Product Description:

The CSH01.1C-ET-ENS-NNN-NNN-S2-S-NN-FW control section is supplied by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. This module slots into an IndraDrive power unit and functions as the command layer for axis positioning, speed regulation, and coordinated motion. By linking fieldbus networks to drive hardware, the unit translates PLC instructions into real-time drive control within industrial automation systems.

The controller accepts analog reference signals within a tolerance of ±10 V, allowing direct connection to proportional transmitters or motion master outputs without additional scaling hardware. These inputs have a high input impedance of 160 kΩ, so signal sources are not heavily loaded during operation. Six digital command channels are rated for 24 V / 3 mA, which allows the control section to be driven from standard PLC transistor outputs while still meeting IEC 61131 logic levels. For time-critical probing tasks, an internal capture circuit provides a resolution of 1 µs, so edge-triggered position marks are registered accurately on fast rotary axes. System traffic is exchanged via Multi-Ethernet, allowing the same hardware to operate on EtherNet/IP, PROFINET, or Sercos over Ethernet networks without changing option cards.

Analog feedback toward external recorders is provided through an output stage rated at 5 V / 1 mA, giving a low-noise monitor point for torque or velocity values. When actuator interlocks are required, the module offers eight sourcing outputs that can switch 24 V / 0.5 A, which is adequate for relay coils or brake solenoids. Integrated encoder support supplies up to 500 mA at 11.6 V, so high-resolution EnDat or SSI sensors can be powered directly from the card. Despite these interfaces, the board draws only 7.5 W during normal service, which helps limit cabinet heat rise, and a brief 4 A inrush is specified for startup. Safe Motion technology is included, and relay contacts support a maximum pulse width of 100 ms.
