Product Description:

The CSH01.1C-PB-NNN-NNN-NNN-L2-S-XP-FW is a control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in modular IndraDrive platforms, it coordinates motion axes while handling local I/O and network traffic. The unit communicates over PROFIBUS-DP to exchange cyclic data with PLCs and supervisory systems, and it is delivered with a standard control panel for local parameter access. In automated lines, this controller supplies the real-time commands that synchronize drives, sensors, and safety circuits. It also acts as the interface between higher-level machine control and the connected drive hardware, keeping command processing and signal exchange in one module.

The controller’s input layer provides one analog channel, and its impedance of 160 kΩ prevents loading sensitive process signals. Two analog outputs are available, each with a resolution of 19.5 mV per increment for drive-speed or valve setpoints. Four combined digital I/Os and a pair of probe inputs support position latching aligned to a bus speed of 12 MBaud, allowing deterministic interaction with higher-level motion tasks. Internal electronics draw a base power of 7.5 W, yet they must withstand an inrush of 4 A when the DC bus is energized. The section accepts event markers as short as 100 ms and forwards them over PROFIBUS, while the single 15-pin panel connection maintains the standard operator interface.

Edge-triggered machine functions connect directly because each digital input reaches its on state at 15 V, and high-side drivers can source up to 0.5 A for contactor coils or indicator lamps. The integrated Safe Torque Off channel disconnects gate signals to the power stage without relying on software, meeting category-oriented shutdown requirements. For diagnostic access, an auxiliary RS232 interface offers a point-to-point connection that is independent of the fieldbus. That separate port allows direct access to the control section even when the network is unavailable or isolated from the rest of the machine.
