Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-S2-S-XP-FW is a modular control section from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed inside an IndraDrive power unit, it handles real-time axis coordination, fieldbus exchange, and integrated safety so that servo drives, I/O, and supervisory PLCs remain synchronized within automated packaging, machining, or material-handling cells. By combining deterministic communication with onboard motion functions, the section replaces stand-alone PLC layers in decentralized architectures.

Two ±10 V analog channels can source up to 1 mA each and drive loads down to 5 kΩ; their granularity is 19.5 mV/inc, allowing fine torque or velocity trimming. Network traffic to the drive stack occurs over SERCOS III, routed through an RJ-45 8-pin port that supports line or ring topologies. The section accepts encoder feedback on a D-Sub 15 connector; the supply rail of 11.6 V DC powers external sine-cosine or EnDat sensors, while incoming differential tracks are filtered at 500 kHz to reject higher-frequency noise. Fast position latching can also be performed with TTL probes up to 400 kHz. When a serial service interface is preferred, an RS-232 link up to 15 m is available for parameter backup and diagnostics.

The Md2 expansion on this variant provides 16 digital inputs and 16 digital outputs that share a D-Sub HD 44-pin receptacle, permitting high-density wiring to sensors and solenoid valves controlled by the motion kernel. For distributed position transducers, an SSI port on an RJ12 6-pin jack supports cable runs to 40 m at 1 MHz, matching the timing budget created by the encoder cutoff and TTL capture paths. Integrated safety relays switch motor-enable lines or external contactors at a rating of 24 V DC, 1 A, completing the hardware interlocks required for Category-based stop functions while leaving the primary SERCOS channel undisturbed.
