HEIDENHAIN ERN1387.035-2048 749147-01 ERN 1387 series

1. Basic series: ERN1387

Type: Incremental Encoder, high-precision position and speed measurement through sine wave signal output.

Application positioning: CNC machine tools, precision servo systems, automated production lines and other scenarios with extremely high feedback accuracy requirements.

2. Key parameters: 035-2048

035:

Represents the shaft type is a tapered shaft (1:10 taper), the shaft diameter is usually 9.525mm (adapted to the taper interface of Siemens and other brands of servo motors), and needs to be installed with a special locking nut, suitable for high torque or frequent start-stop conditions.

2048:

Number of lines/number of pulses: 2048 sine wave signal cycles (1Vpp analog signal) are output per revolution, and nanometer resolution can be achieved through an external subdivision module (such as the Heidenhain IBV series) (for example, after subdividing 1000 times, the number of pulses per revolution reaches 2048000).

3. ID number: 749147-01

Prefix 749147:

It belongs to the high-end incremental encoder product line of Heidenhain, and its features are:

All-metal housing, protection level is usually IP64/IP65 (dust and splash proof), suitable for harsh industrial environment;

Using high-precision grating scale and temperature compensation technology, the signal stability is better than the economical series (such as models with ID starting with 727).

Suffix 01:

Customized configuration identification, which may include the following information (need to be confirmed in conjunction with the official manual):

Signal type: analog sine wave signal (1Vpp), which needs to be converted into digital signal by subdivision module before connecting to the controller;

Connector type: standard M23 connector or specific length cable (such as 5 meters), compatible with industrial standard interface;

Mechanical options: tapered shaft with keyway to enhance the torsional strength of mechanical connection.
