ENC-0008R FADAL REMANUFACTURED RESOLVER

Technical Reference: The Fadal ENC-0008 Resolver Assembly

Think of your Fadal servo system as a precision feedback loop; if the CPU is the brain, the ENC-0008 Resolver Assembly is the high-fidelity sensor that continuously reports the rotor’s angular position. At CNCPros International, we have spent nearly three decades mastering the intricacies of Fadal feedback systems. When it comes to the ENC-0008, we don't just sell components—we provide the technical authority required to keep your axis motion within sub-micron tolerances.

The ENC-0008 is a specialized, brushless rotary transformer designed to operate in the high-electromagnetic-interference (EMI) environment of a CNC motor housing. Unlike standard encoders, which can be susceptible to electrical noise and heat, the resolver’s rugged electromagnetic design makes it the superior choice for mission-critical positioning.

Technical Functionality: The Feedback Loop

The resolver functions as an analog transducer. It is energized by an excitation signal from the 1010-series Axis Controller, and its output is a pair of sine/cosine signals that represent the rotor's exact angular position.

• Continuous Position Data: Because it is an analog device, the ENC-0008 provides infinite resolution, allowing the axis controller to track the motor shaft's position at all times, even at standstill.
• Glentek Integration: The ENC-0008 is the specific feedback device for the Glentek motor series (MTR-0002, MTR-0003, MTR-0010, MTR-0125). It allows the 1010-series Axis Card to close the loop on velocity and position, which is essential for Fadal’s signature rapid moves and rigid tapping cycle
• Harsh Environment Durability: Built to withstand vibration, heat, and oil mist, the ENC-0008 is the robust backbone of the Fadal servo system.

Diagnostic Authority: The CNCPros Resolver Testing Protocol

A "Servo Fault" does not always mean a bad motor. Before replacing your resolver, use our field-proven diagnostic steps to isolate the fault.

Required Tool: High-impedance Digital Multimeter (DMM).

Step 1: Resistance Mapping (The Coil Signature)

Measure the resistance across the pairs at the interface connector. If your readings deviate from these specifications, the internal windings have likely suffered thermal damage.

Step 2: Insulation and Short Testing

• Coil-to-Coil: Measure resistance between any pins not belonging to the same pair. Any reading other than "Open Circuit" (OL) indicates an internal short.
• Short to Ground: Measure resistance from each pin to the resolver’s metal housing. Any continuity to the frame is a catastrophic failure that can damage your 1010-axis card.

Step 3: Operational Voltage Check

With the resolver connected and the axis powered (in a steady state), measure the operating voltages:

• Pair A: 1.7 VDC
• Pair B & C: 3.5 VDC

The CNCPros International Advantage

We are not just a parts supplier; we are the technical partner that keeps your machines in the cut.

• Compatibility Verified: Our ENC-0008 units are verified to perfectly match the timing and impedance requirements of all compatible Glentek motors.
• The Authority on Fadal: With over 28 years of experience, our technicians can walk you through the diagnostic process to ensure you aren't replacing a perfectly good resolver when the actual issue is a faulty cable or a loose connection at the 1010-series J2 connector.
• Ready-to-Ship Inventory: We maintain a deep stock of ENC-0008 units to ensure that when your axis faults out, you are back in production in the shortest time possible.

Is your axis throwing erratic "Servo Faults" or exhibiting positioning drift?
