Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PB-EN2-NNN-MA1-L1-S-NN-FW as part of the CSH Advanced Controllers series. The unit is a plug-in control section for IndraDrive converters, where it executes interpolation, axis synchronization, and diagnostic routines for servo drives used in packaging lines, machine tools, and material-handling stations. By combining fieldbus communication, encoder processing, and local analog channels, it supplies the deterministic command layer required for precise, closed-loop motor control in automated production cells.

Two differential analog inputs and two analog outputs form the local I/O extension, allowing quick coupling of torque or speed references from external sensors. Each input accepts a range of ±10 V and presents a high impedance of 1000 kΩ, reducing loading errors. The conversion has a resolution of 12-bit, which yields 4096 discrete steps for fine scaling. The outputs reproduce the same ±10 V span into loads down to 1 kΩ while keeping the same resolution. For plant-wide coordination, the controller interfaces with the PROFIBUS-DP network, exchanging cyclic telegrams with PLCs at configurable baud rates. During normal operation, the electronics draw only 7.5 W, minimizing cabinet heat.

The control electronics are powered from a logic rail of DC 24 V, and an initial inrush of 4 A must be provided by the supply to charge internal capacitors. Motion feedback is processed through the multi-protocol encoder interface that accepts EnDat 2.1 / 1 Vpp / 5 V TTL signals. The board energizes these transducers with a regulated 5.0 V feed and can deliver up to 350 mA of sensor current. Integrated safety uses a starting lockout rated as Stop Category 0, and the lockout channel expects 24 V logic at 3 mA so the drive output stages remain disabled until the machine safety circuit is cleared. These electrical limits affect wiring practice, fuse sizing, and controller startup.
