Product Description:

The CSH01.1C-PB-EN2-NNN-MEM-S2-S-XP-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It slides into an IndraDrive power unit and provides the central processor that executes motion commands, manages fieldbus data, and supervises safety functions. By translating drive parameters and PLC instructions into precise torque, speed, and position setpoints, the module enables coordinated multi-axis movement in packaging machines, material-handling gantries, and metal-cutting cells. Its compact form factor helps reduce panel depth in densely populated automation cabinets.

Electrical loading is modest; base power consumption is 7.5 W, while the incoming surge peaks at 4 A for an 100 ms pulse as the capacitors charge. The board communicates with higher-level controllers through the PROFIBUS-DP fieldbus, so telegrams for setpoints and diagnostics travel on the same cable that links other drive stations. A steady 24 V control supply keeps logic active, yet internal conversion steps reduce voltage for encoder circuitry; the incremental and absolute encoder port distributes 5.0 V reference power and accepts EnDat 2.1, 1 Vpp, or TTL signals. These inrush and steady-state values describe the electrical load and heat dissipation that the installation must accommodate.

The module also generates synthetic feedback for downstream devices. Its emulation channel supplies 20 mA differential current at up to 1 MHz so legacy controllers can receive position clocks derived from the actual motor encoder. The line may be terminated with 35 Ω because the driver can deliver an encoder output current of 350 mA without distortion. Encoder emulation can reproduce incremental pulses or an absolute word, while the built-in Safe Motion technology provides certified stop and limit functions.
