Product Description:
The CSH01.1C-NN-ENS-EN2-MEM-S2-S-NN-FW is an axis control card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within a drive stack, it executes position, velocity, and torque loops for IndraDrive servo axes while exchanging status with higher-level PLCs. By hosting the control logic and option modules, the card provides the computational core that coordinates motor feedback, field signals, and safety functions in industrial automation cells.
It draws a base idle load of 7.5 W and accepts a momentary inrush of 4 A, with that surge limited to 100 ms by integrated capacitive damping so the upstream supply does not require oversizing. When operating, its analog output stage resolves commands in steps of 19.5 mV/inc, allowing fine current reference generation for the power section. The card is shipped without control-bus communication hardware, so SERCOS or EtherNet modules are added externally. An emulation module is present and does not require a separate power source. For feedback, it offers a primary interface of IndraDyn/Hiperface plus a secondary channel that supports EnDat 2.1, 1 Vpp, or 5 V TTL encoders, each powered through a dedicated low-power rail. The RS-232 diagnostic port can be cabled up to 15 m for bench setup.
The safety segment of the card is implemented through the Safe Motion module, allowing certified STO, SOS, and SS1 functions without external relays. Its dual-channel outputs can switch logic loads up to 1.6 A and provide a separate 24 V / 0.5 A line for valve or lamp actuation. General-purpose relay contacts are rated for DC 24 V at 1 A, offering galvanic isolation for field alarms. The encoder connector carries a regulated 5.0 V supply and supports sense-line compensation over cables as long as 75 m, which helps maintain precise feedback on moving-axis gantries. Because the base energy demand is modest, the module fits into fanless cabinets. The absence of built-in fieldbus hardware leaves space for added communication modules without disturbing established safety wiring.
