Product Description:
The CSH01.1C-S3-EN1-EN2-MEM-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts on an IndraDrive power stage and governs motor loops, safety functions, and real-time bus traffic in automated machinery. In operation, it manages feedback processing and coordinated drive behavior for axes that must respond accurately to motion commands. Integrated encoder ports, serial service access, and SERCOS III networking simplify cabinet wiring and support synchronized multi-axis motion.
The control electronics operate from a 24 V DC control supply and have a basic power consumption of 7.5 W for the logic, while the encoder emulator requires an additional 2 W and the operator panel requires 1 W. The unit provides two analog outputs for ±10 V references, and the local I/O block includes 11 digital inputs that treat voltages above 15 V as ON and below 5 V as OFF. It also provides four digital outputs that source 24 V signals for relays or indicators. At startup, the section can draw 4 A for up to 100 ms, so the control supply must support that short inrush demand. En1 accepts HSF or resolver feedback and supplies 8 V to the transducer, while En2 supports EnDat 2.1, 1 Vpp, or 5 V TTL encoders and supplies 5 V. These connections let the section exchange reference, status, and feedback signals directly with nearby drive components.
Deterministic bus exchange is handled by SERCOS III through dual 8-pin RJ-45 ports that comply with IEEE 802.3 and use standard Ethernet wiring. A maintenance laptop can connect through the RS232 interface on an 8-pin MiniDIN plug, and an SSI emulator mirrors position data to external hardware when position information must be passed onward. Time-critical registration tasks rely on a probe circuit capable of recognizing edges within 4 µs, and a single normally open relay contact is available for drive-ready feedback. The network ports are built into the section, so real-time communication is available directly at the controller.
