Product Description:

The CLC-V02.1C-FW motion control card is produced by Bosch Rexroth Indramat and belongs to the CLC Motion Controllers series. This VME-bus module serves as the central processing element in multi-axis drive systems, executing application code that coordinates positioning, speed, and machine sequencing in automated equipment. By hosting user programs and exchanging data with servo drives over the backplane, it provides deterministic motion profiles for packaging, printing, and material-handling stations. This arrangement allows one controller to manage coordinated axis behavior from a single rack location.

The controller occupies a VME 6U card outline measuring 9.2 × 6.3 inches, so it fills two contiguous slots in a standard chassis. A Motorola 68020 processor clocks at 25.0 MHz, while a separate 68882 math coprocessor accelerates floating-point calculations for kinematic transforms. Nonvolatile program storage is provided by 1 Mbyte of flash EPROM, and dynamic parameters are retained in 32 Kbyte of battery-backed SRAM. During operation, the board draws +5 V 3.0 A; +12 V 100 mA; -12 V 70 mA, so rack power capacity must match the module load. The board runs under the pSOS real-time kernel, and a front-panel RS-232 port supports downloading and diagnostics without removing the module.

High-speed data exchange with other VME modules is enabled by 2 Mbyte of shared static RAM, which appears on the bus through A32, A24, A16 addressing modes. The controller supports four arbitration levels, allowing it to request bus access in an orderly way when multiple masters are present. Read and write transfers are matched to peripheral requirements through D8, D16, D32 data cycles, and eight mailbox interrupts provide asynchronous messaging to host CPUs. Local buffering of position tables helps the card maintain steady communication with connected motion axes while higher-level tasks run elsewhere in the rack.
