Product Description:

The CSH01.3C-ET-EN1-EN2-CCD-S2-S-NN-FW is a plug-in controller card developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive base, it handles axis control, sensor integration, and real-time network exchange so servo drives can follow reference positions and velocities in industrial automation lines. It provides layered processing between the power electronics and factory-level PLCs by translating feedback from encoders and resolvers while forwarding setpoints across Ethernet networks. The card also handles interpolation, diagnostics, and safety functions that keep motor motion synchronized with machine sequencing.

Its two differential analog inputs present an impedance of 160 kΩ, which limits source loading when velocity or torque commands are supplied from external regulators. The input conversion granularity is 1.23 mV/inc, and the single analog output has a resolution of 19.5 mV/inc for status feedback to supervisory devices. The board draws a base logic power of 8.5 W, and its four semiconductor digital outputs can sink or source up to 500 mA in total for contactors, lamps, or low-power valves. Cross-communication rails inside the drive add 1 W, and the multi-Ethernet interface requires 2.2 W during cyclic data exchange.

During encoder operation, the EnDat, 1 Vpp, and TTL rails can supply 6 W, while the separate resolver/HSF path has the same power allowance and is excluded from the logic overhead. The EN2 expansion socket provides 350 mA for auxiliary boards, and the combined allowance on all outputs is 1000 mA. At startup, the card withstands an inrush of 4 A, and the suppression hardware absorbs 400 mJ from inductive loads. Each digital output can issue pulses of up to 100 ms, and an 8 V HSF rail feeds safe-stop inputs while the front-panel electronics remain within a 1 W limit.
