Product Description:

The CSH01.1C-PB-EN1-EN2-NNN-NN-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed in an IndraDrive assembly, it translates network directives into motor-ready commands so that MHD and MKD servomotors can execute accurate positioning, velocity, and torque tasks inside automated cells, conveyors, and pick-and-place stations. By combining PLC-level communication, sensor feedback, and local signal conditioning, the card becomes the central motion processor in many industrial automation platforms.

The unit accepts incoming analog references over a range of ±10 V, and its input path presents a high input impedance of 160 kΩ, which protects the source from current draw. Field-level communication uses PROFIBUS through a D-Sub 9-pin female connector, allowing drive parameters to be updated in real time. Digital inputs load the controller by only 3 mA, while its transistorized outputs can source up to 0.5 A for contactors or status lamps. A front-mounted RS-232 service port operates at up to 115 kBaud for setup and diagnostics. Slot 1 supports resolver or HSF feedback, and the HSF channel drives a 1.0 V differential signal from an internal 8 V supply so high-speed feedback does not require external conditioning.

For secondary feedback, the Encoder 2 interface supplies 5.0 V at up to 350 mA, which is enough to power multiturn encoders on large axes. When a resolver is connected, the board provides a carrier frequency of 4 kHz and an excitation level of 18.2 Vpp to achieve precise sine-cosine decoding. Slot 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, giving machine builders flexibility when selecting absolute or incremental transducers. These interfaces let the control section close fast position loops, synchronize multiple drives, and report status to higher-level controllers without additional interface hardware.
