Product Description:

The CSH01.1C-PB-NNN-MA1-MD1-L2-S-NN-FW is a motion-logic controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In a multi-axis drive system, this unit acts as the command stage that interprets fieldbus data and orchestrates torque, speed, or position loops in attached power sections. By placing deterministic control intelligence close to the axes, it shortens response times and coordinates movement for packaging machines, handling gantries, and similar automated equipment.

Fieldbus communication is handled through PROFIBUS, and the integrated interface supports transfers up to 12 MBaud, allowing synchronous set-point updates across multiple drives. For local analog feedback, the MA1 board provides two analog inputs and two analog outputs; each output provides a reference of 5 V or a sourcing capacity of 1 mA. The digital-to-analog path is processed at 12 bit resolution with a step size of 5 mV per increment, giving the controller fine voltage granularity for actuator or sensor excitation. All MA1 signals are routed through a D-Sub 15-pin female connector for straightforward panel wiring.

Complementing the analog layer, the MD1 section offers 12 digital inputs and 8 digital outputs for limit switches, drive enables, or diagnostic flags. When serial diagnostics are needed, the RS-232 port streams data at 115 kBaud over cables up to 15 m long, providing a fallback channel for setup and diagnostics. Each analog output can also deliver up to 10 mA when driving low-impedance loads. Functional safety is handled by a dedicated circuit; a D-Sub 9-pin female connector carries the hard-wired request that triggers Safe Torque Off, removing energy from the attached power stage without affecting fieldbus traffic.
