Product Description:
Bosch Rexroth Indramat designs the CSH01.1C-SE-ENS-MEM-MA1-S1-S-NN-FW as part of its CSH Advanced Controllers series. The unit is a compact control section that inserts into an IndraDrive amplifier and executes closed-loop motion, fieldbus routing, and machine safety functions in one module. By hosting both encoder evaluation logic and user-programmable control functions, it can synchronize multiple servo axes, monitor position feedback, and react to safety inputs with millisecond latency. The controller streamlines cabinet layouts where distributed servo drives must be linked to a central PLC over fiber optics.
The on-board A/D converter resolves analog feedback at 12-bit depth, while the MA1 module offers two differential inputs and two voltage outputs for process signals. Network traffic moves over the SERCOS II optical ring, and this control section sustains telegram rates as high as 16 MBaud, ensuring cycle-synchronous data exchange between the drive and master. For simulated encoder feedback, the emulation port can toggle up to 1 MHz, and physical encoder signals are tracked up to 500 kHz without aliasing. These timing capabilities allow the controller to supervise rapid spindle or pick-and-place axes without losing position coherence.
The encoder interface presents an input impedance of 120 ohms, is powered by an internal supply of 11.6 VDC, and can source up to 500 mA to absolute or incremental transducers, removing the need for an external line driver. TTL reference channels are accepted up to 400 kHz, and SERCOS status is monitored through a dedicated diagnostic LED strip. A D-Sub 9 female connector carries the integrated safety circuit, and its solid-state outputs are rated at 24 V / 0.5 A, enabling direct actuation of contactors that disconnect mechanical power when a fault is detected.
