Product Description:

The CSH01.1C-PL-EN2-EN2-NNN-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed on an IndraDrive power module, it interprets motion commands, executes embedded PLC tasks, and distributes synchronized setpoints to each drive axis, which supports precise positioning and speed control in automated machinery. Its integration of analog, parallel, and encoder resources lets the controller bridge high-level machine logic with field devices without requiring external I/O cards. This arrangement keeps control, feedback handling, and local logic within the same drive platform.

The analog channel accepts differential signals up to ±10 V, and a high input impedance of 160 kΩ helps prevent source loading so connected sensors can maintain their calibrated span. The module can retransmit velocity or torque demands through a 5 V analog output that supplies up to 1 mA, which is sufficient for many drive reference inputs while limiting heat dissipation inside the rack. Command and status bits move over a Parallel Interface that terminates on a D-Sub 37 connector, giving the application 16 optically isolated inputs and 16 transistor outputs for fast handshaking with actuators, limit switches, or user panels. A standard front control panel supports local parameter access, and the relay contact is rated for 24 V DC at 1 A for auxiliary signaling.

Position feedback is handled by two independent encoder links specified as 2 x EnDat 2.1 / 1 Vpp / 5 V TTL. Each channel can drive external loads down to 35 ohms while sourcing up to 350 mA from a regulated 5.0 V DC supply, which supports stable feedback transmission over longer cable runs with low signal attenuation. Typical internal demand is only 20.5 W, helping multiple sections share a compact cabinet without placing a heavy load on the thermal budget. The control section has no integrated safety technology, so any required STO or SS1 functions must be provided by the host drive or by external relay logic.
