Product Description:

The CSH01.1C-CO-EN2-EN2-NNN-NN-S-NN-FW controller module is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Serving as the control core for IndraDrive drive stacks, it converts fieldbus commands into real-time axis instructions for use in conveyors, packaging lines, and machining centers. The unit occupies the control slot of a drive and supervises feedback signals, scheduling motion profiles so that mechanical components follow the required speed, torque, or position sequence inside an automated installation.

Analog processing begins with an input resistance of 160 kOhm, a high impedance that minimizes loading on external sensors. Each input step is resolved at 1.23 mV/inc, allowing fine differentiation of low-level signals before the control algorithms act. Outgoing commands pass through a single 1 mA analog channel whose granularity is 19.5 mV/inc, which is adequate for proportional valve drives and reference potentiometers. Digital resources include sink outputs that can supply 500 mA per channel, and their circuitry is protected against initial power-up surges by an inrush limit of 4 A. Two identical encoder ports, EnDat 2.1, 1 Vpp, and 5 V TTL, let the controller read absolute or incremental feedback without additional interface cards.

Overall consumption is held to 7.5 W, so the unit adds little heat to crowded cabinets while still delivering an output group capacity of 1000 mA for simultaneously driven relays or indicator lamps. Each output can absorb up to 400 mJ of inductive energy, and pulse commands may extend to 100 ms to match pneumatic valve dwell times. Application data is stored on a MultiMediaCard, and configuration can be adjusted locally through an RS232 service port. Network control is carried over CANopen or DeviceNet, and no integrated safety technology is included.
