CSH01.1C-PL-EN1-EN2-NNN-S2-S-NN-FW

The CSH01.1C-PL-EN1-EN2-NNN-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in an IndraDrive power unit, it governs drive behavior through position loops, velocity loops, and integrated Safe Motion functions that meet machinery safety requirements. By embedding field communication and axis supervision on one board, it streamlines installation and reduces the number of separate modules normally required in multi-axis automation cells.

The EN2 feedback channel furnishes an encoder rail of 5.0 VDC and can deliver up to 350 mA, allowing simultaneous support for high-resolution encoders that draw more current than standard TTL devices. Sixteen parallel digital inputs and sixteen digital outputs give the PLC direct, high-speed influence over machine interlocks; the shared value of 16 per direction limits wiring complexity while still covering typical sensor and actuator counts on a single axis. All I/O pins are routed through a D-Sub 37-Pin connector, so shielded ribbon cabling can be attached without custom terminations. For resolver feedback the board drives the primary winding with a carrier of 4 kHz, a frequency high enough to minimize phase shift while remaining within the bandwidth of standard resolver transducers. A built-in RS232 serial channel provides parameter access during commissioning or troubleshooting without occupying the real-time bus.

Mechanical size also influences cabinet layout: the card is only 49.5 mm deep, 241 mm high, and 103 mm wide, so it can slide beside other controller sections on the same rail. Resolver secondary circuits are energized with 18.2 Vpp to ensure a strong return signal for precise angle calculation even through long motor cables. Safety wiring terminates on the X41 female 9-pin D-Sub, and the Safe Motion firmware monitors speed and position internally, eliminating extra relays. Together these electrical, dimensional, and safety attributes allow the module to fit tightly controlled panels while still handling complex motion tasks.
