Product Description:

The CSH01.2C-PB-EN2-NNN-CCD-S1-S-NN-FW is a control section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on a power section inside IndraDrive platforms, it performs axis regulation, network interfacing, and machine-safety supervision for automated handling, packaging, and machining lines. The module provides the computing layer that interprets motion commands from the plant PLC, closes the velocity and position loops in real time, and passes drive status back to supervisory software, thereby forming the central coordination element of a servo drive channel.

Its electronics draw only 8.5 W from the internal 24 V bus, minimizing cabinet heat. Two voltage-mode analog outputs sustain loads down to 5 kΩ, and each increment is resolved at 19.5 mV/inc so fine torque or speed references can be delivered to external amplifiers. Primary fieldbus communication is handled through PROFIBUS-DP, accessed with a D-Sub 9-pin female connector for straightforward daisy-chain wiring. When the controller exchanges data with peer drives it operates as a network Master and relies on the IEEE 802.3 Ethernet standard, allowing high-speed cross-communication for electronic gearing and coordinated motion profiles.

The section sources up to 1000 mA on its high-side digital outputs, enough to switch brakes or contactors without auxiliary relays. Encoder feedback arrives over the EnDat 2.1 / 1 Vpp / 5 V TTL port; the board supplies the sensors with 5.0 V at 350 mA to maintain reliable signal levels. A pluggable relay rated at 24 V DC / 1 A provides galvanically isolated status signaling. Functional safety is integrated through Safety Technology I/O, with input circuits rated for 24 V at 3 mA and outputs limited to 24 V at 0.5 A, allowing the controller to execute STO or enable sequences inside the drive cabinet.
