Product Description:

The CSH01.1C-S3-ENS-EN1-NNN-S2-S-NN-FW controller section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed as a plug-in module for IndraDrive power units, it supervises axis position, velocity, and safety interlocks inside automated machinery. By integrating Ethernet communication, dual-channel encoder evaluation, and Safe Motion technology, the unit bridges plant-level PLC commands to drive-level current loops and supports coordinated multi-axis operation in conveyor, packaging, and machining systems. Its compact form factor allows placement directly on the power stack, which helps reduce cabinet space and wiring.

The card's electrical footprint is limited to a base consumption of 7.5 W, so heat generation inside the enclosure remains modest. For control-network access, it uses an RJ-45 8-pin connector that follows the IEEE 802.3 standard and provides 100 Mbit Ethernet communication for diagnostics. Real-time axis commands are exchanged over the optical ring used by SERCOS III. During initial power-on, the capacitors draw an inrush of 4 A, after which nominal currents fall well under the supply limits of the associated power section. A 100 ms maximum pulse width is accepted on discrete inputs, and an RS232 serial interface provides service access.

Feedback handling is organized through two D-Sub 15 female connectors, with EN1 for the primary encoder and ENS for the secondary channel. The ENS port supplies up to 11.6 V at 500 mA for TTL or SinCos transducers, while the HSF channel provides 8 V at 250 mA to bidirectional hybrid sensors. Resolver devices can be driven with a carrier of 18.2 Vpp at a fixed excitation frequency of 4 kHz, allowing the drive to support legacy motors that lack digital feedback. Safe Motion circuitry monitors these inputs continuously to apply torque cutoff within the allowed pulse-width window.
