Product Description:
The CSH01.1C-SE-EN1-NNN-NNN-L1-S-NN-FW is a single-axis controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit mounts in IndraDrive power sections and governs torque, velocity, and position loops for servo or asynchronous motors. Inside an automation cell, it acts as the command layer that converts machine-level instructions into real-time drive signals. This arrangement lets the power section handle energy conversion while the controller focuses on regulation, feedback processing, and drive-level logic. It also manages motion sequencing, status handling, and communication between the drive and the higher-level control.
It provides one voltage-scaled analog monitor channel that spans 0 to +5 V and uses a 5 kOhm load, with a resolution of 19.5 mV/inc. Deterministic drive coordination is handled over the fiber-optic SERCOS II ring, so axis data can be exchanged with cycle times below 1 ms and synchronized with the rest of the system. For discrete diagnostics, the digital outputs can sink or source up to 500 mA, and a Form-C relay is rated for DC 24 V, 1 A for external switching tasks. The encoder port supplies 8 V to position sensors, and a front-mounted standard control panel provides local parameter access through keys and a display, while safety wiring lands on a D-Sub 9-pin female connector tied to the integrated starting lockout circuit.
The feedback section supports resolver and HSF formats and identifies R0, R1, S0, or M0 code tracks while demodulating carrier signals driven by 18.2 Vpp at 4 kHz. The controller uses that feedback to calculate rotor angle and process position information during operation. A serial maintenance port operating on RS232 provides a direct interface for service communication and diagnostics. A built-in starting lockout function disables pulse enable until the emergency-stop chain is cleared. The feedback circuitry remains electrically isolated from the field wiring, which helps protect low-level sensor signals from external interference.
