Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-PL-ENS-EN2-MD2-S1-S-NN-FW for the CSH Advanced Controllers series. The unit acts as a motion-control master that sequences drives and peripheral I/O across machine zones, using onboard option slots to support feedback, safety, and fieldbus functions. Within an automation panel, it coordinates axis commands, digital diagnostics, and safety interlocks so actuators follow the real-time trajectory required by the higher-level PLC. This arrangement allows one control platform to manage synchronized motion and related machine responses from a central location.

At idle, the controller draws only 7.5 W, but a startup surge of 4 A must be supplied by the cabinet power supply. Command data reaches the processor through a Parallel Interface, and the base board offers 16 DI / 16 DO lines for direct field wiring, while the MD2 module adds a separate I/O block to expand the available signals. Output timing is adjusted with a 100 ms pulse-width parameter so actuators receive consistent strobes. The ENS converter resolves position feedback with 12 bit precision, operates from an 11.6 V rail, and can supply sensor power. A 24 V supply on the MD2 slot powers SSI encoders, while separate safe I/O terminals are rated at 24 V / 3 mA for inputs and 24 V / 0.5 A for outputs, allowing use in Category 3 safety chains.

The EN2 interface supports incremental encoders. It maintains a load resistance of 35 Ω and is powered by 5.0 V, which helps keep signal transmission stable over longer cable runs. For higher-resolution feedback, the ENS port accepts TTL inputs up to 400 kHz, allowing the controller to track rapid spindle or gantry motion without losing counts. These encoder interfaces allow the controller to process fast feedback signals while also handling brakes, contactors, and other connected field devices through its onboard I/O.
