Product Description:
The CLC-D02.2A-FW is a motion controller manufactured by Bosch Rexroth Indramat for the CLC Motion Controllers series. It serves as the computing center that synchronizes multiple servo drives over the SERCOS ring in automated machinery, executing real-time axis calculations and diagnostic routines needed for coordinated motion. Its role is focused on control and data processing rather than direct power conversion, so it manages command flow, axis relationships, and system responses from a central location. This arrangement supports coordinated movement in machines that require several axes to start, stop, and interpolate together.
The controller is built around a 68EC020 central processor that runs at 25.0 MHz, and numeric processing for trajectory generation is accelerated by a dedicated 68882 math coprocessor. Volatile program variables are held in 512 Kbyte of SRAM, while user programs reside in a socketed EPROM bank that provides 1 Mbyte of nonvolatile storage across two devices. This combination gives the board separate resources for general control tasks and floating-point calculations. Two serial ports support basic HMI communication or service access, and a SERCOS input together with a SERCOS output forms the optical ring interface. A CR2477N lithium manganese-dioxide cell supports power-fail data retention, which helps preserve stored information when rack power is removed.
The control board operates from a backplane supply of 5 Vdc and draws up to 800 mA during full computation and communication load. It supervises as many as 8 SERCOS-linked drives while keeping configuration codes and axis status in battery-backed SRAM, so important motion data can remain available after a power interruption. A front-panel 7-Segment LED provides immediate hexadecimal error reporting for local status review. The combination of optical ring communication and serial channels allows the controller to exchange motion data, status information, and setup messages with the surrounding automation hardware.
