Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-SE-EN1-EN2-NNN-L1-S-NN-FW, a control section from the CSH Advanced Controllers series. The unit plugs into IndraDrive power modules and acts as the primary motion processor for multi-axis systems, synchronizing drives, encoder feedback, and safety I/O within a single rack slot. By executing positioning commands and fieldbus telegrams, it provides deterministic coordination of servomotors, making it suitable for packaging machinery, printing lines, and other factory automation where compact centralized control is required. This arrangement keeps motion control functions centralized while the connected power modules handle motor current delivery.

The controller accepts a supply of DC 24 V, and its logic circuitry draws only 7.5 W, minimizing cabinet heat. Communication with the drive system uses the real-time SERCOS protocol transmitted over fiber-optic cables, allowing high electromagnetic immunity and galvanic isolation. Two differential analog channels provide 2 analog outputs for proportional valves or servo amplifiers, while a typical inrush current of 4 A affects the sizing of the 24 V feeder and fuse. A single N/O relay contact, two probe inputs, and a standard control panel with a single-line display complete the local signaling resources without additional option cards. The built-in panel also gives the operator a direct way to view status information at the drive.

For axis feedback, Encoder Interface 1 accepts HSF and resolver signals, and Encoder Interface 2 accommodates EnDat2.1 / 1 Vpp / 5 V TTL, enabling mixed use of legacy resolvers and absolute optical encoders on the same controller. This combination supports machine layouts that use different feedback technologies on separate axes. The design also includes a maximum probe pulse width of 100 ms for reliable edge capture during fast metrology, and the safety architecture integrates a starting lockout function that is wired through a D-Sub 9-pin female connector. The section can therefore manage position evaluation, safe enable, and transient measurement without extra PLC cards.
