Product Description:

The CSH01.1C-SE-NNN-NNN-NNN-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Installed beside an IndraDrive power module, it acts as the motion and I/O processor that links servo axes to supervisory automation systems and enables coordinated positioning and torque regulation on production equipment. Its modular layout keeps the control functions separate from the power stage, so the same drive platform can be used across different machine layouts without changing the basic power hardware.

Its control electronics are powered from a dedicated 24 V DC supply rail, and the controller itself draws only 7.5 W during steady-state operation, so it adds little heat to the enclosure. At startup, the supply must accommodate a peak of 4 A for up to 100 ms, after which current falls to nominal levels. Real-time motion commands and feedback are transferred over the fiber-optic SERCOS II ring, allowing synchronized cycle times with adjacent drives. A separate RS-232 port is available for local serial communication. Discrete input channels detect an off state below 5 V and an on state above 15 V, allowing direct connection to common industrial sensors. Individual transistor outputs can source 500 mA, while the shared group limit is 1000 mA. Three option slots remain blank, leaving space for future fieldbus or encoder extensions.

The base card includes dedicated blocks for digital I/O, analog I/O, and a relay channel, enabling direct termination of peripheral devices without add-on modules. The relay is rated for 1 A DC and can switch up to 30 V DC, which suits status lamps, contactors, or low-power valves. Functional safety is implemented by Safe Torque Off; the feature is accessed through a D-Sub 9-Pin Female connector that routes dual-channel enable signals to the drive. This arrangement places standard interfaces and hardware-based safety on the same board, which helps conserve cabinet space.
