Product Description:

The CSH01.1C-PB-ENS-MA1-MD1-S2-S-NN-FW is a modular motion controller produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It occupies the control slot in IndraDrive systems, coordinating axis commands and fieldbus traffic for automated machinery. By combining feedback processing, high-speed communication, and integrated safety on a single card, the controller supports deterministic command execution between the drive inverter, supervisory PLCs, and local I/O modules. This layout lets one control section manage motion data, signal exchange, and safety-related monitoring without requiring separate interface hardware in the same slot.

Fieldbus communication is handled through PROFIBUS-DP, presented on a D-Sub 9-pin female connector so the board can exchange cyclic and acyclic data without external gateways. For position feedback, it offers an encoder port that accepts IndraDyn, HIPERFACE®, 1 Vpp signals and powers the sensor at 12 V. The MA1 mezzanine section supplies two differential analog inputs that tolerate ±10 V and convert them with a resolution of 12 bits. Corresponding outputs provide the same voltage span and bit depth for drive-level torque or speed commands. Digital processing is managed on the MD1 module, which provides 12 opto-isolated inputs for limit switches or cam triggers and 8 high-side transistor outputs for status lamps, relays, or pilot valves. This combination allows the controller to handle analog references and discrete machine signals within the same drive platform.

Each MD1 output can source up to 0.5 A, allowing direct actuation of small solenoids while protecting the logic circuitry from overload. For higher current loads, the card includes a form-C relay whose contacts are rated at DC 24 V / 1 A, providing an isolated path for emergency-stop chains or system enables. The built-in Safe Motion technology supervises velocity and position internally, reducing the need for external safety relays. Diagnostics and service access can be handled over the RS232 port, and the two-channel MA1 structure keeps analog input and output routing organized.
