Product Description:

The CSH02.1B-CC-EC-ET-L3-DA-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. This compact control section is intended for multi-axis drive systems, where it processes motion commands, fieldbus data, and safety signals in a single module. By combining high-speed logic with integrated encoder monitoring, the part coordinates synchronous positioning and velocity loops for servo axes in packaging, printing, and handling equipment. This arrangement allows one controller section to supervise axis behavior and feedback handling without requiring separate external processing for each motion function.

The module provides an analog command range of ±10 V, allowing proportional speed or torque references to be delivered directly to the power stage. Each analog change is quantized at 24 mV per increment, using a converter with 14-bit resolution for precise setpoint generation. Internal electronics draw a base power of 17 W, while the logic circuits are energized from a 24 V DC control supply that is common to the host cabinet. Motion commands are exchanged over a SERCOS III master interface, and feedback from several encoder types is accepted through the built-in multi-encoder interface. A Multi-Ethernet option permits operation on PROFINET, EtherNet/IP, and EtherCAT networks, and an I/O extension slot supports additional digital or analog channels. The 4 µs probe pulse width supports time-aligned capture of position latches during registration and synchronization tasks.

For drive enable lines and general machine signaling, the digital outputs can source up to 500 mA per channel, and dedicated Safe Torque Off circuits provide emergency shutdown through separate safety outputs. Individual communication sections contribute to the power budget, with the Ec channel consuming 1.1 W, the Et channel adding 2.7 W, and L3 logic layers requiring 1.0 W. Total thermal load remains low, which helps simplify enclosure cooling in compact cabinets. Safe Torque Off disables motor energy without interrupting fieldbus communication, so control status and network exchange remain available during a safety stop.
