HEIDENHAIN ERN rotary encoders have an integral bearing and a stator coupling. The shaft of the ERN is connected directly to the measured shaft. During angular acceleration of the shaft the stator coupling must absorb only that torque resulting from friction in the bearing. ERN rotary encoders therefore display a high dynamic performance and high natural frequencies.

Encoder Heidenhain ERN 1387 The encoder ERN 1387 is an incremental-type encoder. Incremental signals are sin-cos signals. Technical data Line counts 2048 Power supply 5 V ± 5% Current consumption (without load) ≤ 130 mA The encoder must be connected to the inverter according to the specification in Table 6. Cable shield must be connected to housing. The feeding of the sensor is connected inside to the main feeding.
