Product Description:

The CSH02.1B-CC-EC-CN-S4-EC-NN-FW is a motion and logic controller manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Mounted inside a drive cabinet, the unit coordinates multiple servo inverters, gathers real-time feedback, and issues deterministic setpoints for packaging, handling, and processing machines that rely on synchronized axis motion. It also embeds certified Safe Motion options that allow velocity and position monitoring without adding external safety relays. Because the controller sits above the individual drives, it can manage timing relationships between axes rather than leaving each inverter to react independently. This arrangement supports machines where motion sequencing and logic control must operate together during continuous production.

On the device front panel, a 5 V auxiliary rail delivers up to 500 mA to incremental or absolute encoders, removing the need for separate sensor supplies. The analog current input presents a 300 Ω load and is digitized with an effective resolution of 11 bits, giving precise process-value capture for pressure or torque loops. When the controller drives an external actuator through its voltage output, every increment equals 24 mV/incr, allowing fine reference trimming. Digital outputs can switch loads up to 500 mA, and the onboard relay can pass 30 VDC while isolating low-level signals from field wiring. These interfaces allow the controller to exchange both command and feedback signals directly with nearby machine devices.

Network integration is handled by a CANopen interface arranged in line topology, and termination is provided by a factory-installed 124 Ω resistor that matches cable impedance. Using standard D-Sub 9-pin plugs, the segment may stretch to 100 m at 500 kbaud and accept up to 127 nodes without repeaters. For fast drive communication, the controller acts as a SERCOS III master, streaming cyclic setpoints while passing safety telegrams. Safety channels observe a minimum input high level of 15 V and can source 350 mA on the dedicated safe outputs. The electromechanical relay rated for 1 × 10^8 cycles supports extensive switching life in high-duty machines.
