Product Description:
The CLC-D 1.1A-GPS-01.RS is a motion controller produced by Bosch Rexroth Indramat within the CLC Motion Controllers series. As the central processor in a multi-axis drive system, it interprets program instructions, exchanges position data over SERCOS fiber links, and issues deterministic command words to downstream drives. One SERCOS input port and one output port give the unit a direct pass-through path for ring topologies, while two EPROM sockets allow control software or application code to be stored locally for standalone execution in factory automation cells.
The controller is built around a Motorola 68EC020 CPU that runs at 25.0 MHz, providing adequate cycle time for coordinated motion tasks and basic PLC logic. All logic operates from a regulated supply of +5 Vdc, so the system requires a clean backplane rail at that level. Program code resides in an EPROM array sized at 1 Mbyte, while variable data and dynamic buffers are kept in 512 Kbyte of battery-backed SRAM. Communication with external diagnostics or HMI terminals occurs through 2 serial ports that use the 8N1 format, and the Bb Contact digital I/O point can report a general fault condition to higher-level safety relays. No connection is provided on the mezzanine bus edge, leaving that space open for future options.
A lithium CR2477N cell rated at 0.9 Ah maintains the SRAM image when mains power is removed, and the board’s steady-state draw of 800 mA must be included in the cabinet’s 5 V power budget. Numeric processing for gearing ratios and interpolation is accelerated by the dedicated 68882 math coprocessor, which frees the main CPU for I/O handling. The single Bb Contact, together with the matched SERCOS ports, gives the controller a minimal discrete interface that keeps external wiring simple in retrofit and new machine installations.
