Product Description:
The CSH01.3C-NN-ENS-EN1-CCD-NN-S-NN-FW is a modular control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed on an IndraDrive platform, the module serves as the command processor for servo axes and auxiliary inputs in industrial automation cells. Its role is to translate high-level program instructions into timed motion profiles and coordinated I/O actions. The configuration supports demanding machine tools, packaging equipment, and material-handling systems where deterministic communication and compact drive integration are required.
At the fieldbus layer, cross-communication is handled through SERCOS III, giving the unit deterministic cycle timing and synchronization with other drive sections. Two analog outputs can feed external instrumentation, while its closed-loop current regulation refreshes every 62.5 µs to minimize torque ripple on connected motors. Each digital output channel can source up to 500 mA, and the relay contact is rated for 24 VDC at 1 A, making it suitable for solenoid or contactor actuation. During power-up, the control section draws an inrush of 4 A before settling to a total consumption of 21.5 W. Internally, this logic controls gate commands that support drive switching frequencies without exceeding thermal limits.
Encoder support is split between two isolated supplies: 12 V for IndraDyn or Hiperface transducers and 8 V for legacy MHD, MKD, or MKE feedback units. The primary interface accepts incremental 1 Vpp or digital protocols, while the secondary socket maintains compatibility with resolver-based motors. Engineering access uses an RJ-45 8-pin connector operating on 100Base-TX and permits Ethernet cable runs to 100 m. A separate RS-232 service port is limited to 15 m when low-speed diagnostics are preferred. Pulse patterns generated by the control logic can be switched at up to 16 kHz, allowing the power stage to drive high-speed servo motors without audible carrier noise.
