Product Description:

The CSH01.1C-CO-ENS-MEM-MD1-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive modular drive stack, the unit coordinates drive regulation, fieldbus communication, and functional safety tasks in automated machinery. It serves as the control layer between a PLC and the power section, translating motion commands into regulated axis behavior for servo applications. This arrangement supports precise supervision of position, speed, and torque in assembly lines, packaging cells, and material-handling stations where synchronized motion is required.

Power consumption for the logic section is limited to 7.5 W, so cabinet thermal budgets stay low. Fieldbus communication is handled through CANopen / DeviceNet, and the DeviceNet master can address up to 64 slave nodes, which supports distributed I/O layouts without requiring a separate network controller. Feedback is handled by a triple encoder interface that accepts IndraDyn / Hiperface / 1 Vpp signals, while the transducers receive a regulated 12 V supply inside the unit. This allows the control section to work with several common feedback types used in servo systems. The Safe Motion architecture keeps drive-integrated safety functions separated from the standard control path.

The MEM channel carries high-speed command data along motor cables, with a maximum line length of 40 m and a signal clock of 1 MHz for synchronization across multiple drives in the same machine section. On the MD1 expansion, the unit provides 12 opto-isolated digital inputs for sensor feedback and 8 transistor outputs that can switch loads up to 24 VDC at 0.5 A. An auxiliary relay contact rated at 24 VDC, 1 A is also available for control of pneumatic valves or motor contactors. These I/O resources let the controller exchange status and command signals with nearby devices during machine operation.
