Product Description:

The CSH01.1C-SE-EN1-EN2-NNN-NN-S-XP-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Designed as a compact axis control platform, it coordinates drive tasks in distributed automation lines through SERCOS fiber-optic networking. The module integrates processing, fieldbus, and encoder channels in a 49.5 mm wide housing so that multi-axis functions can be added without expanding cabinet depth. It serves as the central motion node between higher-level PLCs and power inverters. Its control architecture keeps motion, feedback, and interface functions in one module instead of splitting them across separate cards.

Signal conditioning on the board starts with an analog input resistance of 160 kΩ, which protects upstream sensors by drawing negligible current. The analog output stage can source up to 1 mA, and its step size of 19.5 mV/inc permits finely scaled reference values for torque or speed loops. Base power consumption holds at 7.5 W, so internal heat rise stays limited even when the controller is idle. For proximity switches and photo-eyes, the integrated digital I/O rail provides 1.1 A of 24 V supply. Encoder socket X4 accepts HSF, RSF, or resolver feedback, while X8 reads EnDat 2.1, 1 Vpp, or TTL signals, allowing mixed feedback arrangements on the same platform. Communication with supervisory equipment is handled by a dedicated RS232 port, and the housing measures 241 mm in height and 103 mm in depth.

During start-up, the module can draw an inrush current of 4 A, so line fusing must accommodate that short surge. Each digital output channel is rated for 0.5 A, letting the board actuate solenoid valves or optically isolated relays directly. The EN2 encoder link supports cable runs up to 75 m without repeaters, which helps when motors are mounted away from the control cabinet. A probe pulse width of 4 µs aligns fast capture inputs with high-speed print-mark or registration applications. Separate encoder channels and direct digital outputs help the controller manage timing-critical machine events without extra interface hardware.
