Product Description:

The CSH01.2C-NN-EN2-EN2-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It acts as the central motion processor inside IndraDrive systems. The unit handles axis coordination, feedback evaluation, and field-level communication for industrial automation cells such as packaging lines, material-handling gantries, and other synchronized machine platforms where multiple functions must operate together in a controlled sequence.

During standby the unit draws only 8.5 W, which minimizes panel heat and eases power-supply sizing. All logic circuits are fed from a separate DC 24 V supply so the controller can remain active while the main drive bus is de-energized. Network traffic moves through a SERCOS III Master interface, allowing deterministic exchange of setpoints and status with up to 32 slave drives. For position and velocity feedback, it provides 2 x EnDat 2.1 / 1 Vpp / 5 V TTL channels, letting the system use absolute optical encoders together with incremental sine-cosine or TTL devices on the same card. When control voltage is first applied, the input stage can momentarily draw 4 A, so the supply path must tolerate that short peak without nuisance trips. Programmable output pulses that supervise safety functions are limited to a maximum width of 100 ms to help prevent unintended latching of external relays.

The I/O header can source up to 1.1 A in total, supplying sensors or light loads without an extra supply module. Diagnostics are performed through a maintenance port that uses the RS232 protocol, and the physical connection is made through a keyed MiniDIN, 8-Pin socket for quick cable exchange. The card also carries one analog input, two analog outputs, and four combined digital channels, which supports straightforward integration of potentiometer references, torque monitor signals, and limit switches alongside the fieldbus network while keeping local signal wiring on the control section.
