Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-L2-S-XP-FW is a drive controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on a Rexroth power stage, it serves as the central processor that interprets encoder data, supervises safety inputs, and exchanges motion commands with plant networks. Its role in industrial automation is to synchronize multiple servo axes, issue real-time trajectory updates, and forward diagnostic information so that packaging machines, gantry systems, or assembly lines run with repeatable speed and position accuracy.

The encoder interface is designed for low-noise signal transfer. It terminates differential lines with an impedance of 120 ohm and feeds the sensor with a typical supply of 11.6 V. Up to 500 mA is available, allowing incremental or absolute encoders that require substantial current for illumination or internal electronics. Position words are digitized by an ENS converter that works at 12-bit resolution, and incremental TTL tracks are accepted at frequencies up to 400 kHz, supporting high-speed linear motors. A service port using the RS-232 protocol reaches data rates of 115 kBaud, allowing direct parameter access without an external gateway.

Field wiring passes through the MD2 expansion, which uses a D-Sub HD (44-pin) connector to carry 16 digital inputs and 16 digital outputs for valve manifolds, sensors, and lamp stacks. Ethernet motion communication is handled by the S3 interface, and its two ports are presented on an RJ-45 (8-pin) housing that complies with the IEEE 802.3 standard. The internal switch is rated for 2 channels, which supports line-topology wiring between networked devices. The RS-232 lead may span up to 15 m inside a cabinet. Safe torque off signals connect through a separate D-Sub (9-pin) plug and draw only 3 mA at the required 24 V DC supply.
