Product Description:
The 3NC157.60-1 is a motion and I/O controller produced by B&R Automation for the System 2005 Controllers series. Installed in multi-axis machinery, it coordinates positioning tasks, manages local I/O, and links the machine segment to a higher-level PLC through its integrated CAN servo interface. In this role, it serves as the real-time node that sequences drives, evaluates triggers, and exchanges bus data across the factory network.
The firmware divides program execution into cycle increments of 400 µs, allowing deterministic updates of interpolation and I/O images. When eight servo channels are configured, overall loop completion is guaranteed within 5.6 ms; this fixed limit prevents command overlap during synchronized moves. Mechanical groups with up to 8 axes can be attached, and each axis shares the same deterministic timeline. Field communication reaches a peak speed of 500 kbit/s, so parameter blocks and status words travel quickly between the controller and drive amplifiers. Cable runs may extend to 60 m before a repeater is required to maintain signal integrity, accommodating typical cabinet-to-machine distances in compact cells.
Volatile storage is provided by 2 MB of DRAM for variables and buffers, while firmware and user code reside in a nonvolatile 2 MB FlashPROM segment that retains data through power cycles. The electronics draw a maximum of 6 W, simplifying thermal management inside sealed panels. Two trigger inputs accept sinking signals at 24 VDC and can initiate time-critical captures without CPU latency. Bus isolation separates the CAN segment from the internal logic, helping protect controller operation from electrical disturbances on the communication line. External termination resistors allow the unit to be positioned anywhere along the trunk while maintaining proper bus termination. Node addresses are selected with a rotary switch, allowing the controller’s network address to be set directly at the unit without software configuration.
