Full Application Cases of HEIDENHAIN 1065932-68 (ECN413 2048 EnDat01)

This model is an absolute encoder with integrated bearings, featuring a φ12 mm through hollow shaft and 1 m bare wire output. It adopts EnDat01 protocol, delivers 2048-line 1 Vpp sine/cosine signals and 13-bit single-turn absolute position data, with IP64 protection and wide temperature & high shock resistance. Six major mainstream application fields are listed below, including matched equipment, process benefits and on-site operating conditions.

1. Machine-Room-Less Permanent Magnet Synchronous Elevator Traction Machines (Largest-Volume Core Application)

Caso 1: Gearless Traction Machine Retrofit for Thyssenkrupp / Kone Domestic Elevators

1. Matched Equipment: MRL permanent magnet synchronous traction machines for 4–10 storey residential machine-room-less elevators & villa lift main drives
2. Matching Advantages

Retains absolute rotor position after power failure; no homing required upon power-up for fast, precise car leveling

2048-line sinusoidal signals enable stable low-speed start/stop with 0.01 mm positioning accuracy, eliminating elevator shaking, overtravel and under-travel faults

-40~+100℃ wide temperature range adapts to seasonal temperature fluctuations, heavy dust and humid shaft environments; IP64 sealing blocks concrete dust and condensate inside elevator hoistways

3. Exclusive Advantages of Model 1065932-68: Dual axial/radial 1 m bare wire outlet fits compact rear mounting space of traction machines; no transition connectors required to reduce potential failure points. The φ12 mm clamping hollow shaft sleeves directly onto the motor spindle for space-saving installation.
4. On-Site Performance: After replacing domestic imitation encoders, elevator leveling error drops from ±5 mm to ±0.5 mm; overspeed protection response time <9 μs, with annual inspection failure rate reduced by 70%.

Caso 2: Main Drive Feedback for Commercial Heavy Passenger & Freight Elevators

Applied to high-rise 800–1600 kg freight elevators, paired with Monarch / STEP EnDat-protocol dedicated elevator inverters for speed closed-loop control, rotor commutation and overspeed monitoring on safety circuits.

1. Spindle & Feed Servo Motors for CNC Machine Tools

Caso 1: High-Speed Spindle Servos for Vertical Machining Centers (Legacy Siemens 802D / 840D Systems)

1. Equipo: Domestic VMC850 vertical machining centers, second-hand DMG lathes, permanent magnet synchronous spindle servo motors
2. Compatibility Rationale: EnDat01 compatible with early Siemens CNC drives; 1 Vpp sinusoidal signals maintain stable high-speed operation up to 12,000 rpm without subdivision loss. Integrated bearings withstand cutting vibration up to 300 m/s², delivering long-term stable operation in workshops with oil contamination and metal dust.
3. Process Benefits: Spindle indexing accuracy ±1 arcsecond with no visible tool joint lines in mold milling and boring. Absolute angle readout on power restart eliminates spindle homing steps, cutting single-piece machining cycle time by 15%.

Caso 2: Feed Axis Servos for CNC Cylindrical Grinding Machines

X/Z axis servos on precision crankshaft & bearing grinders rely on high-resolution sinusoidal feedback to guarantee micron-level dimensional consistency of ground workpieces. Wide temperature tolerance suits workshop environments splashed with grinding coolant.

Key Selection Differentiators of 1065932-68 (Series Suffix Comparison)

On-Site Usage Restrictions for This Model (Applicable to All Cases)

1. Do not apply excessive clamping torque to the hollow shaft, as it will compress and damage the grating disk.
2. Bare-wire variant (-68) is not recommended for drag chain moving applications; its fixed cable design is only suitable for stationary wiring.
3. Drives must support EnDat01. EnDat2.2-capable drives offer backward compatibility but require parameter tuning for protocol matching.
4. An additional protective sleeve is recommended for machine tool environments with heavy coolant splashing and water mist.
