Product Description:

The CSH01.1C-CO-ENS-NNN-MD1-L2-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive stack, the module handles motion calculation, safety monitoring, and fieldbus interfacing, enabling coordinated drive behavior for packaging machines, handling systems, and other factory automation cells. It sits between the power stage and the machine PLC, generating setpoints from application code and forwarding real-time feedback to supervisory systems.

Its differential analog input accepts signals of ±10 V, allowing process values such as torque limits or external speed references to be injected without scaling. On the CANopen master port, the controller can address up to 127 nodes, permitting extensive decentralized I/O or drive networks. The separate DeviceNet channel supports 64 nodes, giving flexibility for installations that use that protocol. A front-mounted D-Sub 15-pin socket passes sensor signals to the integrated encoder interface. TTL probe inputs are sampled up to 400 kHz, so high-resolution incremental encoders can be tracked without loss of edge information.

The controller sources encoder power at 500 mA from an isolated 12 V rail, supporting SinCos, Hiperface, and IndraDyn sensors through 1 Vpp or TTL channels. The MD1 expansion on this variant brings 12 digital inputs and eight sourcing outputs for local interlocking and timing tasks. Its integrated Safe Torque Off complies with SIL3 / Cat. 3 PL e ratings, allowing the drive system to meet machinery safety standards without external relays. Mechanical integration is simplified by the compact footprint of 241 × 49.5 × 103 mm, so multiple sections fit side by side in a control cabinet. The STO path is evaluated at 24 V and 3 mA, and a service RS-232 port is provided for parameter access when fieldbus traffic is unavailable.
