Product Description:

The CSH01.1C-SE-EN2-NNN-NNN-S1-S-NN-FW control section is supplied by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed as the logic module on an IndraDrive power unit, it executes motion commands, manages feedback, and coordinates safety circuits for multi-axis servo systems. By integrating fieldbus, analog, and safety channels in a single plug-in board, the controller simplifies cabinet wiring and allows deterministic drive regulation in demanding industrial automation cells such as packaging, material handling, or pick-and-place machinery.

Primary communication with higher-level PLCs uses SERCOS II messaging carried through a Fiber Optic pair, ensuring jitter-free cyclic data exchange down to 250 µs. A service port based on RS232 supports local parameter backups and firmware downloads. The module offers two analog outputs that source up to 5 V at 1 mA, which is useful for speed references or transducer excitation. Feedback wiring is accommodated by the EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface, and the channel tolerates 35 ohm load resistance while furnishing a 5.0 V sense line that delivers 350 mA to power absolute or incremental encoders. Twelve digital inputs change state once the applied signal exceeds the 15 V standard input-on threshold, letting the drive detect limit switches or probe triggers without external conditioning.

Discrete drive reactions and personnel protection are handled through the Safety Technology I/O architecture. The safety connector is a D-Sub 9-pin female, and its input side expects 24 V / 3 mA signals from light curtains or e-stops. Two redundant semiconductor outputs can switch actuators at 24 V / 0.5 A, while an onboard relay rated at DC 24 V / 1 A is available for hard contact feedback to the machine control. Standard user outputs deliver up to 500 mA per channel, permitting direct linkage of indicator lamps or small solenoid valves. These combined features allow the control section to enforce safe torque off, speed limits, or drive enable sequences without external safety relays.
