Product Description:

The CSH01.1C-SE-EN2-MEM-MA1-S1-S-NN-FW is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. This controller forms the core of a drive package by processing position feedback, generating command values, and exchanging real-time data with higher-level PLCs. Its task in industrial automation is to synchronize servo axes, monitor safety inputs, and deliver analog references to actuators without requiring additional interface cards.

The onboard analog block accepts signals in the range of ±10 V and digitizes them with 12-bit resolution for internal processing. Field devices connect through 2 differential inputs, and the controller returns signals through 2 analog outputs for closed-loop tasks such as tension or pressure regulation. Command and diagnostics are exchanged over the deterministic SERCOS II fiber channel, allowing cycle-synchronous updates between the controller and drive in multi-axis platforms. When an external position transducer is required, the built-in emulation port can recreate Absolute SSI or incremental tracks so that legacy drives receive the correct format without an auxiliary converter. Galvanic isolation protects upstream electronics, and a load resistance of 35 Ω ensures compatible line impedance for quadrature receivers.

The emulated encoder signal can travel up to 40 m without degradation and toggles at rates up to 1 MHz, supporting fast turntables and linear motors. A local encoder supply of 5.0 V DC is provided and can source 350 mA, eliminating a separate power rail for most feedback devices. EnDat 2.1, 1 Vpp, and 5 V TTL formats are accepted on the feedback inputs, simplifying use across mixed sensor types. Safety relays wired to the unit are energized through a 24 V / 3 mA input circuit, and solid-state outputs can switch loads up to 24 V / 0.5 A for gate interlocks or contactor coils.
