Product Description:
The CSH01.1C-SE-EN2-EN2-MEM-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for integration within the CSH Advanced Controllers series. It plugs into an IndraDrive base unit and provides axis-coordinated motion commands to servo drives in automated machinery. By combining high-speed encoder feedback with fieldbus communication, the module performs real-time positioning and velocity regulation in packaging lines, printing presses, and handling systems. Its role inside the drive is to process command data, feedback signals, and interface status so connected axes respond predictably during continuous operation.
This version communicates on SERCOS II and supports a bus data rate of 16 MBaud, allowing tight synchronization between the controller and multiple drives. The minimum cyclic period is 250 µs, so setpoint updates and status words can be exchanged four thousand times per second. A dedicated MEM channel delivers position-compare signals at up to 1 MHz, and the pulse-width-modulated outputs can switch as fast as 16 kHz for precision current control. Two EnDat 2.1 / 1 Vpp / 5 V TTL inputs accept absolute or incremental encoders for dual-loop feedback. One differential analog input and two differential analog outputs let the control section exchange process signals with external equipment, while the lack of integrated safety circuitry means emergency-stop handling must be provided by external devices.
The single analog input presents an impedance of 160 kΩ, which minimizes loading on external sensors. For diagnostics or service access, a serial port is available with a maximum transfer speed of 115 kBaud, and it operates independently of the SERCOS link. Each encoder socket supplies the EnDat sensors with 5 V, eliminating the need for separate power feeds. A form-C relay provides one normally open contact for drive-ready signaling to higher-level controllers. The analog and encoder interfaces allow the control section to exchange motion-related feedback and reference signals without adding separate interface modules.
