Product Description:

The CSH01.1C-ET-EN2-NNN-MEM-S2-S-XP-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive rack, it serves as the motion and communication unit for servo axes, reading encoder data, executing position loops, and forwarding setpoints to the power section. Dedicated terminals are provided for Ethernet, incremental encoder feedback, memory expansion, and RS-232 service access, which keeps network, diagnostic, and feedback wiring in one slot while preserving cabinet depth. This arrangement also helps keep the control section organized when several axes are installed side by side.

Its base power consumption is 7.5 W, so the thermal load on densely packed drive stacks stays low. During power-up, the module draws an inrush of 4 A lasting up to 100 ms, so the upstream control power must tolerate a brief startup surge. The Ethernet interface uses an RJ-45, 8-pin jack and supports the 100Base-TX standard over twisted-pair runs up to 100 m, which allows direct connection to standard industrial switches. Incremental encoder channel EN2 also provides a regulated 5.0 V supply for attached sensors, helping maintain stable feedback signals without an external source.

The RS-232 port supports transfer rates up to 115 kBaud across shielded leads limited to 15 m, which provides reliable access for setup and diagnostics. The MEM connector can clock output data at 1 MHz with a drive capability of 20 mA, making it suitable for fast trigger and synchronization tasks. For legacy incremental feedback, EN2 tolerates differential loads down to 35 ohms along cable runs reaching 75 m, so shielded pairs can be routed through moving cable paths without excessive attenuation. This combination of service, memory, and encoder connections allows the controller to support both newer networked systems and existing feedback hardware within the same drive platform.
