Product Description:
The CSB02.1A-ET-EC-CN-L3-NN-NN-FW belongs to the CSB Drive Controllers series from Bosch Rexroth Indramat. It functions as a motion-control platform that conditions low-voltage command signals, supervises feedback from multiple encoder formats, and issues gate commands to external power sections. In automated cells, it bridges fieldbus traffic and motor regulation, allowing precise position, velocity, and torque control without separate interface cards. The control section also manages communication and feedback processing in one module, which helps keep axis coordination centralized.
The single differential input channel accepts ±10 V analog references and is filtered at 1.3 kHz, while its conversion granularity is 14-bit. Together, these values let a PLC transmit finely stepped speed or torque commands with minimal phase delay. Seven digital terminals, identified as 7 inputs, support fast edge detection for limit switches or homing signals. A built-in Multi-Ethernet node is compatible with 100Base-TX cabling and reaches the network through a shielded 8-pin RJ-45 connector, eliminating the need for external communication hardware. When legacy connectivity is required, the optional CAN interface uses CANopen. The controller’s multi-encoder port synchronizes resolver, EnDat, or Hiperface feedback, and a pair of probe inputs allows position latching during metrology routines. Two spare option bays accommodate future I/O or safety upgrades.
A maximum capture width of 1 ms for the probe channels supports registration marks on high-speed webs and other time-sensitive detection tasks. Internal circuitry draws only 17 W at idle, and all logic is supplied from an external rail rated at 24 V DC. The relay output can switch loads up to 30 V, enabling contactor control without an interposing device. Safe Torque Off is implemented in hardware so motor power can be removed while fieldbus communication remains available. This arrangement supports safe machine stops without interrupting diagnostic or network functions.
