Product Description:
The CSH01.1C-CO-ENS-NNN-MA1-L1-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive frame, it functions as the real-time command processor between a supervisory PLC and the drive’s power electronics. The card parses fieldbus telegrams, evaluates encoder feedback, and generates motion profiles so that multi-axis systems in packaging, material handling, or assembly machines can follow precise speed and position targets in automated production lines.
This card supports the dual-protocol CANopen/DeviceNet fieldbus interface. On the CANopen side, it can address up to 127 nodes, while the DeviceNet stack handles as many as 64 devices on the same network segment. An internal safety circuit provides a starting lockout stop that conforms to Category 0 for rapid torque removal when required. Feedback channels accept differential TTL signals up to 400 kHz, and the separate EnDat/SSI path filters encoder waveforms up to 500 kHz. A 120 ohm input resistance terminates the encoder line correctly and minimizes signal reflections. These data rates allow the controller to capture fine-grained position information without missing counts during high-speed machine cycles.
The onboard MA1 analog module offers two differential inputs and two outputs over a ±10 V range, and each conversion uses 12-bit resolution to transfer velocity or pressure setpoints with adequate granularity. Logic and I/O electronics are powered from a separate control rail of DC 24 V, and the same rail can deliver an acknowledge pulse rated at 24 V and 1 A for the L1 enable circuitry. External encoders can be supplied with 11.6 V at up to 500 mA, eliminating the need for a dedicated sensor power unit. This arrangement supports analog command exchange and encoder supply functions from the same control section.
