Product Description:

The CSH01.1C-PL-EN2-NNN-NNN-NN-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Positioned between motion-sequencing PLCs and power inverters, this controller computes axis commands, manages encoder feedback, and supervises discrete machine signals so that servo drives follow precise speed, torque, or position targets in automated production cells. It also includes a parallel control interface for high-speed bit-level communication, which supports coordinated signal exchange with connected automation hardware.

An input stage with a 160 kΩ impedance minimizes loading on external signal generators, while the analog output delivers 5 V, 1 mA for reference transmission to legacy drive components. Fast regulation is achieved through a 125 µs current-control cycle, which continuously updates the drive model for rapid response. Discrete actuators such as contactors can be driven directly from the controller because its transistor outputs are rated at 24 V DC, 0.5 A. On power-up, the supply network sees an inrush limited to 4 A, reducing stress on upstream 24 V supplies. Additional resources include a 3 mA digital input current for each opto-isolated channel and separate PL (1 W) and EN2 (6 W) module power budgets that keep diagnostic functions alive even when axis power is disabled.

For relay-driven loads, the board provides a change-over contact rated at 24 V DC, 1 A, ensuring galvanic isolation from logic electronics. Position-capture tasks benefit from a maximum input pulse width of 100 ms, allowing accurate edge recognition on slow sensors. The unit’s own consumption stays within 7.5 W at the nominal 24 V bus, which helps control-cabinet thermal management during continuous operation. Integrated encoder supplies deliver 5.0 V at 350 mA and support EnDat 2.1 / 1 Vpp / 5 V TTL feedback formats, so both absolute and incremental transducers can be used without external adapters. The unit does not include integrated safety technology.
