Product Description:

The CSH01.1C-PL-EN1-NNN-MD1-L1-S-NN-FW is an advanced motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drives and peripheral I/O in industrial automation cells, acting as the central processor for axis commands, feedback handling, and interlock supervision. The device provides integrated slots for communication and encoder interfaces so that machine builders can tailor a single board to multiple drive topologies. This arrangement lets one controller manage motion sequencing and discrete machine signals within the same control platform.

It draws 7.5 W of base power during idle, keeping cabinet heat dissipation low. Command and status data are exchanged through a Parallel Interface, which delivers deterministic timing between the controller and upper-level PLCs. The MD1 extension card offers 12 digital inputs and eight digital outputs; the inputs accept 24 V signals and can be time-stamped for synchronous motion capture. The integrated encoder supply delivers 8 V to resolver or HSF transducers, eliminating external sensor power wiring. For the safety lockout line, the unit accepts a pulse with a maximum width of 100 ms; any longer transition forces a controlled shutdown.

The PL expansion doubles the field wiring capacity with 16 digital inputs and the same number of digital outputs for valve coils, relays, or barcode triggers. During startup, the power rail experiences a typical inrush of 4 A, so supply breakers can be sized to prevent nuisance trips. Serial diagnostics are handled over RS-232, and cable runs may extend 15 m while sustaining data rates up to 115 kBaud. Resolver feedback is energized with 18.2 Vpp at a carrier frequency of 4 kHz, permitting reliable shaft position tracking under electrical noise. A lockout monitoring current of 3 mA verifies safety relay continuity before motion is enabled.
