Product Description:

The CSH01.1C-SE-ENS-MEM-MA1-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It functions as the central command board for IndraDrive power sections, coordinating servo axes, encoder feedback, and integrated safety in industrial automation cells. In an automated line, the unit converts high-level program instructions into synchronized torque, speed, and position references, enabling precise motion sequences across packaging, handling, or machine-tool stations. Its compact format allows direct mounting inside multi-axis cabinets without separate PLC hardware.

Electrical demand is modest, and the board consumes 7.5 W under nominal conditions, which helps limit heat dissipation. Command and feedback data move through the SERCOS II real-time ring, supporting cycle times down to 250 µs. The ENS encoder interface samples incremental signals with a 12 bit converter and can deliver 500 mA at 11.6 V to power external encoders, eliminating the need for an auxiliary supply. For edge-count applications, the TTL capture channel tolerates input bursts up to 400 kHz, maintaining position integrity during rapid moves. Absolute-position devices connect through the MEM slot, which supports the SSI protocol so the drive can read single-turn or multi-turn codes without additional gateway modules.

The optional MA1 module adds 2 differential channels of analog input plus two analog outputs, both converted at 12-bit resolution for velocity or pressure setpoints that do not traverse the fieldbus. When absolute data are retransmitted to external sensors, the MEM driver supports a burst frequency of 1 MHz, which suits high-resolution SSI encoders. Safety functions rely on Safe Motion logic and accept control commands at 24 V while drawing only 3 mA, and emergency stop relays may be driven directly by the S2 stage, which sources 0.5 A to downstream contactors. A single-line front panel display allows local status viewing without connecting a laptop.
