Product Description:

The CSH01.1C-S3-EN2-MA1-MD2-S2-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat and supplied as part of the CSH Advanced Controllers series. Installed on an IndraDrive power module, it handles motion processing, field communication, and safety monitoring for multi-axis machines, packaging lines, and assembly stations. By managing setpoint generation, feedback evaluation, and coordinated axis commands, the unit bridges the PLC layer and the drive inverter in industrial automation architectures, while its onboard analog and digital I/O reduce the need for external signal modules.

At the hardware level, the control section draws only 7.5 W, so temperature rise stays modest inside tight drive cabinets. Motion data are exchanged through the master port, which uses Sercos III to provide deterministic fiber-optic communication for multi-axis rings. The feedback socket supports EnDat 2.1 / 1 Vss / TTL, allowing mixed encoder types to connect without converters. Machine-state signals reach the CPU through 16 digital inputs, and the unit also provides 16 transistor outputs for solenoids or relays. The certified Safe Motion (SIL2 / Cat. 3 PL d) function intervenes to cut torque or clamp speed when an emergency stop, guard switch, or light curtain is activated.

Process-related analog values are generated with an 8-bit D/A converter that produces a step size of 19.5 mV per increment, which is adequate for proportional valve control and low-speed positioning. Sensor signals entering the MA1 board are digitized with 12-bit resolution, giving 4096 discrete steps across the ±10 V range for closed-loop accuracy. The enclosure occupies only 49.5 mm of rack width, stands 241 mm tall, and extends 103 mm in depth, so multiple sections can be stacked side by side inside a standard control cabinet. Two built-in analog outputs, two analog inputs, and an RJ11 six-pole SSI connector complete the local interface set without expanding the footprint.
