Product Description:

The CSH01.1C-ET-ENS-EN2-MD1-S2-S-NN-FW plug-in card is a controller section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive inverter racks, it supplies the real-time logic that aligns motor torque, speed, and position with machine commands in industrial automation. Its purpose is to interpret encoder feedback, apply programmed motion profiles, and forward status data to PLC or SCADA layers through its integrated Ethernet core. The card also handles drive-based safety functions so axis shutdown can occur without an external relay.

During operation, the card draws only 7.5 W of base power, yet it tolerates startup surges up to 4 A while charging its internal capacitance. The secondary encoder port supplies 350 mA at 5 V; with that supply, the feedback line may extend to 50 m when remote compensation conductors are omitted, or to 75 m when sense wires are present. This EN2 channel accepts EnDat 2.1, 1 Vpp, and 5 V TTL formats, while the primary port handles IndraDyn or HIPERFACE signals. A maximum watchdog pulse width of 100 ms is enforced so stale encoder frames do not propagate into the control loop. Communication with higher-level networks relies on the Multi-Ethernet interface, and RS-232 remains available for service consoles.

Local field wiring attaches to the MD1 terminal set, which provides 12 opto-isolated digital inputs and 8 sourcing digital outputs for limit switches, probes, and drive-ready contacts. For risk-rated functions, the board monitors a safety input line at 24 V / 3 mA and can switch actuators through a 24 V, 0.5 A safety output. All protective functions are handled by the certified Safe Motion package, so permitted velocity, standstill, and shutdown states are enforced internally without delaying the Profinet or Sercos telegram cycle.
