Product Description:

The CSH01.1C-PL-EN1-EN2-MA1-S1-S-NN-FW is a motion-control processor board produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power section, the module interprets sensor feedback, issues velocity commands, and monitors safety channels so that servo axes follow programmed trajectories in assembly and material-handling machines without manual intervention. By uniting analog, digital, and serial links on a single card, it reduces wiring and simplifies integration within the drive system. This arrangement allows one board to manage motion tasks, feedback handling, and safety-related signal exchange in the same control platform.

For analog process variables, the board accepts an input span of ±10 V, presented on two differential channels that reject common-mode noise. The same span is available on its pair of outputs for command references. Conversion occurs at 12-bit analog resolution, giving 4096 steps for scaled signal handling. Program data moves to the PLC through a Parallel Interface that also carries 16 inputs and 16 outputs. Sensor feedback on the first encoder port is energized by an 18.2 Vpp carrier together with an 8 V DC track, so SinCos devices do not require an external supply. The second port supports EnDat 2.1 and is driven from the card’s 5 V line. Even under full load, the electronics draw only 7.5 W, which helps limit heat inside the cabinet.

All logic on the card is powered from the drive backplane’s DC 24 V feed, eliminating a separate external power supply. Internal galvanic isolation routes this bus to the dedicated safety terminals, where the enable line recognizes a 24 V / 3 mA signal before releasing the outputs. When the functional safety function grants motion, the card can source up to 24 V / 0.5 A on its safe output channel, which is sufficient for contactors or light curtains. Unused transistor channels remain available for user alarms or valve coils. The 8 V and 5 V encoder supplies are also short-circuit monitored to help prevent overload during operation.
