Product Description:
The CSH01.1C-NN-EN2-MEM-MA1-NN-S-NN-FW is a modular drive controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, this module handles axis regulation, feedback processing, and local I/O tasks within automated machinery. Because it is dedicated to motion control, it accepts encoder feedback, passes command data to the power stage, and supplies low-level signals required for coordinated positioning, speed regulation, and process monitoring on assembly lines and material-handling systems.
On the digital side, the board can switch external devices with a rated sink current of 0.5 A per channel, supporting relays or light-indicator circuits directly. Position feedback arrives through a multi-protocol interface that supports EnDat 2.1 / 1 Vpp / 5 V TTL, allowing the same slot to read either absolute or incremental encoders without extra hardware. The integrated MA1 option card provides two differential analog inputs that accept signals in the range of ±10 V, which is standard for speed or torque reference loops from a PLC. Complementing those inputs, each analog output can source up to 10 mA, so it can drive servo valves or transmit diagnostic values to chart recorders. For parameterization, an RS-232 port communicates at 115 kBaud with PC-based tools, and the control-communication slot is left unequipped so a fieldbus module can be added as needed.
To mirror motion data toward legacy counters, the MEM extension produces absolute and incremental encoder copies while still forwarding the original feedback to the drive. The line drivers on that channel can deliver up to 20 mA per output at a maximum toggling rate of 1 MHz, which is adequate for high-resolution interpolation on external controllers. An internal supply rail of 5 V is available on the connector, so attached transducers can be powered without a separate regulator. External counters can use these duplicated position signals without interrupting the original feedback path.
