Product Description:

The CSH01.1C-SE-ENS-EN2-MD1-L1-S-K1-FW is a motion control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, the unit supplies the command layer that synchronizes servo loops, handles fieldbus traffic, and cooperates with integrated safety logic. By routing position and speed feedback from primary and secondary encoder ports, it governs electric drives used in conveyors, pick-and-place gantries, and high-speed packaging machines.

This controller accepts analog reference signals against an input impedance of 160 kΩ, so connected transducers are not significantly loaded. Its digital-to-analog converter moves in steps of 19.5 mV/inc, providing fine voltage resolution for torque or speed setpoints. Command exchange with the drive stack uses the deterministic SERCOS II interface, ensuring synchronized updates within every communication cycle. The onboard digital output stage can source up to 500 mA in total, allowing it to drive contactors or status lamps without external relays. A built-in Ethernet service port follows the 100Base-TX standard, providing direct access to parameter files and diagnostics. Diagnostic data appear on a single-line display, and the module is designed for one axis, making it suitable for dedicated point-to-point positioning tasks. Feedback compatibility covers IndraDyn or HIPERFACE encoders at 1 Vpp on the primary channel and EnDat 2.1, 1 Vpp, or 5 V TTL on the secondary channel.

The MD1 expansion provides 12 inputs for limit switches or sensors and 8 outputs for actuator commands, enabling local signal handling without extra I/O cards. A built-in safety layer implements Starting Lockout, which blocks unintended energizing of the power stage until all permissive sources are valid. The primary encoder port supplies a stabilized 12 V feed, while the secondary port offers 5 V for EnDat sensors, allowing mixed incremental and absolute feedback topologies. Additional connectivity includes an RS232 serial port for legacy service tools and an engineering Ethernet interface for modern workstations.
