Product Description:

The CSH01.1C-CO-NNN-NNN-NNN-L2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on an IndraDrive power section, the card supplies motion processing, network interfacing, and integrated safety so servo drives can be coordinated from a central PLC. It interprets high-level commands and generates current-loop references in real time for packaging, handling, and forming equipment. The control section also supports synchronized machine behavior when several automated functions must operate within the same drive platform.

Power demand is modest, with a base draw of 7.5 W and an auxiliary Co-module requirement of 1 W, allowing the unit to share low-voltage back-plane supplies. A built-in bus terminator of 124 Ω matches the impedance of CAN networks, which helps prevent signal reflections on high-speed lines. Through its dual-protocol interface, the controller supports up to 127 CANopen nodes and 64 DeviceNet nodes, allowing one card to supervise sizable decentralized I/O groups across a machine. For service or diagnostic access, the RS-232 port transmits at up to 115 kBaud over cable lengths of as much as 15 m. During power-up, the logic section tolerates an inrush current of 4 A for about 100 ms, which is relevant when cabinet fusing is selected.

The housing measures 49.5 mm in width, 103 mm in depth, and 241 mm in height, so adjacent drive slots remain accessible in compact control cabinets. Its compact size helps the control section fit into dense drive assemblies without blocking nearby modules or cable routes. Functional safety is handled by a Safe Torque Off channel routed through a 9-pin D-Sub connector; when activated, it drives the power stage to a torque-free state and fulfills SIL3 / Cat. 3 PL e. This arrangement allows the safety function to be integrated directly at the drive level instead of relying on a separate external safety relay for torque shutdown.
