HEIDENHAIN ERN 1387-2048 ID 749147-02 ERN 1387 series

Based on the information of HEIDENHAIN ERN 1387-2048 ID: 749147-02, combined with the naming rules and public information of HEIDENHAIN encoders, the following is a detailed analysis:

I. Model structure and parameter interpretation

1. Basic series: ERN 1387

Type: Incremental Encoder, used to measure rotational position, speed and direction.

Application areas: industrial automation, CNC machine tools, servo motor systems and other high-precision control scenarios.

2. Resolution: -2048

Number of lines/pulses: 2048 lines, that is, 2048 pulses (or sine wave signal cycles) are output per revolution.

Subdivision accuracy: After subdivision with the controller, higher resolution can be achieved (for example, 1Vpp signal can reach nanometer accuracy through the subdivision card).

3. ID number: 749147-02

Prefix 749147: indicates that this model belongs to the mid-to-high-end incremental encoder product line of Heidenhain, and may correspond to the tapered shaft design (adapting to specific motor interfaces).

Suffix -02: customized parameter identification, which may involve the following configurations (need to be confirmed in conjunction with official information):

Shaft type: 1:10 tapered shaft (diameter 9.25mm), commonly used in servo motors of brands such as Siemens.

Signal type:

It may be 1Vpp sine/cosine analog signal (typical output of the ERN1387 series), used in analog systems requiring high resolution.

Or RS422 differential digital signal (A/B/Z phase), adapted to controllers that support digital inputs.

Protection level: IP64 or higher (need to check the product manual).

Cable/connector: Cable of specific length or connector type (such as Heidenhain standard plug or customized interface).
