Product Description:

Bosch Rexroth Indramat produces the CSH01.1C-S3-EN2-NNN-MA1-S1-S-NN-FW, a single-axis control card in the CSH Advanced Controllers series. The card plugs into IndraDrive power stages and handles axis regulation, fieldbus communication, and local safety processing inside industrial automation cabinets. Its role is to translate motion commands from a plant-level PLC into synchronized position, velocity, and torque references for servo or spindle drives while simultaneously capturing feedback from the attached encoder. This consolidates high-speed closed-loop control within the drive frame and reduces external wiring.

On the analog expansion designated MA1, the controller offers two differential input channels that accommodate a bipolar ±10 V signal. Each channel is digitized with a 12-bit converter, so processes such as tension control or hydraulic positioning receive adequate resolution without oversampling. Two matching output channels reproduce commands across an identical voltage span for actuator drivers. Real-time motion data are exchanged with the higher-level system over SERCOS III, and the connection uses a shielded RJ-45 (8-pin) plug on the front panel. For feedback, the card supplies the encoder port with 5.0 V DC at up to 350 mA, permitting EnDat 2.1, 1 Vpp, or 5 V TTL transducers to operate without an auxiliary power rail. Together, these parameters suit medium-power servomotor axes that require precise voltage-mode I/O and deterministic bus timing.

The front-mounted D-Sub 15 socket groups incremental and absolute encoder lines beside the Hall signals, which reduces the chance of mismatched pin connections. Safety circuits switch contactors through a relay rated at 24 V DC / 1 A. A built-in RS232 port allows low-level parameter access when the real-time network is offline.
