Product Description:

The CSH01.1C-PB-ENS-MEM-MA1-L1-S-NN-FW is a single-axis motion controller card manufactured by Bosch Rexroth Indramat for modular drive racks in the CSH Advanced Controllers series. The card functions as the central processing and interface layer between the IndraDrive power section and higher-level automation equipment, issuing velocity and position commands while exchanging fieldbus data with the plant control system. In industrial automation, it forms part of coordinated servo systems and provides signal conditioning, protocol handling, and embedded safety for synchronized axes in packaging, handling, and machining lines.

This unit accepts analog feedback on two differential input channels that each accommodate signal swings of ±10 V, allowing direct connection of standardized process transducers. Conversion is carried out with 12-bit resolution, so the controller can detect 1 part in 4096 across the selected span. Two analog outputs reproduce setpoints or diagnostic variables over the same span and can be wired to external indicators or auxiliary drives. Digital communication to the automation controller is handled by a 12 MBaud backplane and a PROFIBUS-DP interface, enabling cyclic command exchange and diagnostic telegrams within deterministic network slots.

Position-loop signals are processed through the standard encoder evaluation circuit, which supports incremental and SSI emulation, delivers an isolated supply of 11.6 VDC, and can source up to 500 mA for IndraDyn, Hiperface, or 1 Vpp encoders. Captured counts are forwarded to the motion logic with a peak retransmission rate of 1 MHz, and cabling between the master encoder and this module can extend to 40 m without signal repeaters. A starting lockout safety function prevents uncontrolled motor energization until all enable inputs are validated, and the integrated memory channel stores configuration data so the controller powers up with previously stored parameters.
