Mark or photograph the encoder position before any bearing work, and send the encoder with the motor if the motor has been opened.<\/p>\n<p>Read more: <a href=\"\/heidenhain-encoder-reprogramming\/\">Heidenhain encoder reprogramming, alignment and refurbishment<\/a>.<\/p>\n<h3>Frequently asked questions<\/h3>\n<p><strong>My motor stopped working after the bearing was replaced. Why?<\/strong><br \/>Replacing a bearing separates the rotor and encoder, so the encoder loses its position reference. The motor then gives an encoder or commutation error and needs encoder alignment and reprogramming.<\/p>\n<p><strong>What do you use to reprogram the encoder?<\/strong><br \/>Star uses its universal programming kit to program and align the encoder for the motor it will run on.<\/p>\n<p><strong>Do you reprogram Heidenhain EQI 1331 encoders?<\/strong><br \/>Yes. Star Automations reprograms and aligns this encoder series for servo motors, and can supply a refurbished unit.<\/p>\n<p><strong>Replacement encoder fitted but the drive still rejects it. Why?<\/strong><br \/>A new or used encoder must be programmed for the motor and drive. Fitting alone is not enough.<\/p>\n<p><strong>Can you refurbish my encoder instead of buying new?<\/strong><br \/>Yes. Send the encoder label and the fault, and we confirm whether it can be repaired, reprogrammed or replaced with a refurbished unit.<\/p>\n<p><strong>Which motors use this encoder?<\/strong><br \/>The same Heidenhain encoder family is fitted to many servo motors. Send the encoder label and the motor nameplate and we confirm compatibility.<\/p>\n<p><strong>What should I send for a quote?<\/strong><br \/>A clear photo of the Heidenhain label, the motor nameplate, the drive make and the fault, on WhatsApp +91 97866 22233.<\/p>\n<p><strong>Where can I get this in India?<\/strong><br \/>Star Automations, Puducherry, with GST invoice and delivery across India.
