Product Description:

The CSH01.1C-SE-EN1-ENS-MA1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power unit, it executes motion commands, manages feedback devices, and exchanges real-time data with higher-level PLCs. This modular product forms the logic core of multi-axis drive assemblies used across material-handling, packaging, and machining lines where coordinated axis control is required. Because it serves as the control section rather than the power stage, it concentrates on command processing, signal handling, and communication inside the drive system. That arrangement lets the power unit and control logic remain integrated in one modular drive platform.

The section’s internal electronics draw a base power of 7.5 W, so cabinet thermal loading remains low. Parameter storage, encoder evaluation, and SERCOS interface logic are supplied by the EN1 line at 8 V. During power-up, the DC bus must tolerate an inrush of 4 A that persists for 100 ms, and this brief surge should be considered when sizing fuses and contactors. For local setup and service, the onboard RS-232 port supports data exchange up to 115 kBaud. Two analog input channels and two analog output channels are present on the MA1 option card, and each channel is processed through 12-bit converters. Separate sockets accept resolver/HSF and IndraDyn, HIPERFACE, or 1 Vpp feedback devices, allowing the unit to work with a broad range of motor encoder formats.

Field networking is handled through SERCOS II carried on a fiber-optic ring, providing deterministic cycle times for axis groups. Encoder supply on the ENS rail is stabilized at 12 V, and the safety circuit uses a logic voltage of 24 V delivered to the drive through a D-Sub 9-pin female connector. The MA1 converters process analog position and process signals, while the separate feedback interfaces support several common motor encoder types. This separation helps keep motion-related signals organized alongside network communication. The control section can therefore manage both encoder handling and real-time command exchange within the same drive assembly.
