Product Description:

The CSH01.1C-PB-EN1-NNN-CCD-L1-S-NN-FW is a compact control section created by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It governs drive-based automation by processing analog feedback, issuing digital commands, and relaying fieldbus data to connected power stages. Within an installation, it acts as the central logic layer that times motion profiles, evaluates sensor values, and exchanges status information with supervisory PLCs. This arrangement lets one control section coordinate signal handling and communication tasks without adding a separate motion processor in the panel.

This controller draws a base power of 7.5 W during steady operation and can withstand an inrush of 4 A when the supply is first applied. Digital transistor outputs are rated for 0.5 A per channel, while the onboard relay channel can switch loads up to 1 A for auxiliary signaling. Analog monitoring circuits present an input resistance of 160 kΩ, allowing low-energy transmitters to be used, and their corresponding outputs are intended for a minimum load of 5 kΩ. Resolver feedback is accepted at a carrier frequency of 4 kHz with an excitation level suited to standard resolver sensing elements. The RS-232 service port supports speeds up to 115 kBaud, and cable runs can extend to 15 m without repeaters. A maximum pulse width of 100 ms is available on the fast counter, which helps the controller register short encoder gaps and similar brief events. That combination lets the unit manage discrete outputs, analog sensing, resolver feedback, serial service communication, and high-speed pulse evaluation from the same control section.

Module-level power budgets vary by installed interface. The PB fieldbus board dissipates 2 W, the EN1 Ethernet interface consumes 6 W, and the CCD option requires 1 W, so the total load depends on the fitted communication and option cards. Safety inputs are energized from an internal supply of 8 VDC at 250 mA, which removes the need for a separate external source for that circuit. These option-card losses add to the enclosure's thermal load alongside the base controller demand.
