Product Description:

The CSH01.1C-S3-EN2-MEM-MA1-NN-S-NN-FW is a controller plug-in produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed as a single-axis command module, it interfaces with a drive inverter to calculate position, velocity, and torque commands for one motor. By integrating fieldbus communication, local encoder evaluation, and configurable I/O, the card streamlines closed-loop motion tasks in conveyors, pick-and-place units, and machine tools. Because it serves as the command layer rather than the power stage, the plug-in focuses on motion computation, signal handling, and network exchange inside the drive system.

It operates from a control supply of 24 V DC and maintains internal logic with only 7.5 W of basic power draw, which helps limit cabinet heat. When the supply is applied, the module tolerates an inrush current of 4 A before stabilizing. Each digital output can source up to 500 mA, while the separate EN2 sensor rail consumes 350 mA to power external encoder electronics. Command data move through a SERCOS III ring that enters the board on an RJ-45 8-pin socket. The encoder interface accepts EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL incremental feedback. Logic-level pulses presented to the MA1 fast-counter section are accepted with widths up to 100 ms, enabling catch-and-compare triggers when required.

For parameter storage and high-speed capture, the MEM channel supports cable runs of 40 m and transfers latch signals at up to 1 MHz without loss of edge fidelity. The MA1 analog front end handles two input channels and two output channels, each resolved to 12 bit, giving suitable granularity for tension or pressure loops. Serial diagnostics are performed over an RS-232 port that reaches 115 kBaud, allowing service commands and parameter access outside the real-time bus. The analog section can also exchange reference and monitoring signals with external sensors and actuators used by the machine.
