Product Description:

The CSH01.1C-PB-ENS-EN2-MD2-NN-S-NN-FW is a single-axis motion controller from Bosch Rexroth Indramat’s CSH Advanced Controllers series. The module is intended for cabinet installation where it supervises torque, speed, and position loops on servo drives while also exchanging status data with higher-level automation systems. By combining embedded drive control with extensible I/O, the unit streamlines decentralized machine architectures that demand synchronized motion and rapid fieldbus updates.

The controller runs from a regulated DC 24 V supply and its electronic core draws only 7.5 W during steady operation, minimizing cabinet heat dissipation. Drive and PLC communication takes place over PROFIBUS-DP, so telegrams for setpoints or diagnostics can be delivered in real time through a single shielded trunk. An inrush limiter keeps startup current near 4 A, protecting upstream power supplies. Pulse inputs on the MD2 expansion channel are accepted up to a maximum width of 100 ms, allowing capture of slow edge-driven events such as part-in-place sensors. The standard control panel provides membrane keys and a small display for parameter access, while the external I/O supply is isolated to prevent ground loops. Encoder channel 1 reads IndraDyn, HIPERFACE, or 1 Vpp signals through the standard evaluation interface, and channel 2 accommodates EnDat 2.1, 1 Vpp, or 5 V TTL feedback, giving flexibility when mixed motor types share one machine. Digital I/O and SSI encoder evaluation can be added through the designated extension slot.

A high-density 44-pin D-Sub (HD) connector carries the MD2 I/O signals, and each digital input on this header sinks about 3 mA, permitting direct connection to common proximity switches. Program and parameter sets reside on the removable PFM02.1 memory card, so the controller can be set up without a laptop. The secondary encoder supply delivers 5 V at the socket, eliminating the need for separate power leads to the feedback device. Because the design omits integrated safety technology, any required STO or SS1 functions must be provided by external modules.
