Product Description:
The CLC-D02.2M-FW motion controller is produced by Bosch Rexroth Indramat and belongs to the CLC Motion Controllers series. It performs trajectory calculations and axis interpolation for Diax servo amplifiers, allowing centralized logic to replace distributed drive intelligence in automated assembly lines. The board communicates with adjacent components over one SERCOS optical ring and a universal asynchronous serial link. This allows it to synchronize drive behavior with commands from a supervisory PLC. Because the controller handles coordinated motion at the rack level, multiple axes can follow shared paths and timing relationships without placing that burden on each individual amplifier.
Electrical power comes from a +5 Vdc backplane rail, which keeps the supply requirement simple and limits heat dissipation. Inside the controller, a 25.0 MHz system clock drives the Motorola 68EC020 CPU, and motion calculations are assisted by a separate coprocessor on the mezzanine. Volatile program variables reside in 512 Kbyte of SRAM. Two EPROM sockets store the operating code so the controller can start immediately after power is applied. Parameter uploads and diagnostics pass through the multi-protocol RS-232/422/485 port, which supports point-to-point wiring to service computers or gateway devices. A single SERCOS input and a single SERCOS output terminate the fiber ring, the mezzanine bus supports option cards, and one mezzanine slot is provided for local I/O expansion. Status codes are shown on an integrated seven-segment display.
The controller draws 800 mA from the backplane rail when all communication channels are active. Coordinated motion tasks are off-loaded to the 68882 coprocessor, freeing CPU bandwidth for ring management of up to 30 Diax03 Drives on the SERCOS loop. Runtime data such as drive position tables is maintained when control power is removed by a board-mounted lithium battery rated at 0.9 Ah. The cell is a CR2477N MnO₂/Li type mounted in a protected clip next to the mezzanine connector. Battery-backed memory helps preserve stored data through control power interruptions.
