Product Description:
The CSH01.1-SE1-NNN-EN2-NNN-NNN-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive systems, this module executes motion commands, conditions encoder feedback, and drives field-level actuators through its analog and digital outputs. By combining power distribution, signal conversion, and protocol handling on one board, it reduces cabinet space while supplying deterministic control to servo axes in automated machinery. It is used where the drive must coordinate command processing and feedback evaluation within the same control platform.
The board’s analog interface sources 1 mA at a nominal output level of 5 V, giving proportional drive references for speed or torque loops. Internal electronics draw a maximum of 7.5 W, so heat dissipation remains low even when every channel is active. Feedback is exchanged through the EnDat 2.1 protocol, and the encoder connector delivers a regulated 5 V supply at 200 mA for sensor electronics. Control logic and discrete inputs share a bus that must be fed with 24 V DC, and the card pulls 1.1 A from this rail during steady operation while accepting a 4 A inrush when first energized. Sine-cosine feedback stages present 1 Vpp differential signals, while incremental tracks are available as 5 V TTL square waves for high-resolution position capture. This arrangement lets the controller handle both command output and position feedback without requiring separate interface hardware for common encoder types.
An onboard relay can switch loads up to 1 A, provided the external circuit also runs on 24 V DC; this contact is often wired to motor contactors or safety chains. Pulse outputs are limited to a maximum width of 100 ms, which helps prevent unintended latching of downstream devices. A dedicated EN2 expansion consumes only 6 W, allowing the total controller stack to remain within common 24 V power budgets. For digital drive diagnostics, the square-wave track maintains a constant amplitude of 5 V TTL, which supports clean edge detection by PLC counters without additional line drivers. The combination of relay control, pulse handling, and diagnostic signaling supports integration with surrounding machine control circuits.
