime

High-quality feedback components like the ENC-0008 help maintain the overall health of your CNC system.

Availability & Support

Having access to in-stock critical parts reduces costly machine downtime. Reliable suppliers maintain inventory so you can get replacement parts quickly when needed.

Support from knowledgeable CNC specialists also helps with:

  • Compatibility checks

  • Installation guidance

  • Troubleshooting

  • Correct part selection

Conclusion

The ENC-0008 Fadal Style Resolver Assembly is a small but vital component that plays a big role in CNC accuracy and reliability. By providing precise position feedback for Glentek motors, it helps your Fadal machine maintain performance, consistency, and productivity.

If your machine is showing signs of positioning errors or feedback issues, checking or replacing the resolver can make a significant difference.

Keeping your feedback system in top shape means keeping your CNC operation running smoothly and profitably.
