Product Description:
Bosch Rexroth Indramat manufactures the CSH01.1C-NN-ENS-EN2-MA1-NN-S-NN-FW as part of the CSH Advanced Controllers series. The slice is an automation controller that plugs beside power modules in an IndraDrive rack, translating motor-mounted encoder signals, analog feedback, relay contacts, and serial commands into drive-ready data. Within an automated cell, it links servo axes to supervisory PLC logic, allowing deterministic motion sequencing, alarm handling, and parameter adjustment without requiring a separate processor.
The controller’s digital output channel is rated for 24 V / 0.5 A, so it can actuate opto-coupled relays or indicator lamps directly from the drive chassis. Two analog outputs deliver up to 10 mA each and remain stable with loads down to 1 kΩ. Conversion resolution of 12-bit is used for both voltage and current modes, enabling fine speed or pressure references. An RS-232 maintenance port supports transfer rates of up to 115 kBaud, allowing serial communication for diagnostics and trace data logging without removing the card. Complementing those outputs, the MA1 block also supplies two analog input channels for sensor feedback that use the same converter accuracy.
Two encoder supply rails are provided to match different transducer types. The ENS line furnishes 500 mA at a stabilized 12 V for SinCos or TTL encoders, while the EN2 rail offers 350 mA at 5 V for low-power Hiperface variants. By using current-limited sources for each interface, the card helps prevent brownouts when long cable runs increase power demand. A dry relay rated at DC 24 V / 1 A can be mapped to controller events, allowing hardwired fault indication or motor contactor release. These supply, feedback, and relay functions support peripheral sensing and signaling without external breakout boards.
