Product Description:
The CSH01.3C-PB-ENS-MEM-CCD-L2-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a configurable drive controller module, it orchestrates motion axes and peripheral devices within automated machinery by managing fieldbus traffic, handling encoder data, and issuing synthesized command pulses. The unit is inserted into IndraDrive power sections, where it supplies real-time command processing that links servo drives to higher-level programmable logic controllers. Its modular format supports coordinated axis control and signal handling within a compact drive assembly.
Communication resources dominate the module’s hardware. Field control is handled over PROFIBUS-DP, and telegrams can be exchanged at up to 12 MBaud, allowing deterministic data cycles for axis coordination. A separate backplane slot hosts a SERCOS III Master channel so the controller can forward synchronized process images to distributed drives without involving the PLC. For digital test stands, the board produces an emulation stream that reaches 1 MHz, enabling drive replacements to be bench tested with high-resolution pulse trains. Despite these data rates, the core electronics draw only 8.5 W at idle, and the 4 A inrush current stays within standard cabinet fusing. A Safe Torque Off circuit disconnects gate drives immediately when an emergency signal is issued, which helps the control section support machine safety functions at the drive level.
Encoder support completes the signal path. Incremental or SSI formats are accepted through a differential receiver whose impedance is 120 Ohm, which helps prevent line reflections on long feedback cables. The sensor port supplies up to 500 mA from an isolated rail rated at 11.6 V, so multiturn encoders and external reference switches can share the same feed. For time-based events, the module measures pulse edges up to a maximum width of 100 ms, and a counter channel records TTL transitions at 400 kHz without missing edges. Encoder emulation can output identical incremental or SSI data, allowing the axis to broadcast its position to legacy motion controllers and other connected control hardware that still relies on conventional feedback formats.
