Product Description:

The CSH01.1C-CO-ENS-EN2-MD1-NN-S-NN-FW control section is part of the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Mounted on an IndraDrive power module, it coordinates axis commands, handles feedback from multiple encoder formats, and distributes I/O so that packaging, printing, or handling equipment can execute deterministic motion cycles. Its control functions are intended for applications that need synchronized motion and fast signal exchange between the drive and connected machine devices. It also lets one drive assembly manage motion feedback and local machine signals without separate interface hardware.

Field-level communication is handled through the controller’s CANopen / DeviceNet interface, allowing drive parameters to be mapped directly onto the plant network. Internal consumption is limited to 7.5 W, which simplifies cabinet thermal calculations. During power-up, the section draws an inrush of 4 A for a maximum of 100 ms, after which steady-state current falls to background levels. One analog output delivers up to 1 mA for setpoint or diagnostic signals. The MD1 extension provides twelve digital inputs, eight digital outputs, and sink capability of up to 0.5 A per output, so valves, sensors, or light curtains can be wired without extra relays. Encoder Interface 1 accepts IndraDyn, HIPERFACE, or 1 Vpp sine-cosine feedback, while Encoder Interface 2 works with EnDat 2.1, 1 Vpp, or 5 V TTL sources.

The secondary encoder supply (En2) supports cables up to 75 m; it delivers 350 mA at a stabilized 5.0 V so distant linear scales remain within signal tolerance. The main encoder supply (Ens) provides 500 mA at 11.6 V for resolver or HIPERFACE sensors. Output devices that exceed transistor capacity can be switched by the onboard relay block, rated at 24 V DC / 1 A. The relay block is useful when connected devices need isolated switching from the control section instead of direct transistor drive.
