Product Description:

The CSH01.2C-PL-ENS-NNN-CCD-S1-S-NN-FW is a single-axis control section developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It functions as the central processing element that coordinates drive parameters, fieldbus signaling, and safety tasks within an IndraDrive modular drive stack. In industrial automation, its purpose is to execute motion algorithms and pass real-time setpoints to connected power sections so servo motors follow commanded profiles with deterministic timing. This arrangement keeps command processing, communication handling, and safety-related coordination in one module, which supports orderly interaction between the control section and the attached power electronics.

During operation, the control section draws only 8.5 W, a low internal consumption that simplifies cabinet thermal calculations. Command and diagnostic data reach the unit through a parallel interface, allowing simultaneous transfer of multiple bits without serial framing overhead. Sixteen digital channels are reserved for fast input capture, so the hardware accepts 16 parallel inputs for rapid sensing of limit switches or probes. For service communication, the RS-232 port can stream status words at up to 115 kBaud, while emergency shutdown or torque-off commands can be forwarded to external contactors through a safety output rated at 24 V / 0.5 A for electrically isolated actuation of fail-safe relays.

In coordinated drive groups, the CSH01.2C section is configured as the network master, so it distributes clock and interpolation data to subordinate axes. Position feedback from machines is decoded by the built-in encoder evaluation circuit, which supplies the transducer with 11.6 V and up to 500 mA; this dedicated power rail prevents loading the logic supply during high-speed encoder cycles. When a protective device requests a safe state, it can assert a safety input level of 24 V / 3 mA, triggering the Safety Technology I/O layer to inhibit pulse generation without affecting non-safety data paths. This separation helps safety signaling act quickly while normal communication remains available for status handling and controlled recovery.
