Product Description:

The CSH01.1C-PB-ENS-EN1-MD2-NN-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on an IndraDrive power section, it supplies the logic required to execute drive commands, supervise feedback channels, and connect to plant networks. This arrangement keeps the control electronics separate from the power stage while allowing the drive to match different axis and network requirements. In industrial automation, it serves as the command layer that links servo axes to higher-level PLCs for synchronized speed, torque, and position regulation. The housing measures 49.5 mm in width, 241 mm in height, and 103 mm in depth, allowing high-density mounting inside compact electrical enclosures.

Field communication is centered on the integrated PROFIBUS master port, which lets the controller exchange cyclic data with distributed I/O and other drives over the 12 Mbit network. The analog input stage presents 160 kΩ of impedance so connected sensors place negligible load on their source circuits. When the controller generates an analog reference, the channel supplies 5 V, 1 mA, a level compatible with standard control cards. Discrete actuator commands are handled through transistor outputs rated at 24 VDC, 0.5 A, providing enough current for contactors or indicator lamps. For point-to-point diagnostics or parameter transfer, an onboard RS232 serial interface is available.

Beyond those base functions, the module includes the Option 3 slot fitted with digital I/O with an SSI encoder, letting a single-turn or multi-turn sensor stream synchronous position data directly to the control loop. Safety relays are not supervised internally, yet a general-purpose contact rated at 24 V, 1 A can forward ready or fault status to external interlocks. High-speed edge capture uses the probe input that tolerates 24 V, 3 mA, 1 μs, allowing precise time stamping of reference marks. All auxiliary electronics draw up to 1.1 A max from the shared I/O supply, so cabinet power budgeting can be calculated accordingly.
