Product Description:
The CSH01.1C-SE-EN1-NNN-MEM-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive rack, it supervises one axis and executes position, velocity, and torque loops used in machining, handling, and packaging cells. The unit bridges the PLC layer and the power stage, translating fieldbus telegrams into real-time PWM commands for the connected servo or spindle motor.
The controller draws a base idle power of 7.5 W, and when the external logic rail supplies 24 V DC, its inrush current is limited to 4 A to avoid tripping upstream fuses. Two differential analog channels accept process variables through an input resistance of 160 kΩ, ensuring negligible loading on field sensors. Deterministic motion telegrams are exchanged over Sercos II, giving cycle times compatible with multi-axis interpolation. Boolean inputs are recognized as ON once they exceed 15 V, and each transistor output can source up to 500 mA for small relays or status lamps. An 8-bit digital-to-analog converter generates reference voltages for external regulators, while the EN1 header offers an isolated 8 V feed for encoder electronics. Internal circuitry contains no integrated safety technology, so emergency stop functions must be implemented elsewhere in the machine.
For higher-bandwidth applications, the MEM channel can produce reference bursts at 1 MHz, and pulse shaping is supported up to a maximum width of 100 ms to synchronize slower secondary axes. Service access is provided through a 100Base-TX engineering port, while an auxiliary serial channel runs at 115 kBaud when fieldbus access is unavailable. The controller reproduces absolute or incremental encoder signals and exchanges position data with motor feedback transducers on MHD or MKD machines.
