1. Model structure and core parameters
1. Basic series: ERN1387
Type: Incremental encoder, which measures position, speed and direction by outputting pulse signals.
Application scenarios: CNC machine tools, servo systems, automated production lines and other high-precision control scenarios.
2. Resolution and signal parameters: -2048
Number of lines/pulses: 2048, that is, the encoder outputs 2048 signal cycles (sine wave or square wave) per revolution. After controller subdivision, higher accuracy (such as nanometer resolution) can be achieved.
3. ID number: 749144-01
Prefix 749144:
Indicates that this model belongs to the high-end incremental encoder product line of Heidenhain, which usually has better protection level, signal stability and environmental adaptability.
Compared with the mid- and low-end series (such as models with ID starting with 727), higher performance materials or processes (such as full metal housing, anti-corrosion coating) may be used.
Suffix 01:
Customized configuration logo, which may involve the following parameters (need to be confirmed in conjunction with official information):
Signal type:
Commonly used is RS422 differential digital signal (A/B/Z phase), which is compatible with controllers that support digital input (such as Siemens and Fanuc servo systems), has strong anti-interference ability, and is suitable for long-distance transmission.
Shaft type: cylindrical shaft (non-tapered), usually with a diameter of 9.525mm (compatible with general servo motor shafts), no taper locking device is required, and installation is convenient.
Cable/connector: Standard M23 connector or cable of a specific length (such as 5 meters), in line with industrial standard interfaces, compatible with most automation equipment.
Protection level: IP64 (splash and dust proof), some high-end models may be upgraded to IP67.
