FAQ What is the resolution of the HEIDENHAIN ROQ 425 326 171-01?This encoder has a single-turn resolution of 13 bits (8192 steps per revolution) and a multi-turn resolution of 12 bits (tracking up to 4096 revolutions). What is the difference between the SSI interface on this encoder and an EnDat interface?SSI (Synchronous Serial Interface) is a unidirectional digital interface for sending absolute position data. EnDat is a bidirectional HEIDENHAIN interface that can transmit position values, read and write parameters, and perform diagnostic functions, offering more advanced capabilities. How can I verify the functionality of this encoder before installation?Functionality can be verified using a compatible PLC, controller, or a dedicated encoder tester that supports the SSI protocol. By rotating the shaft and monitoring the output data stream, you can confirm it is providing correct and consistent position values. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
