Product Description:

The CSH01.1C-S3-ENS-NNN-MD1-L1-S-NN-FW is a single-axis control section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It occupies the extension slot of an IndraDrive modular drive and delivers the logic layer that links field networks with drive power stages. This arrangement keeps motion control functions inside the drive system instead of relying on a separate external control module. In an automation cell, the unit coordinates motion profiles, diagnostic feedback, and real-time safety interlocks for servo axes, conveyors, or handling stations, allowing machine PLCs to offload time-critical tasks to the drive.

The control communication channel follows the SERCOS III protocol, so real-time telegrams share a common timing domain with the drive at sub-microsecond jitter. Two RJ-45, 8-pin ports comply with the IEEE 802.3 standard and support line or ring topologies. Digital outputs on the MD1 expansion can switch loads up to 500 mA per channel, while the encoder interface uses the ENS format and receives position data through a D-Sub 15 female connector. The feedback electronics supply the measuring device with 11.6 VDC and draw up to 500 mA. For discrete sensing, the MD1 board offers 12 isolated digital inputs that accept 24 V logic from limit switches or proximity sensors.

Complementary control resources include 8 sourcing digital outputs on the MD1 board, an onboard set of 11 additional digital inputs, one differential analog input, two ±10 V analog outputs, and four lines that the user can configure as either input or output. That mix of discrete, analog, and serial signals allows the controller to connect directly to common machine sensors and peripheral devices. Serial diagnostics are handled through an RS-232 service port that reaches a throughput of 115 kBaud. Machine availability is protected by the integrated Starting Lockout function, which prevents unintended motor energization until safety prerequisites are met.
