Product Description:

The CSH01.1C-S3-EN2-NNN-NNN-L1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. A standard control panel on its face allows local parameter adjustment without a programming terminal. This module slots into IndraDrive power sections to coordinate servo axes, handle feedback, and exchange real-time data with plant networks. Within an automation cell it acts as the processing core that interprets motion commands, supervises safety states, and relays status information to higher-level PLCs during multi-axis drive control.

The control electronics draw 7.5 W from the internal bus, a low demand that reduces cabinet heat and allows dense stacking of drives. For secondary feedback, the EN2 channel provides an isolated supply of 5.0 V, letting EnDat or TTL encoders power directly from the card. The same channel accepts signal streams up to 1000 kHz, so high-resolution encoders can be sampled without aliasing. With an output capability of 350 mA, the board can support long feedback lines without excessive voltage drop. Position information is decoded through the EnDat 2.1 / 1 Vpp / TTL interface, giving flexibility for different sensor formats on a single axis.

The mechanical outline is compact: depth is 103 mm, height reaches 241 mm, and width is 49.5 mm, so the unit fits shallow control cabinets while maintaining clearance for airflow. During power-up, an inrush of 4 A lasting 100 ms charges the controller’s capacitors, and fuses must tolerate this brief surge to avoid nuisance trips. Functional safety is supported through a Starting Lockout option that disables torque until the drive receives an enable signal. High-speed communication to the drive network travels over 100Base-TX SERCOS III through dual 8-pin RJ-45 ports, and an auxiliary RS-232 service link can span 15 m.
