Product Description:

The CSH01.1C-NN-ENS-EN1-MA1-NN-S-NN-FW is a controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in drive cabinets, it provides signal conditioning and feedback handling so that IndraDrive power sections can execute precise motion profiles in automated machinery. The unit adds analog and encoder functions to axis groups, translating field-level measurement data into drive commands without a separate master communication slot, which simplifies layouts where a dedicated bus controller is already present.

The analog front end accepts a symmetrical input span of ±10 V. This voltage window lets the drive interpret proportional process signals from transducers or external PLC cards. Input impedance is a high 160 kΩ, so sensors see only a minimal load and can maintain accuracy over long cable runs. Conversion on the MA1 channel occurs at 12-bit resolution, giving 4096 discrete steps for speed or torque references. For resolver feedback, the En1 channel delivers a carrier of 18.2 Vpp, and the Ens rails supply encoders with a regulated 11.6 V, with both values matched to Bosch Rexroth feedback standards. When the drive must retransmit a process signal, the base analog output is a buffered 5 V level that matches typical motion-control reference inputs.

The housing is only 49.5 mm wide, 241 mm tall, and 103 mm deep, so multiple controllers can be lined up on DIN rails with limited panel space. Relay contacts inside the card switch up to 1 A at 24 V DC for status or brake circuits, and an X10 analog I/O extension slot allows future channel expansion. Feedback versatility is covered by an X4 interface that recognizes IndraDyn, Hiperface, 1 Vpp, or TTL signals, while X8 accepts HSF or RSF encoders. No integrated safety option is present, so external safety relays or PLC-based safety control can be used separately.
