Product Description:

The CSH01.1C-PB-ENS-NNN-MA1-S1-S-NN-FW is a motion logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in modular drive cabinets, it links servo inverters to higher-level PLCs and sensors so axes receive time-critical position, velocity, and safety commands. Integrated fieldbus and analog interfaces allow the unit to supervise one drive channel, capture process variables, and issue relay status signals, making it a central coordination element in packaging lines, material handling systems, and other automated production cells.

The controller is engineered for low thermal load, and its configured demand is 18.5 W, so cabinet ventilation can remain minimal during continuous duty. When power is first applied, an inrush of 4 A is tolerated for 100 ms, a pulse width that affects the sizing of upstream fuses and soft-start circuits. Digital networking is handled through PROFIBUS at 12 MBaud, delivering deterministic telegrams to the drive. An auxiliary RS-232 service port operates at 115 kBaud for communication across cables up to 15 m. The embedded encoder interface has a bandwidth ceiling of 500 kHz, allowing high-resolution SinCos signals to be processed without aliasing. Two MA1 analog inputs and two analog outputs are included, and each output can source 10 mA for transducer excitation or valve actuation.

On the encoder side, a 120 Ω termination and a draw of 500 mA are backed by a sensor rail stabilized at 11.6 V. This helps prevent line reflections and voltage sag during high-speed feedback. The MA1 mezzanine board presents an input impedance of 1000 kOhm, ensuring minimal loading on connected potentiometers and pressure transmitters. Discrete status signaling is handled by a relay rated for 1 A, while the dedicated S1 safety driver can deliver 0.5 A to external contactors when a safe-torque-off demand is issued.
