Product Description:

The CSH01.1C-PB-ENS-NNN-MD1-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular IndraDrive power units, it executes axis control algorithms, manages local I/O, and exchanges motion commands with supervisory PLCs. Within an automation cell, it acts as the closed-loop processor that links feedback devices to drive power stages so that positioning, speed, and torque targets are met. This role allows the drive system to coordinate motion tasks while keeping control functions inside the axis module.

The control circuitry incorporates a Digital I/O extension that provides 12 x 24 V inputs and 8 x 24 V outputs for direct connection of sensors and actuators. For higher-level communication, it uses PROFIBUS, and the dedicated bus channel reaches 12 MBaud for low-latency data exchange with distributed controllers. The integrated encoder front end terminates on a D-Sub 15 connector and uses standard encoder evaluation with a signal bandwidth of 500 kHz for reliable processing of incremental or absolute signals. An internal supply rail delivers 11.6 V to the connected encoder, eliminating the need for an external power feed and simplifying field wiring. These interfaces allow the section to combine machine feedback, command traffic, and local device signals in one control path.

The encoder supply can source 500 mA, allowing operation of high-resolution devices that draw more current than typical TTL encoders. Service access and diagnostics are handled through the RS232 port, and this serial interface supports up to 115 kBaud over cable lengths of 15 m. A latch input accepts pulses at 400 kHz, enabling precise capture of probe events during fast motion sequences such as registration or cut-to-length control. The standard front control panel provides parameter editing and status LEDs, but the unit incorporates no safety technology, so safety monitoring or STO functions must be provided by external hardware or separate safety drives.
