Product Description:
Bosch Rexroth Indramat manufactures the CSH01.1C-NN-ENS-NNN-MEM-S2-S-NN-FW control section as a component of the CSH Advanced Controllers series. The unit serves as the processing node inside IndraDrive systems, translating command variables and feedback data between a higher-level PLC and the drive inverter. By combining analog, digital, and encoder signal handling on a single board, the controller coordinates motion sequences and supervises system status during continuous industrial duty.
Its analog front end supports precise reference tracking; an input impedance of 160 kΩ minimizes loading on sensors, while a conversion granularity of 1.23 mV/inc allows tight scaling of speed or torque setpoints. On the output side, each channel can source up to 1 mA, with a voltage step size of 19.5 mV/inc, so downstream devices receive deterministic levels. For discrete control, transistorized outputs can deliver 500 mA, which is enough to energize solenoid valves or contactor coils. Encoder emulation is provided, and the IndraDyn, Hiperface, 1 Vpp, and TTL interface accepts multiple feedback formats without external converters. No master fieldbus hardware is installed, leaving network selection to extension options.
During power-up, the logic path draws an inrush of 4 A for 100 ms before settling to a continuous demand of 7.5 W, permitting installation in cabinets that share low-voltage supplies. Probe capture is precise; events are latched within 1 µs when the 24 V, 3 mA probe input toggles. The safety layer is certified to Safe Motion (SIL2 / cat. 3 PL d), enabling speed-limited and stop-category monitoring without external safety relays. A form-C relay rated at 24 VDC and 1 A provides galvanic isolation for alarm chains, and the mechanism is specified for 1 × 108 operations, supporting high-cycle production equipment.
