Product Description:

The CSH01.1C-NN-ENS-EN1-MD1-NN-S-NN-FW is a motion control module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed as a compact drive logic board, it controls a single motor axis and transfers field data between actuators, encoders, and supervisory PLCs. In an IndraDrive system, the card governs torque loops, interprets serial diagnostic data, and provides the timing base for synchronized positioning in automated machinery.

Two differential analog input channels accept reference values with a resolution of 1.23 mV/inc, captured by a 12-bit converter for fine setpoint granularity. Outgoing analog commands are generated at 19.5 mV/inc through an 8-bit output stage for legacy voltage-controlled devices. The controller is rated for single-axis operation, so scale, filter, and watchdog routines are dedicated to one motor channel, which helps minimize internal latency. The MD1 option card adds 12 digital inputs and 8 digital outputs that use transistor switching for fast state changes in interlocks, limit switches, and field signaling. An RS232 service interface supports cable runs up to 15 m, allowing parameter access from a cabinet door without degrading signal integrity.

For electromechanical integration, the EN1 path supplies 8 V excitation to MKD, MKE, or MHD motor feedback, while the ENS channel delivers 12 V to IndraDyn S multi-turn encoders. The transistor outputs can sink or source currents up to 0.5 A, and the board’s logic section draws only 1 W, easing power-supply sizing inside tight panels. Data exchange through that service port occurs at 115 kBaud, which is adequate for complete parameter uploads. Motor and encoder lines are managed by pluggable terminals, and the digital logic is consolidated on one card. This layout supports deterministic signal flow and fault diagnostics for cyclic positioning profiles without external breakout hardware.
