Product Description:

The CSH01.1C-NN-EN1-NNN-MA1-S1-S-NN-FW is a motion and machine controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It plugs into an IndraDrive control section and coordinates axis regulation, logic processing, and peripheral communication for automated production equipment such as pick-and-place units, packaging lines, and machining centers. The module supplies deterministic cycle timing so that connected drives receive precise velocity and position commands required for synchronized multi-axis operation.

Base power consumption is only 7.5 W, which keeps cabinet heat rise minimal and allows passive ventilation in compact enclosures. A single-line control panel display on the front of the unit permits simple status reading without an external computer. Position feedback is accepted through a resolver/HSF interface; the encoder supply rail delivers 8 V, and the incoming HSF data stream is digitized with a 12-bit converter. The HSF port has an input resistance of 10 kΩ and supplies 250 mA for sensor excitation, supporting low-impedance transducers located several meters away. At startup, the logic experiences an inrush draw of 4 A, so upstream fusing and power sequencing must account for that short-term surge. A built-in RS-232 maintenance channel supports parameter access at rates up to 115 kBaud, allowing direct local setup without additional fieldbus hardware.

The installed MA1 option board provides 2 differential channels of ±10 V analog input, two ±10 V analog outputs, and an input impedance of 1000 kΩ for precise voltage measurement from high-impedance sensors. Each analog output updates in 5 mV steps, giving an effective resolution of 5 mV/incr for fine command signals to external actuators. The S1 supply interface feeds the controller with a stabilized DC 24 V line and can deliver up to 1.6 A to internal electronics and option cards. System-level risk reduction is addressed by the integrated Safety Technology I/O feature, which offers hard-wired safe stop channels that can be tied directly to emergency circuitry without external relays.
