Product Description:
The CSH01.1C-PB-EN2-EN1-NNN-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in an IndraDrive modular drive stack, this unit executes motion commands, manages feedback channels, and coordinates axis functions across a machine. It serves as the central processor that converts PLC telegrams on the fieldbus into regulated current, velocity, or position profiles for servo inverters used throughout industrial automation cells.
Its field communication relies on PROFIBUS-DP, accessed through a D-Sub 9-pin female connector that isolates the network segment and simplifies daisy-chain wiring. The dedicated PROFIBUS module draws only 2 W from the internal backplane, keeping the controller’s total base power demand at 7.5 W. Parameter access is also possible over an RS-232 service port that supports cable runs up to 15 m and baud rates up to 115 kBaud for bench-top setup. For high-resolution feedback, Option 1 supports EnDat 2.1, 1 Vpp, or 5 V TTL encoder signals so the drive can close position loops without external converters. The primary feedback channel, labeled En1, accepts a resolver excitation of 18.2 Vpp AC at 4 kHz, allowing analog HSF or resolver transducers to be connected without additional signal conditioning. The secondary feedback supply on En2 can source 350 mA to incremental sensors and shuts down automatically under overload.
The En2 header delivers a regulated 5.0 VDC rail so incremental encoders share a local supply rather than drawing from the control cabinet bus. Safety resources are integrated on the same board; the inputs are evaluated at 24 VDC / 3 mA, and the solid-state outputs can switch up to 24 VDC / 0.5 A for interlocking contactors, while a relay circuit rated at 24 VDC / 1 A handles hard-wired emergency stops. These circuits support the controller’s Safe Motion architecture, enabling functions such as safe torque off and safely limited speed without adding external relays during setup, maintenance, or fault recovery.
