Product Description:

The CSH01.1C-PB-EN2-EN1-NNN-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive inverter stacks, this module coordinates drive tasks, field communication, and integrated safety logic in industrial automation cells. By combining encoder evaluation, bus interfacing, and a local display within a compact slot, it streamlines multi-axis motion control and simplifies cabinet wiring for packaging, printing, or material-handling equipment. The unit acts as the command layer, translating application instructions into synchronized torque, speed, or position commands for connected power sections.

It draws a base logic load of 7.5 W, so heat dissipation remains low inside the drive shelf. Command traffic to the PLC is handled through PROFIBUS, and the front panel includes a D-Sub 9 female connector for that channel. Integrated position feedback processing supplies the first encoder with a regulated rail of 5 V DC and can deliver up to 350 mA, accommodating high-resolution sensors that match the selectable EnDat 2.1 / 1 Vpp / 5 V TTL interface. A single-line panel display provides local status indication, and a relay contact rated at 24 V DC / 1 A is available for auxiliary signaling.

An additional input stage supports a Resolver / HSF feedback loop, energized by an internal 8 V source and an 18.2 Vpp excitation signal, which allows the controller to operate resolver transducers on secondary axes. For service or diagnostics, it includes an RS-232 port that reaches 115 kBaud, enabling rapid parameter transfer without using the fieldbus. Functional safety is implemented through dedicated terminals; each input channel accepts a logic level of 24 V / 3 mA, while the solid-state output can switch up to 24 V / 0.5 A for downstream contactors. These safety paths work with the internal Safety Technology I/O supervision to support stop and enable sequences.
