Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-PL-EN1-NNN-NNN-NN-S-NN-FW as part of the CSH Advanced Controllers series. The unit is a single-axis control section that plugs into an IndraDrive power module and executes position, velocity, and torque loops for servo axes in automated machinery. By combining analog, digital, and serial channels on one card, it links sensors, encoders, and higher-level PLCs to the drive so motion commands and feedback data move between field devices and the controller in real time.

The analog input stage accepts a span of ±10 V, which allows full-scale reference signals from speed potentiometers or external motion cards without extra scaling. A high input impedance of 160 kΩ minimizes loading so upstream sources are not pulled down. For actuator control, an analog output delivers 5 V at 1 mA, providing a low-power reference for external amplifiers. Digital command lines are rated at 24 V DC at 3 mA on the input side, which suits standard sensor wiring, while the output transistors can switch loads up to 24 V DC at 0.5 A, enough for contactors or signal lamps. The EN1 processor core draws only 6 W, keeping cabinet heat dissipation low even in dense multi-axis racks. All cyclic data exchange with a host PLC passes through the X15 parallel connector, and resolver or high-speed feedback is accepted through the 15-pin encoder port.

Sixteen discrete lines are mapped in both directions, giving 16 inputs and 16 outputs for fast bit-level handshaking between the drive and peripheral automation. When setup or diagnostics are needed, an asynchronous link runs up to 115 kBaud over the onboard RS-232 interface without removing the card. A dedicated 1 W supply for the PL interface separates logic from power electronics, and the 4 kHz resolver carrier with an 18.2 Vpp excitation maintains accurate shaft position feedback for closed-loop operation.
