Product Description:

The CSH01.1C-PB-ENS-NNN-MEM-S2-S-XP-FW is a single-axis controller module from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It installs in Rexroth drive systems to execute axis control, I/O processing, and fieldbus communication tasks required for coordinated motion. By combining real-time processing with integrated encoder interfaces, the unit serves as the command layer that links motion commands from higher-level PLCs to power sections driving servo motors.

The analog input channels present an impedance of 160 kΩ, so external sensors see a high resistance that minimizes loading error. Each analog output step equals 19.5 mV/inc, giving voltage commands fine resolution for drive tuning. Fieldbus traffic is handled on PROFIBUS-DP, allowing exchange of setpoints and diagnostics with the plant PLC. The RS-232 port supports transfers up to 115 kBaud for serial communication. A power-up surge of 4 A should be considered when sizing shared 24 V supply rails, and the incremental encoder emulation can stream differential signals up to 1 MHz for high-speed position loops. Digital outputs can switch 24 V loads at 0.5 A for relay actuation.

The module draws only 7.5 W during steady operation, so cabinet thermal load stays low. Safety-related commands are routed through the Safe Motion interface, which sources 24 V / 0.5 A when an enabling output is required. The integrated encoder supply delivers 12 V, eliminating the need for an external sensor power module. Across all sourcing outputs, the aggregate limit is 1000 mA, which should be considered when multiple feedback devices and status lamps are wired. Position feedback can also be transmitted over an emulation cable up to 40 m long, keeping controller cards in the cabinet while encoders remain on moving axes. The digital output block shares the same 24 V potential to simplify common return wiring.
