Product Description:
The CSH01.1C-NN-ENS-MEM-MD1-L2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In a drive cabinet, this module forms the interface between higher-level motion commands and the power section that energizes the motor. By combining fast signal conditioning with integrated safety logic, the unit manages positioning, velocity, and torque loops in packaging lines, material-handling cells, and similar industrial automation tasks. It processes command and feedback data locally so the associated drive can respond quickly to changes in load and motion demand.
An internal A/D converter operates at 12-bit resolution, giving the controller sufficient granularity to read feedback values without excessive quantization error. Core electronics draw only 7.5 W, so cabinet thermal load stays low during continuous duty. Differential encoder signals pass through a 120-ohm termination, minimizing reflections on long feedback cables, while the sensor can draw up to 500 mA from the built-in rail. That regulated supply is held at 11.6 V to match most TTL-compatible encoders. This arrangement helps preserve signal quality when encoder wiring is routed through a crowded cabinet. Eight MD1 digital outputs switch field devices such as contactors and relays, and each MEM channel can source 20 mA to external counters or HMI indicators.
During power-up, the section tolerates an inrush of 4 A without nuisance tripping, and its watchdog can capture pulses as short as 100 ms for coordination with external safety chains. The unit provides 12 MD1 digital inputs, permitting direct connection of limit switches or light-curtain signals, while the MEM diagnostic port streams position data at rates up to 1 MHz. That input count supports direct integration of machine permissives and protective devices without separate interface hardware. The Safe Torque Off function removes drive power through dual STO circuits, with acknowledgment contacts rated at 24 V / 1 A and control signals accepted at 24 V / 3 mA.
