Product Description:

Bosch Rexroth Indramat's CSH01.1C-SE-NNN-NNN-NNN-L1-S-NN-FW is a plug-in controller card from the CSH Advanced Controllers series. It sits between drive amplifiers and supervisory PLCs, executing position, velocity, and diagnostic routines for a single axis. By combining analog, digital, communication, and machine safety interfaces on one board, the card streamlines motion-control wiring in automated assembly lines, packaging equipment, and handling systems. Acting as the command layer that translates fieldbus telegrams into precise setpoints, it helps coordinate motor movement and process feedback in real time.

The analog front end accepts a differential input of ±10 V, allowing speed or torque references from external signal conditioners. Each increment on this channel is resolved at 1.23 mV/inc, so small setpoint variations are digitized accurately for closed-loop correction. Command values can also be generated on the board itself, and its output spans 0 to 5 V with a granularity of 19.5 mV/inc. All cyclic process data are transferred over the SERCOS II control bus, which supports deterministic 62.5 µs telegram timing. A discrete input switches to logic on at 15 V, providing a clear threshold for limit switches or sensor lines.

Further interaction with service tools is handled through an RS-232 maintenance port that supports cable lengths up to 15 m and uses an 8-pin Mini-DIN plug. Its throughput peaks at 115 kBaud for parameter transfers. Field devices such as relays or indicator lamps can be driven directly by the card through a 24 V / 0.5 A digital output and a separate relay contact. The safety logic monitors an input signal of 24 V / 3 mA through a D-Sub 9-pin female connector, and the acknowledgment line uses DC 24 V / 1 A. The dedicated safety function, starting lockout, prevents unintended energizing of connected axes until all interlocks are satisfied.
