Product Description:
The CSH01.1C-SE-EN2-NNN-MA1-L1-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power unit, the section executes motion commands, coordinates feedback, and transmits status data to higher-level PLCs. By combining fieldbus communication and local analog I/O, the device serves as the central automation element for servo presses, pick-and-place gantries, and other multi-axis production equipment.
During operation, the control section draws an acknowledgment supply of 24 V / 1 A to energize its internal relays, while its logic circuitry consumes only 7.5 W of base power, minimizing cabinet heat dissipation. Network exchange with drive amplifiers and PLCs occurs through the SERCOS II fiber-optic ring, and the channel can be clocked up to 16 MBaud to achieve sub-millisecond cycle times for torque, velocity, and position loops. A single-line plain-text display on the front plate presents node address, diagnostic codes, and parameter values without external tools. The integrated starting lockout function removes torque-enable signals when safety interlocks are open, supporting category-compliant machine stops.
The module reads position feedback through the EnDat 2.1 / 1 Vpp / 5 V TTL interface; it also provides a stabilized sensor rail of 5.0 V at up to 350 mA so encoders remain powered during fast restarts. A separate 24 V, 3 mA lockout control input can be wired to external E-stop chains to force the same safety shutdown logic. The MA1 analog board offers two differential input channels accepting ±10 V process signals and two voltage outputs with an identical span; both directions are digitized at 12-bit resolution for consistent command granularity. These channels let the controller close external pressure, temperature, or flow loops without an additional I/O module.
