Product Description:

The CSH01.1C-SE-ENS-NNN-NNN-L1-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Within an automation cell, this controller coordinates drive axes, exchanges motion data with higher-level PLCs, and manages local I/O through its integrated fieldbus interface. By consolidating sequencing and servo synchronization in one module, it simplifies cabinet layouts and shortens system response time.

The unit draws its operating logic from a control supply of 24 V DC, while its basic power consumption remains at only 7.5 W, helping keep cabinet thermal load low. Motion commands and diagnostic traffic travel over the SERCOS II fiber-optic ring, giving deterministic communication for multi-axis drives. Two programmable analog outputs provide reference signals up to 5 V with a granularity of 19.5 mV per increment, suitable for proportional valves or sensor excitation. TTL command channels accept edge rates up to 400 kHz, and single-shot tasks can be gated with a maximum pulse width of 100 ms. When switching external circuits, an onboard relay supports low-voltage DC loads up to 1 A. The Starting Lockout safety function prevents uncommanded motion after power-up, and a typical inrush current of 4 A must be considered when sizing the control supply. The asynchronous serial port supports cable runs up to 15 m for local diagnostics.

Differential encoder inputs present an impedance of 120 Ω to minimize signal reflections, and the A/D converter resolves position feedback with 12-bit resolution per sample for medium-accuracy axis control. The encoder interface can source up to 500 mA at 11.6 V, allowing direct power of optical or magnetic transducers. Configuration uploads or local setup can use the RS232 channel, which reaches a line speed of 115 kBaud for quick data transfer.
