Product Description:

The CSH01.1C-SE-EN2-NNN-MD1-L1-S-NN-FW is a motion-logic controller module manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in IndraDrive power sections, the board coordinates axis control, fieldbus exchange, and safety interlocks for industrial automation cells. It accepts feedback from servo drives and issues deterministic command sequences that synchronize position, velocity, and I/O processing in multi-axis machines.

Real-time communication with the drive system is handled through the SERCOS II optical ring, allowing cycle-synchronous data exchange. An initial surge of 4 A is the inrush current when the module is energized, so line protection must accommodate that transient. Analog process values are sourced on a channel delivering 1 mA, which is suitable for high-impedance measurement circuits. For serial setup, the integrated RS-232 port supports rates up to 115 kBaud and cable lengths up to 15 m, allowing diagnostic consoles to be placed outside the cabinet. The MD1 extension provides 12 digital inputs and 8 digital outputs, and the output stages include a relay contact rated at DC 24 V / 1 A for field devices that require galvanic isolation. The safety architecture includes a starting lockout wired to a D-Sub 9-pin female connector and removes torque-enable signals until all risk conditions are cleared. A maximum pulse width of 100 ms on the safety line is tolerated without a fault response.

The feedback channel is prepared for the EnDat 2.1 / 1 Vpp / 5 V TTL interface, and it powers transducers with 350 mA at a stabilized 5 V to support clean encoder signals over long runs. Sensor wiring that uses sense conductors can reach 75 m, while standard cabling without sense must remain within 50 m to keep voltage drop within limits. These cable lengths allow the controller to be mounted farther from the servo motors while maintaining stable feedback transmission, and they also support longer routing paths through energy chains without additional boosters.
