Encoder Incremental; Encoder Assembly - WEG ENC1 Serie Guía De Instalación, Configuración Y Operación

3. EnCoDER inCREMEnTaL

The signal specifications for the inputs of the encoder incremental of modules
ENC-01 and ENC-02, are effective for Dynapar encoder model HS35B. To use
another type of encoder check if the pins and signal sequence are equivalent to the
shown model.

3.1. Encoder assembly

It is important to follow some recommendations during assembly of the encoder
on the motor:
1) The encoder must be coupled directly to the shaft of the motor without torsional
flexibility;
2) Both the shaft and metal frame of the encoder must be electrically isolated
from the motor (minimum distance 3mm);
3) Flexible and high quality coupling must be used to avoid mechanic oscillation
or backlash.
Figures 5 and 6 show encoder assembly of self-ventilated and forced ventilated
motors.
