Tips: The factors that affect the encoder reproducibility
- Noise: The connection between encoder and PLC or electronic driver does not conform to the standard EMC guidelines (for example, a more practical method is to provide proper shielding for both ends of encoder connection). This connection is susceptible to noise or causes problems associated with electromagnetic interference.
- Installation: The encoder is not installed on the motor for proper mechanical installation (eg poor connection will result in frequency hopping of the encoder).
Therefore, extreme care must be taken when installing a machine encoder or an encoder with an induction motor system to ensure that the encoder is mounted on the machine by suitable mechanical means and that the connection of the electric drive or PLC complies with the EMC requirements.
