Product Description:

The CSH01.1C-SE-ENS-EN1-MD1-L1-S-K1-FW is a motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit mounts beside Rexroth power inverters and coordinates multiple servo axes through a real-time fiber-optic ring, supplying centralized command processing for packaging, printing, and material-handling machines. It evaluates feedback, exchanges fieldbus data, and supervises safety interlocks so the connected drives can apply the requested speed and torque profiles without additional PLC hardware.

On its MD1 I/O expansion, the controller provides 12 sink/source digital inputs and 8 transistor outputs. Each output can deliver up to 0.5 A, which is enough to actuate contactors or indicator lamps directly. Analog process variables are accepted on a channel with an input resistance of 160 kΩ, minimizing sensor loading. Deterministic setpoint traffic with the drive amplifiers is handled by the SERCOS II interface. The En1 encoder port supports differential sin-cos signals, and its high-speed inputs present 10 kΩ resistance while using an internal 8 V, 250 mA source. A second Ens port is intended for TTL encoders; it loads the line with 120 Ω and can furnish 500 mA, supporting high edge-rate feedback devices without external power conditioning.

For setup and diagnostics, the controller includes a RS232 service port that allows cable runs up to 15 m without repeaters. Relay signaling is provided through a contact rated at DC 24 V, 1 A for motor-contactor or beacon interlocks. The Ens port offers a regulated 11.6 V supply and accepts incremental channels at up to 400 kHz, permitting precise position capture on high-speed linear axes. Functional safety is addressed by the built-in starting lockout mechanism, which keeps the drive-enable lines inhibited until all emergency-stop and guard-door conditions are cleared.
