Product Description:

The CSH01.1C-SE-ENS-EN1-MA1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive stack, this module manages motion, feedback, and machine safety signals for servo axes in automated equipment. It forms the interface between field-level drives and higher-level PLCs, translating program commands into synchronized position and speed instructions that keep conveyors, pick-and-place units, and packaging machinery operating within specification. This arrangement lets one control section coordinate commanded motion with actual encoder data and safety-related signals at the drive level.

The controller’s logic electronics consume only 7.5 W, minimizing panel heat while powering the communication core that uses SERCOS II at a bus rate of 16 MBaud for deterministic drive networking. Encoder channel 1 provides an isolated supply of 11.6 V at up to 500 mA and accepts incremental or absolute position feedback through the IndraDyn, Hiperface, 1 Vpp interface, enabling direct connection of high-resolution motors. A second channel can read resolver or HSF signals, which allows mixed feedback types on the same axis and supports both newer motor systems and existing machine layouts. Deterministic communication and flexible feedback handling help the controller maintain stable axis coordination during positioning and speed regulation.

The MA1 option card adds 2 differential analog inputs for signals from devices such as load cells, while two voltage outputs span ±10 V for proportional valve or inverter references; an additional 5 V, 1 mA onboard output supplies low-power sensors. Resolver excitation is delivered at 18.2 Vpp and 4 kHz, matching common industrial transducers without external drivers. Integrated Safety Technology I/O routes emergency-stop and guard-door circuits through the module, and its dedicated solid-state channel can switch up to 0.5 A to release or inhibit connected brakes. The local analog and safety connections reduce the need for separate interface hardware elsewhere in the drive stack.
