Product Description:
The CSH01.1C-S3-ENS-MEM-MD1-S2-S-NN-FW is a motion and I/O controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive power sections, it supervises axis drives, reads encoder data, and executes the Safe Motion routine required by modern production lines. By combining communication, analog sensing, and digital field I/O in one compact slot, the module takes the role of a centralized drive controller, reducing the need for an external PLC and shortening machine response times. This arrangement keeps control tasks close to the drive hardware and helps reduce signal path length inside the system.
The controller’s front edge carries one differential analog input that accepts a maximum swing of ±10 V, which allows direct connection to torque or process sensors without scaling. The input circuit presents 160 kΩ of impedance, so source devices experience negligible loading. The module has 1 analog input and 2 analog outputs. Each output can source 1 mA, which is suitable for drive references or diagnostic test points. Absolute position values can also be retransmitted in SSI format, while an internal converter recreates incremental pulse trains for legacy counters. Encoder emulation and selectable IndraDyn, HIPERFACE, 1 Vss, or TTL hardware ports allow different feedback devices to operate on a single axis.
For network traffic, the device uses a shielded port with a RJ-45, 8-pin connector that operates at the Ethernet-based 100Base-TX physical layer. Motion commands and diagnostics are exchanged over the deterministic Sercos III protocol, allowing cycle times below a millisecond when multiple drives are daisy-chained. Encoders powered from a dedicated 12 V rail can be read through the interface, and their positions are monitored by the Safe Motion channel that meets SIL2 / Category 3 PL d. Total controller demand is only 7.5 W, which eases power-supply sizing. The MD1 extension adds twelve digital inputs and eight high-side outputs, so field devices such as light curtains, valves, and contactors can be wired directly.
