Product Description:

The CLC-P02.2B-FW is a plug-in motion controller produced by Bosch Rexroth Indramat for the CLC Motion Controllers series. Installed in a drive rack, it interprets position commands and generates setpoint data so multiple servo axes stay synchronized during machining, packaging, or material-handling sequences. By embedding the motion kernel on the card, it keeps high-speed interpolation and path planning close to the drives, reducing fieldbus latency and simplifying cabinet layouts. This arrangement helps the rack respond quickly to coordinated moves such as contouring, indexing, and synchronized transfer operations.

Central processing is handled by a 68EC020 microprocessor that operates at a clock frequency of 25.0 MHz, giving the controller deterministic cycle times for real-time trajectory calculations. Volatile storage is provided by 512 Kbyte of SRAM, and this memory is backed up by the +5 V logic rail that draws 800 mA. The available SRAM is used for temporary tables, motion states, and intermediate values generated during active control loops. Two onboard serial ports allow local diagnostics, and the default asynchronous link starts at 9600 baud so a standard terminal can be connected without changing the link parameters. One serial connector can also be used for a teach pendant, and the serial links support parameter review and status monitoring through a direct connection.

A dedicated 68882 math coprocessor accelerates trigonometric and floating-point routines, freeing the main CPU for sequencing tasks and improving contour accuracy. The separate coprocessor is useful for circular interpolation, coordinate transforms, and other math-intensive motion routines. Program and parameter images reside in an EPROM bank rated at 1 Mbyte, and two unpopulated sockets allow additional nonvolatile storage for application data. Fiber-optic motion commands move through the SERCOS interface, which is presented as 1 In, 1 Out to form a ring with adjacent drives. The optical ring passes command data between neighboring drives while preserving closed-loop timing across the axis group. Control electronics powered by the auxiliary rail draw only 20 mA at +12 V, keeping cabinet heat minimal.
