B&R Industrial Automation 8BAC0122.000-1 Interface Module

8BAC0122.000-1 is an ACOPOSmulti plug-in module that provides a resolver interface for BR servo systems, enabling direct integration of resolvers into the ACOPOSmulti drive family with automatic identification by the ACOPOSmulti OS. It is designed to be installed in BR ACOPOSmulti modules, occupying slots 1 and 2, and connects to resolvers via a 9-pin DSUB encoder input, with encoder monitoring and UP/DN status LEDs for quick fault and travel indication. The resolver delivers absolute position over one revolution, and careful homing with a reference switch is required for longer motion paths since the resolver does not store parameters like an EnDat encoder. Electrical characteristics include a maximum power consumption of 1 W, an output voltage of typ. 3 V eff, and a maximum output current of 50 mA eff, with an encoder update rate up to 10 kHz and a recommended encoder cable length up to 100 m. Position resolution at ü = 0.5 is 22600 multiplied by the number of pole pairs, reflecting how the module scales with resolver geometry. The unit is packaged with safety and compliance in mind, carrying CE and UKCA certifications and UL/cULus listing, which supports use in a broad range of industrial environments. The ACOPOSmulti model data identifies the device as 8BAC0122.000-1 with a BR ID code of 0x20B6, reinforcing its role as a resolver interface within BR’s motion-control ecosystem. In practice, this module enables reliable resolver-based feedback for BR motors and external axes within ACOPOSmulti systems, delivering dependable, high-speed positional data crucial for precision motion control in automated manufacturing settings.
