Product Description:

The CSH01.1C-PL-EN2-MEM-MA1-NN-S-NN-FW motion-logic controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It acts as the central processing module in multi-axis drive packages, running position loops, managing fieldbus traffic, and delivering time-critical machine commands to connected inverters and I/O cards. By consolidating axis control and general automation tasks in a single slot, the unit reduces cabinet count and supports compact machine layouts in industrial handling, packaging, and assembly systems.

With a base power draw of 7.5 W, the controller imposes a modest thermal load on the cabinet power rail. During startup, the supply must withstand an inrush of 4 A that lasts roughly 100 ms, and this pulse should be considered when sizing fuses or soft-start devices. Once initialized, each of the 16 transistor outputs on the PL section can source up to 0.5 A, allowing direct switching of relays or opto-isolated loads. The MA1 option board furnishes two differential analog inputs and two analog outputs referenced to a nominal 5 V level, and it digitizes feedback with a resolution of 12-bit. These channels give the axis software access to process variables such as pressure or speed without external converters.

The PL front end also reserves 16 digital input channels for sensors such as proximity switches, each referenced to the shared 24 V logic rail. Axis feedback arrives through the EN2 interface, which provides a 5 V encoder supply and maintains signal integrity over cable runs up to 75 m when sense lines are used. High-speed latch or cam functions rely on the MEM module, and its differential outputs operate to 1 MHz while remaining stable across extension cables of 40 m. For setup and diagnostics, an RS-232 port supports transfer rates of up to 115 kBaud over patch leads not exceeding 15 m, enabling parameter downloads through a local serial connection.
