Product Description:

The CSH01.3C-CO-ENS-NNN-CCD-L2-S-NN-FW is a control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in modular drive cabinets, the unit coordinates servo axes and gathers field signals so that motion sequences remain deterministic. As a controller section, it provides processing power, low-level I/O handling, and network gateways, forming the bridge between higher-level PLC tasks and the power electronics that actuate motors and other devices throughout automated lines. This role places the module at the core of packaging, printing, and material-handling stations that require precise command generation and diagnostic feedback.

Signal conditioning on the board is tuned for high-speed events, and its 5 V TTL capture input accepts frequencies up to 400 kHz, allowing direct connection of incremental encoders or barcode scanners. Each analog input presents 160 kOhm of resistance and is digitized in steps of 1.23 mV/inc, while the corresponding outputs resolve commands at 19.5 mV/inc. Two analog output channels deliver setpoints with 1 mA source capability, and the digital outputs can switch loads drawing up to 500 mA. Base electronics draw only 8.5 W, which helps keep cabinet heat generation low. An internal sensor bus also forwards position data and receives power from an encoder rail that provides 500 mA.

Host integration is flexible because motion commands pass over CANopen/DeviceNet fieldbuses, and cross-frame data exchange uses the Ethernet physical layer specified by IEEE 802.3 with a dedicated 100Base-TX engineering port for setup. When participating in a multi-drive rack, the section assumes the master role and propagates synchronization telegrams to all slaves. Diagnostic access is available through an RS-232 link that may extend 15 m without repeaters. For person and machine safety, the hardware applies Safe Torque Off logic, while feedback supplies are stabilized at 11.6 V to protect sensitive encoders.
