Product Description:

The CSH01.1C-SE-EN2-ENS-EN1-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a motion-control master for IndraDrive servo inverters, this controller coordinates axis positioning and safety signals inside automated machinery. By hosting SERCOS real-time communication, it links drives and higher-level PLCs with deterministic data exchange. This role lets the controller manage coordinated motion across multiple axes while passing status information back to the machine control. Its integrated Safety Technology I/O also supports certified shutdown paths without external relays, which helps keep machine wiring compact in guarded systems.

The analog interface presents an input impedance of 160 kΩ, so connected sensors place only a light load on the circuit. Analog outputs are referenced for setpoint generation, and the module’s base electronics draw 7.5 W at standby, which helps limit internal heat during idle operation. Discrete command lines register an ON state once they exceed 15 V, improving noise tolerance in factory wiring runs. Each digital output can source up to 500 mA, which is suitable for indicator lamps or interposing relays. That arrangement supports direct field wiring for simple status devices without adding separate output boosters. Resolver channel EN1 excites the rotor transducer with a carrier of 4 kHz, allowing stable feedback processing during motion control.

The same resolver channel supplies the excitation at 18.2 Vpp, while the secondary encoder port EN2 offers a stabilized 5 V rail for TTL or sine-cosine feedback devices. For multiturn devices on the ENS port, the board provides 11.6 V and supports tracking frequencies up to 400 kHz, allowing the controller to read encoder activity at high speed. The feedback ports accommodate different encoder formats on separate connections, which gives the control stack flexibility when mixing motor and auxiliary feedback sources. The separate sensor supply powers connected feedback electronics through that port. Safety inputs and outputs share an isolated bus that may be loaded to 1.6 A, which supports emergency-stop chains that include light curtains or door switches.
