Product Description:

The CSH01.1C-PB-ENS-NNN-NNN-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Acting as the central processing card inside an IndraDrive system, it coordinates servo axes and peripheral devices in automated machinery. The module translates fieldbus commands into precisely timed drive signals while evaluating encoder feedback and handling integrated safety logic for packaging, material-handling, and general assembly lines.

At the core of the module, the base electronics draw only 7.5 W, so cabinet heat rise is limited. Network traffic moves through the PROFIBUS-DP interface, which is optimized for cyclic telegrams at up to 12 MBaud; the bus plugs into a D-Sub 9 female connector next to the diagnostic LEDs. Feedback signals from rotary or linear encoders arrive on a D-Sub 15 female socket and are interpreted by the unit’s standard encoder evaluation circuit. Those sensors are energized by 11.6 VDC with a maximum supply of 500 mA, and pulses as wide as 100 ms can be captured without data loss. During power-up, the logic accepts an inrush of 4 A, and position latches based on TTL channels can be sampled to 400 kHz for high-speed registration tasks.

For functional safety, the controller receives 24 VDC through a shielded D-Sub 9 female terminal reserved for the safe I/O group. Two logic inputs each draw 3 mA, and a pair of semiconductor outputs delivers up to 0.5 A for status lamps or valve solenoids. A relay contact within the safe circuitry can switch machine-enable lines carrying 1 A. Because the safety supply is separated from the base logic, a field-wired emergency stop can remove power to actuators without interrupting bus communication. This architecture lets the controller satisfy stop category 0 requests while keeping diagnostics active during safety-related shutdowns.
