Product Description:

The CSH01.1C-PB-ENS-MEM-MD1-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit plugs into an IndraDrive power section and supervises axis functions, I/O handling, and safety logic within an automation cell. By combining motion control with fieldbus communication, it lets machine builders synchronize drives, coordinate sensors, and execute Safe Motion monitoring from a compact module. Designed for cabinet installation, it forms the processor layer that interprets encoder feedback and sends commands to downstream inverters and actuators. This modular arrangement keeps the control electronics separate from the power stage while preserving coordinated drive operation.

Its base electronics draw only 7.5 W, so thermal load on the panel is minimal. For network integration, the controller carries a PROFIBUS interface through a 9-pin D-Sub connector, and service access is available through the built-in RS-232 port. The option card provides 12 x 24 V digital input channels and 8 x 24 V digital output channels for sensors and actuators, allowing standard field signals to be exchanged without separate discrete I/O hardware. The emulation channel supports cable runs up to 40 m and reproduces pulse trains at 1 MHz, allowing high-resolution feedback to be passed to external controllers.

The base board includes a standard encoder evaluation circuit that accepts absolute and incremental formats through a 15-pin D-Sub connector. It sources up to 500 mA at 11.6 V to power external sensors, which helps support connected feedback devices directly from the control section. The Safe Motion package monitors position and velocity through these channels and can execute STO, SS1, or SOS reactions through dual safety terminals. Command channels tolerate a safety input of 24 V / 3 mA, while the protected driver can switch field devices at 24 V / 0.5 A to trigger brakes or contactors during a stop.
