Product Description:
The CSH01.1C-NN-EN1-NNN-MA1-NN-S-NN-FW advanced controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in modular Rexroth drive racks, the unit closes motion loops, conditions feedback signals, and issues command values to the power stage of a drive. By handling interpolation, velocity profiling, and diagnostic reporting directly on the card, it relieves the PLC of time-critical axis tasks and allows streamlined integration in packaging lines, assembly stations, and material-handling robots.
Control of a single mechanical axis is possible because the card is rated for 1 axis. Position feedback wiring on the En1 terminal can be powered with 8 V DC, and the device accepts mixed-signal information through a resolver and HSF interface, so both coarse and high-speed formats can be used. Two analog input channels on the MA1 connector are digitized at 12-bit resolution, and the differential lines help tolerate typical field-borne noise. On the same connector, two analog outputs can drive loads down to 1 kΩ, and they are also quantized at 12-bit depth to maintain symmetry between incoming and outgoing process variables.
Additional onboard resources support decentralized sensing, fine drive tuning, and diagnostic connectivity without reconfiguring the main fieldbus. The two logic-level inputs present a factory-set impedance of 160 kΩ, allowing direct connection to standard 24 V sensors while keeping source loading minimal. Each internal digital-to-analog driver can source up to 1 mA, which helps protect delicate transducers while still supporting the full 8-bit output range reserved for status signaling. Rotor position tracking is refreshed at 4 kHz from the resolver excitation, which is produced with an 18.2 Vpp sinusoid to maintain signal integrity over shielded motor cables. A front-panel RS-232 port reaches 15 m and supports a single service node for local parameter access.
