The 8AC122.60-1 is a high‑performance resolver interface plug-in module designed to be installed directly in B&R ACOPOS servo drives, allowing the connection and monitoring of BRX series resolvers on servo axes. It generates a 10 kHz reference output with approximately 3.4 Veff differential reference voltage and up to 50 mAeff reference current, and accepts resolver feedback signals at 10 kHz input frequency with an input voltage range of 3–7 Vrms. The module offers 14-bit angular position resolution, a 2.5 kHz bandwidth and typical accuracy of ±8 angular minutes, delivering precise rotor position feedback suitable for demanding servo applications.
Signal transmission between the resolver and the ACOPOS drive is handled via differential signaling, supporting cable lengths up to 100 m when using appropriate shielded resolver cables. The module connects to the drive via a 9‑pin female DSUB connector and supports encoder monitoring and diagnostics, with front LED status indicators to display operating status and fault conditions. Maximum power consumption is around 2.5 W, and it is intended for use within the environmental limits of ACOPOS drives (typically 5–40 °C nominal, 55 °C max operating and 5–85% relative humidity).
Typical applications include position and speed control of synchronous and asynchronous servo motors in packaging, printing, machine tools and general automation, where resolvers are preferred for their robustness and high shock/vibration tolerance. By using the 8AC122.60-1, users can integrate resolver‑equipped motors into B&R ACOPOS servo systems while benefiting from accurate feedback and built‑in diagnostic capabilities.
