Product Description:

The CSH01.1C-SE-ENS-NNN-MA1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power base, it executes axis calculations, manages encoder feedback, and distributes real-time setpoints so conveyor lines, presses, or pick-and-place machines maintain synchronized motion. By concentrating motion logic at the drive level, the unit reduces the processing load on the central PLC and shortens cycle time in demanding automation cells. It is suited to coordinated multi-axis duties where interpolation, registration, and fast setpoint updates must stay inside the drive system.

SERCOS II is the primary real-time network, and the fiber coupling is tightened to 0.6 Nm to secure the optical ring without damaging the ferrule. A service RS-232 port transfers serial data at up to 115 kBaud over cable runs of 15 m, providing a direct local interface when the fieldbus is unavailable. Position feedback arrives through a D-Sub 15-pin female connector that also supplies the transducer with 12 V. The dedicated feedback connector keeps encoder wiring separate from the network and service links, which helps preserve signal clarity. Safe Torque Off removes drive gate signals as soon as the safety loop opens, which prevents unintended motor rotation and supports machine stop functions that rely on the drive electronics.

The MA1 analog module provides two differential inputs with an impedance of 1000 kΩ and a resolution of 5 mV/Inc, allowing accurate evaluation of load cells, potentiometers, and similar reference devices. Two analog outputs can source 10 mA into loads down to 1 kΩ, so the controller can send stable reference values to external amplifiers and related control hardware. An additional onboard input path presents 160 kΩ of resistance for auxiliary sensors, and two probe inputs latch position events in hardware for precise registration marks. Because the probe channels capture events in hardware, registration tasks do not depend on normal PLC scan timing. These signal paths support local current, pressure, or speed-loop tasks while leaving higher-level sequence control to the main machine controller.
