Product Description:
The CSH01.1C-SE-ENS-MEM-MD2-L2-S-NN-FW is a single-axis controller card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed in IndraDrive power sections, it provides motion control, I/O handling, and safety supervision for servo axes used in material handling, packaging, and general factory automation. Its purpose is to coordinate drive functions, exchange real-time data with higher-level PLCs, and execute shut-off logic when hazardous motion must be prevented. Because the controller card is installed directly in the drive platform, axis control remains localized within the power section rather than being assigned to a separate motion module.
This card is powered from a control supply of DC 24 V, and its base electronics draw just 7.5 W, which helps limit cabinet heat dissipation. Command and status data are transported through the deterministic SERCOS II fiber ring, while a service port based on RS-232 supports parameter backup. Control communication travels over fiber-optic cables, giving immunity to electromagnetic interference and permitting long cable runs inside large machines. This communication path supports stable real-time exchange between the drive and the machine controller during synchronized motion. An analog monitor channel can source 5 V at 1 mA for external meters, and the encoder section handles both absolute and incremental feedback through a standard evaluation interface.
An inrush limiter restricts startup current to 4 A so the shared 24 V supply remains stable, and output pulses from the MD2 stage are limited to a maximum width of 100 ms for reliable actuator triggering. Field wiring terminates on a 44-pin high-density D-Sub connector that mates directly with ribbon or discrete harnesses, and the digital channels are sampled for high-speed interlocks. Safe Torque Off is implemented in hardware to meet stop category 0 without additional relays, and the safety circuit removes torque-producing energy at the drive level when a stop command is issued. The MD2 mezzanine also adds digital I/O and SSI encoder evaluation for devices that require direct field-level signaling.
