Product Description:
The CSH01.1C-PL-ENS-EN2-MA1-L2-S-NN-FW is a single-axis motion and safety controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As the supervisory brain of a drive section, it exchanges position commands with servo inverters, executes user programs, and handles field-level sequencing in packaging, material handling, and converting lines. The hardware includes a standard control panel for local parameter entry, and its integrated Safe Torque Off channel eliminates external contactors when a category-rated stop is required. This combination lets one controller manage motion logic and safety-related stopping within the same drive architecture.
Its safety circuitry meets the SIL3 / Cat. 3 PL e classification, meaning internal redundancies are verified for hazardous motion stoppage. During continuous operation, the logic core draws only 7.5 W, so cabinet thermal load remains low. For machine status and interlocking, it provides 16 In / 16 Out lines on the parallel interface. The parallel interface supports direct exchange of machine signals without a separate discrete I/O module. Analog processing is handled on the MA1 board, where a 12 Bit converter resolves ±10 V signals for speed or tension loops. Despite these integrated functions, the housing spans just 49.5 mm across the front rail, allowing high controller density in multi-axis racks.
Mechanical clearances are set by a height of 241 mm and a depth of 103 mm, so the controller fits standard 300 mm enclosure frames while leaving space for airflow behind the backplane. Position feedback support is split between two isolated supplies: the primary encoder port delivers 11.6 V for IndraDyn or HIPERFACE sensors, and the secondary channel provides 5.0 V for EnDat 2.1 or TTL sources. This arrangement allows mixed-axis installations without external power taps and keeps encoder wiring straightforward inside the cabinet. Isolated supply levels also reduce the need for separate interface hardware when different feedback systems are used on the same machine.
