Product Description:

The CLC-P01.1A-FW is a motion controller module manufactured by Bosch Rexroth Indramat and delivered within the CLC Motion Controllers series. It executes user-written programs that synchronize multiple servo drives through a dedicated Sercos ring, providing deterministic axis coordination for packaging, metal-forming, and automated assembly machines. By centralizing motion logic, it reduces PLC scan time and enables tighter path following than stand-alone drive algorithms. This arrangement lets the controller manage coordinated motion profiles and synchronized axis responses from a single control point.

The board uses a 68EC020 CPU operating at 25.0 MHz as its computational core. This 32-bit architecture handles logical sequencing, while a 68882 coprocessor performs rapid trigonometric and floating-point calculations needed for camming and interpolation. Two EPROM sockets provide a maximum code space of 1 Mbyte, and the onboard 512 Kbyte SRAM stores variables, task stacks, and 512 general-purpose registers used during operation. The controller maintains 256 global integer variables and 256 global floating-point variables that can be addressed by IEC-1131 function blocks. An isolated Sercos channel supplies one input telegram and one output telegram per cycle, so axis status and command words move without software overhead. Typical consumption is 20 mA from the +12 V rail, with most logic power drawn from +5 V.

High-speed data sharing with companion PLCs is supported by a 4096 bytes dual-port RAM block, allowing asynchronous reads while the motion kernel runs uninterrupted. The +5 V plane demands up to 800 mA, so cabinet supplies must account for startup inrush. Program loading and diagnostics are available through a RS-232 or RS-485/422 serial port, and the real-time clock retains data with a CR2477N (MnO2/Li) lithium cell. Mechanical addressing switches, along with dedicated Sercos input and output connections, complete the front panel and keep service access on the module face.
