Product Description:
The CSH01.1C-NN-EN1-EN2-MEM-NN-S-NN-FW motion-logic control card is produced by Bosch Rexroth Indramat for use in multi-axis drive assemblies that belong to the CSH Advanced Controllers series. Installed in a Rexroth power section, the card executes axis interpolation and manages I/O exchange between the drive and a host PLC or fieldbus. Within an automation cell it coordinates position, speed, and diagnostic data so servo drives follow commanded trajectories without external add-on processors.
This controller offers two differential analog inputs that accept a span of ±10 V; a high input resistance of 160 kΩ minimizes loading on upstream sensors. Each conversion step is quantified at 1.23 mV/inc, enabling fine reference scaling for torque or velocity loops. The board also carries a single analog output that delivers a full-scale signal of +5 V; with an output granularity of 19.5 mV/inc, it can generate precise trim commands for external converters or actuators. This resolution supports closed-loop analog channels and helps with external filter selection.
Complementing the analog sections, the card integrates digital resources for fast edge capture, high-speed pulse generation, and safe relay switching. A memory-based pulse generator reaches a maximum output frequency of 1 MHz for stepper or pulse-direction interfaces, while the eight digital outputs can source up to 500 mA each, limited to an aggregate 1000 mA per group. For precise touch-probe applications the circuitry timestamps rising or falling edges within 1 µs of actual occurrence and accepts pulses down to 4 µs wide. A Form-C relay routes field power up to 1 A at 30 VDC to interlock brakes or contactors. Additional channels include a 4 kHz resolver input energized by an 18.2 Vpp carrier, a secondary encoder port supplied with 5 VDC, and logic inputs that switch reliably once the line exceeds 15 V. The controller can process high-resolution analog feedback alongside deterministic digital events during coordinated axis control.
