Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Mounted in an IndraDrive rack, it supervises one servo axis and closes the velocity, torque, and position loops for that channel. By translating field-level commands into precisely timed drive signals, the unit links plant PLC instructions to motor behavior and is used wherever coordinated single-axis motion is required in packaging, printing, or material-handling lines.

The module’s base consumption is 7.5 W, so cabinet thermal planning can assume only minimal self-heating under idle conditions. Motion commands reach the controller over the SERCOS II fiber-optic ring, and telegrams are exchanged at a data rate of 16 MBaud to keep loop update times short. One analog input and two analog outputs allow direct scaling of sensor values or analog actuators when discrete wiring is simpler than fieldbus mapping. Because the axis configuration is single-channel, all internal computing resources focus on that motor alone. For setup or service, an RS232 serial interface provides text-based parameter access independent of the real-time bus. When encoder signals must be recreated for another device, the emulation port can deliver square-wave feedback up to 1 MHz; its internal filter limits incoming encoder frequencies to 500 kHz so overspeed faults are reliably detected.

Additional feedback handling features round out the profile. The encoder supply can source up to 500 mA at a regulated 11.6 V, and it presents an input impedance of 120 ohms for differential lines, matching most resolver or sine-cosine transducers. Cable runs to external evaluation electronics may extend to 40 m without signal loss, and format conversion supports incremental or SSI streams as well as feedback from IndraDyn motors and Hiperface sensors. The Safe Torque Off function removes drive power without using mechanical relays, providing a certified method for category-compliant shutdown.
