Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-NN-ENS-NNN-NNN-NN-S-NN-FW, an axis controller from the CSH Advanced Controllers series. The card fits into IndraDrive power sections and manages real-time motion commands for motors, actuators, and sensor feedback in automated cells. By handling interpolation and I/O conditioning on the board, it simplifies cabinet wiring and allows the wider automation system to coordinate multiple drive axes with deterministic timing.

The controller provides two symmetrical analog outputs. Each channel can source up to 1 mA and is designed for a load impedance of 5 kΩ, so differential converters or drive references receive stable voltage levels. Step resolution is 19.5 mV/inc across a full-scale span of 5 V, enabling fine setpoint generation for torque or velocity commands. TTL reference inputs accept edge frequencies up to 400 kHz, which supports high-resolution encoder emulation or pulse-direction control. Communication toward external PLCs is limited to a point-to-point RS-232 service port. Two Form C relays switch DC loads of 1 A at 30 V, and all discrete outputs share a total sourcing capacity of 1000 mA.

The feedback side includes a 12-bit ADC that digitizes incremental encoder tracks with a 12-bit word length, while the line receiver presents an input resistance of 120 Ω to maintain signal integrity over long cables. The board supplies encoders with a regulated output of 11.6 V through its D-Sub 15-pin female connector, and each power pin can deliver up to 500 mA for resolvers, Hiperface, or EnDat transducers. A dedicated monitor sums the current of all encoder and sensor supplies to preserve the 1000 mA card limit. It is intended to operate within coordinated drive systems where a higher-level controller manages cell-level sequencing and supervision.
